5.1 Product Design

5.2 Acoustics
Cases shall not impair or degrade the acoustic performance of a device.

5.2.1 Call Quality
Cases shall not impair or degrade the user experience making and receiving audio calls over a cellular
network or audio/video calls using FaceTime in both handset and speakerphone modes. Cases should
not change the frequency response of the speakers or microphones. In addition, the user should not
hear any distortion or echo resulting from using the case.

Cases shall not obstruct any microphones during a phone call. Occluding microphones can result in
call quality degradation.

5.2.2 Speaker to Microphone Coupling
Cases shall not facilitate the conduction of sound from any speaker to any microphone. Such sound
conduction may cause echoing in phone calls.

5.2.3 Speaker/Microphone Openings
Device speaker/microphone port locations vary from model to model, see Device Dimensional Drawings
(page 253).

5.2.3.1 Thin Cases (≤2.25 mm)

Thick case channels may act as a resonance chamber and detune microphone/speaker frequency
response. The resulting frequency response may vary according to channel size/shape.

If a thick case does not maintain a proper seal against the device between microphone/speaker channels,
the case itself may become an acoustic chamber.

The ambient light sensor and proximity sensor locations for various devices are indicated in the Device
Dimensional Drawings (page 253). Some of the dimensional drawings specify a keep-out area around
these sensors.

5.5 Magnetic Interference
Cases shall not interfere with the device's:

 ● Magnetic compass.
 ● Rear camera autofocus (AF).
 ● Rear camera optical image stabilization (OIS), if present.
 ● Front camera autofocus, if present.

See Magnetic Interference (page 26) for additional details.

5.6 Touch ID
Accessories shall not inhibit use of the device's Touch ID sensor. Touch ID sensor keep-outs for devices
can be found in Device Dimensional Drawings (page 253).

Cases overlaying the sensor may cause users to have difficulty using Touch ID.

5.7 Camera
The camera field of view (FOV) and the illumination provided by the flash are designed for each device
camera. It is exceptionally important manufacturers consult Device Dimensional Drawings (page 253)
for each device and do not assume parameters are shared between devices.

Images from the camera may be affected by the geometry, color, and surface finish of the case.

Note:
Apple recommends a semi-gloss black material or coating around the camera and flash
opening.

5.7.1 Geometry
The camera lens FOV shall not be blocked. Making an opening too small around the camera and flash
may block the lens FOV and the illumination from the flash. Blocking the FOV may cause vignetting in
the image, where one or more corners of the image are darker than the center. Blocking marginal rays

5.5 Magnetic Interference

just outside the lens FOV may also reduce the sharpness and contrast of the image. Blocking flash
illumination may cause haze in the image, resulting in reduced contrast. See Device Dimensional
Drawings (page 253) for the camera keep-out.

Case openings shall not be designed in a manner directing stray light into the camera lens. If the opening
is too narrow or too steep, it may reflect light into the camera lens washing out the image or adding a
color cast. Adding a chamfer to the openings near the camera may help direct stray light away from
the camera lens. When the device includes a flash, a narrow or steep opening may reflect light from
the camera and flash opening back into the camera lens. This may cause images to appear washed
out or cause artifacts. Designers should also ensure mechanical keep-outs as outlined in the Device
Dimensional Drawings (page 253) are maintained with worst-case X-Y placement tolerances to minimize
the risk of haze.

5.7.2 Color
Light reflected from a case may carry the color of the case. Black material or black coatings may help
avoid color bleeding into the camera lens. The darker the color the less likely light from a flash or
external source may be reflected off the case and into the camera lens.

5.7.3 Surface Finish
Semi-gloss materials may help direct reflected light away from the camera lens. Matte or diffusing
materials scatter light in all directions increasing the likelihood light from a flash or a strong external
light source will be reflected into a camera lens.

5.8 Reliability
Cases shall be tested to verify they will withstand long-term use under typical use conditions, and will
not impair or functionally degrade a device, cause damage to the device or its immediate surroundings,
or adversely affect the user.

5.8.1 Device Insertion and Removal
Cases shall hold the device securely while permitting easy insertion and removal. A case shall not cause
Scratches and Damage (page 25) to the device by the repeated insertion and removal of the device
from the case under conditions representative of long-term use in a variety of environments.

An adapter accessory is a dongle or a Built-In Cable (page 22) enabling connections between physically
incompatible devices and accessories.

Unless otherwise specified, accessories may integrate one or more adapter components as well as
other accessory features to create more advanced multi-port adapters. For example, a Lightning or
USB-C adapter may support audio, power, external storage, media controls, app communication, and
more.

See the Accessory Interface Specification (page 23) for more information.

9.1 Headset Adapters (Lightning to 3.5 mm)

9. Adapters

9.4 Lightning to USB Micro-B Adapters

AC power adapters convert AC "mains" power to DC for the purpose of providing power to a device.
They may provide power using one or more of the following:

 ● USB-C Receptacle (page 244) combined with a USB-C cable or USB-C to Lightning cable.
 ● USB-A Receptacle (page 239) combined with a USB-A to Lightning cable.
 ● Device Power (Inductive) (page 138).

10.1 Converter Switching Frequencies
Device touchscreen or audio functionality may be degraded if converter switching frequencies do not
meet the following requirements:

 ● Under loads greater than 5 mA, converter switching frequencies shall be above 22 kHz.
 ● Under loads greater than 20 mA, converter switching frequencies:

 ● Shall be above 60 kHz.
 ● Should be above 450 kHz.

10.2 YCAP AC Capacitor
AC power adapters should include a YCAP AC capacitor (up to 1000 pF) between the primary and
secondary sections of the adapter's transformer to reduce common-mode noise at switching frequencies.
These frequencies or their harmonics can interfere with device touchscreen sensors.

10.3 Impedance Stability
AC power adapter series impedance should not change abruptly. Sudden changes in impedance may
cause touchscreen sensor output oscillations.

Bridge diodes used in full-wave bridge rectifiers can be a major source of abrupt changes in the series
impedance. If the bridge diodes have large inherent reverse capacitance (greater than 100 pF), then
the net impedance change due to diode switching may be acceptably small. However, diode reverse
capacitance may decrease in more compact IC designs due to decreased chip area.

10. AC Power Adapters

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

74

Impedance of bridge diodes with unacceptably low reverse capacitance can be stabilized using the
example circuit shown in Figure 10-1 (page 75) and Table 10-1 (page 75). In this example, capacitors
C1, C2, C3, and C4 have been placed in parallel with diodes D1, D2, D3, and D4 to stabilize the bridge
impedance. Their values are larger than the inherent reverse capacitances of the diodes.

Resistors R1, R2, R3, and R4 are optional; if included, they can block noise at very high frequencies,
which can help with EMI compatibility. The recommended values of R1, R2, R3, and R4 in Table 10-1
(page 75) were chosen to have trivial levels of impedance relative to the impedances of C1, C2, C3,
and C4 at power line frequencies.

Devices may accept user input from accessory keyboards in place of the onscreen keyboard.

14.1 Requirements
Accessory keyboards shall:

 ● Support the Human Interface Device (HID) (page 203) protocol.
 ● Not identify themselves as Apple-branded accessories, for example, using the Apple Vendor ID

and/or Product IDs.

Keyboard keys exhibiting any of the following behaviors are explicitly prohibited:
 ● Send anything other than 'key pressed' or 'key released' for key(s) physically pressed/released.
 ● Emulate combinations or sequences of keys (for example, a Copy button sending x-C or macros

generating a timed sequence of events).
 ● Emulate timed user actions, such as 'press-and-hold'.
 ● Send different HID usages depending on the state of another control surface.

All HID usages sent from the keyboard shall occur in response to a Direct User Action (page 22).

Keyboards may integrate LEDs to indicate the:
 ● Caps Lock status of the device.
 ● Connection status, such as Bluetooth state.
 ● Battery status of the accessory, if applicable.

Keyboards shall not incorporate any other status LEDs not supported by devices.

Keyboards should be integrated with Trackpads (page 88) when possible to provide an enhanced user
experience.

Mechanical key layout shall be based on the ISO/IEC 9995-2, ANSI-INCITS 154-1988, or JIS X
6002-1980 standards. Keyboard HID descriptors shall set the Keyboard Physical Layout usage to the
appropriate layout code as defined in Table 14-5 (page 86).

Keyboard HID descriptors shall set the bCountryCode field to the appropriate country code as defined
in Device Class Definition for Human Interface Devices (HID) Version 1.11, section 6.2.1 HID Descriptor.

14. Keyboards

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

14. Keyboards

14.2 Examples

Devices may accept user input from accessory trackpads.

This feature is supported on iPadOS 14.5 or later.

15.1 Requirements
Accessory trackpads shall:

 ● Support the Human Interface Device (HID) (page 203) protocol.
 ● Not identify themselves as Apple-branded accessories, for example, using the Apple Vendor ID

(VID).

Accessory trackpads exhibiting any of the following behaviors are explicitly prohibited:
 ● Emulate combinations of touch gestures.
 ● Emulate timed user actions, such as 'click and hold', drag, and zoom gestures.
 ● Send different HID usages depending on the state of another control surface.

All HID reports sent from the accessory trackpad shall occur in response to a Direct User Action (page
22).

Trackpads shall support 2-5 simultaneous contacts on the digitizer surface.

15.1.1 Integration with Keyboards
Accessory trackpads shall be integrated with Keyboards (page 82) and simultaneously support both
input methods. The following are examples of interactions involving both keyboard and trackpad input:

 ● Rapidly transitioning between cursor movement and keyboard entry.
 ● Pressing and holding modifier keys while performing a drag.
 ● Pressing x-Tab to see the app switcher, then using the cursor to switch apps.
 ● Dragging an item using the trackpad, followed by pressing x-Tab to switch apps.

15.1.2 HID Report Descriptor
HID report descriptors for an accessory trackpad shall declare support for the HID Digitizer Page.

Accessory trackpads shall implement the following HID Digitizer page usages:

15.1.3 Coexistence
Accessory trackpads shall:

 ● Not degrade the performance of Multi-Touch or Apple Pencil.
 ● Not support a drive voltage greater than 6 Vpp.

 ● Not support drive frequencies less than 500 kHz.
 ● Support 3 or more drive frequencies, separated by at least 50 kHz each.
 ● Dynamically switch between drive frequencies whenever effective resolution drops below 120 DPI.

For example, effective resolution may drop in the presence of 50 mV RMS noise from external
power sources.

Accessory trackpads should support a sine wave narrow band drive frequency.

15.1.4 Performance
Accessory trackpads shall:

15. Trackpads

15.1 Requirements

 ● Behave uniformly across the digitizer surface.
 ● Uniquely detect contact points as close as 8 mm center to center.
 ● Detect contact sizes of at least 5 mm.
 ● Differentiate between multi-finger taps and single-finger drags.
 ● Maintain an effective input resolution less than 20 µm and immediately report positional updates

greater than or equal to the effective input resolution.
 ● Maintain an effective resolution more than 600 DPI.
 ● Maintain the highest possible report rate to the device. Apple recommends 60 Hz or higher.
 ● Maintain a panning latency less than or equal to 23 ms.
 ● Maintain a touch down latency less than or equal to 35 ms.
 ● Maintain a positional accuracy less than or equal to 500 µm.
 ● Maintain a stationary contact jitter less than or equal to 210 µm.
 ● Not deviate more than 250 µm from an ideal line.

15.1.5 Input Confidence
Accessory trackpads shall:

 ● Set the Confidence usage when an input transitions from valid to invalid. Contact transitions should
be quick, accurate, and stable to achieve the best user experience. Incorrect or fluctuating
classification of contacts may result in recognition of unintended gestures, interruption, or cancelation
of intended gestures.

 ● Detect and reject unintended/invalid inputs, such as palms, while continuing to report valid inputs
to the device, such as multiple contacts.

 ● Distinguish between a valid large thumb and an invalid lightly resting palm.
 ● Reject inputs ≥1 mm from the tracking surface.

15.1.6 Click to Wake
Devices use Report ID usage to indicate to the trackpad whether surface contacts shall be reported or
not. Devices will use the Surface Switch usage to tell the accessory to go into Click to Wake mode
where only button clicks are accepted. Trackpads may use this opportunity to go into a low power
mode where the digitizer surface does not have to be constantly scanned.

This feature report also doubles as an informational report. Devices may query the accessory trackpad
at any time after enumeration to obtain the current state of the Surface Switch, and also to get the
accessory's Report Rate.

15.2 Examples

15.2.1 Example HID Report Descriptor
The following descriptor is for a 92.10 mm x 50.60 mm trackpad with two buttons supporting up to
five simultaneous contacts.

Additional modifications may be necessary in order to implement this HID report descriptor in the
accessory trackpad firmware, specifically:

 ● Modify physical maximum values for X (0x30) and Y (0x31) positions of each finger to match the
physical size of the accessory trackpad. Units are in tenths of a mm (0.1 mm). In the example, X
goes from 0x0 to 0x0399 (92.10 mm) and Y goes from 0x0 to 0x01FA (50.60 mm).

 ● Modify logical maximum values for the X (0x30) and Y (0x31) of each finger positions to match
the resolution of the accessory trackpad. In the example, X (0x30) goes from 0 to 0x0451 (for a
resolution of 92.10/1105 = ~0.083 mm) and Y (0x31) goes from 0 to 0x025F (for the same
resolution of 50.60/607 = ~0.083 mm).

17.3 Test Procedures

A well-designed watch band will securely attach to Apple Watch without interfering with Apple Watch
operation. See Device Dimensional Drawings (page 253) for Apple Watch dimensional drawings with
defined keep-out zones.

18.1 Requirements
Watch bands for Apple Watch shall integrate two lugs to mate with the Apple Watch Band Interface
(page 103). Apple Watch uses a high precision interface profile, see https://developer.apple.com/acces-
sories/apple-watch-lug-profile.zip for a sample 2D lug profile. Lugs should lock into the watch band
mating slot with a 'lug latch' feature to prevent accidental removal of the watch band.

Exposed edges of watch bands and lugs shall pass UL 1439 tests for sharpness of edges on equipment
and BS EN 71-1:2014, Safety of Toys - Mechanical and physical properties.

The lug latch shall never become jammed in the extended position.

Watch bands shall not integrate magnetic chargers.

Watch bands and lugs should:
 ● Pass a 72 hour salt mist test as specified in ASTM B117 with no visible corrosion.
 ● Resist a 5-20 kgf lateral slide-out force when installed in Apple Watch.
 ● Resist a 20 kgf or greater pull force as specified in ISO-6245:1996, Specifications for Diver's

Watches, section 7.3.
 ● Detach easily from Apple Watch when the watch band release buttons are pressed.
 ● Take into account the weight of Apple Watch.

Watch bands shall enable the user to maintain direct skin contact with Apple Watch heart sensors and
the back of Apple Watch, and shall incorporate sufficient margin to compensate for shifting or
dimensional changes of the watch band material. Failure to do so may interfere with Apple Watch wrist
detect and Apple Pay features. Watch bands should:

 ● Have length sizing adjustment pitch of less than 7 mm (center to center).
 ● Provide sufficient adjustability for the user to achieve a snug, yet comfortable fit preventing

movement of Apple Watch relative to the wearer's skin.

18.3 Example Apple Watch Lug Assembly
Assembly instructions are based on Example Apple Watch Lug (page 106) and an assembly fixture with
a clamping mechanism.

Proper assembly of the lug is critical to ensure the watch band securely attaches to Apple Watch.
Improper assembly may result in damage to Apple Watch and/or the watch band.

Screw threads should be secured with Loctite 435. Previously installed/used screws should not be
reused.

The assembly fixture should hold the lug assembly in place and a clamping mechanism should compress
the lug during screw insertion.

Assemble the watch band and lug as follows, see Figure 18-1 (page 105).

1. Lightly insert the long end of the female pin in the watch band until hard stop. Ensure there is no
warping or damage in the watch band.

2. Lightly insert the long end of the male pin in the other side of the band until it interlocks with the
female pin and both pins are seated together. Ensure there is no warping or damage in the watch
band.

3. Align the holes on the bottom of the lug with the exposed ends of the female and male pins. Note
lug latch top/bottom orientation relative to the watch band. Latch shall be on the side of the watch
band against the wrist.

4. Apply Loctite 435 to screw threads.
5. Install both screws using the following specification:

 ● Torque: 1.1 kgf-cm ±10%
 ● RPM: 120 ±10%

6. Visually inspect at 1200-1400 lux for screw proudness and cross-threading.
7. Ensure screws are just sub-flush to the lowest part of the counterbore and appear parallel to the

long axis of the lug.
8. Ensure screws are undamaged, flat, and concentric with the counterbore.

Apple recommends shielding the magnetic field from the charging coil and maintaining a low impedance
shield termination for cables to comply with regulatory EMC requirements for the completed product.
Implementation, final compliance testing, report preparation, and labeling are the responsibilities of
the company marketing and producing the product.

Cable termination is critical for reduced emissions. Cable termination and connectors should be kept
away from the charging coil and cables should be routed away from the charging surface.

If emissions are present, adding clamp-on ferrites/absorbers to the cable can help reduce emissions.
Selected ferrite/absorber materials should be rated for the failing frequencies.

Depending on the accessory's supported use cases, testing should be performed with the following
power supplies:

 ● Apple USB-C Power Adapters:
 ● Apple 140W USB-C Power Adapter
 ● Apple 96W USB-C Power Adapter
 ● Apple 70W USB-C Power Adapter
 ● Apple 67W USB-C Power Adapter
 ● Apple 30W USB-C Power Adapter
 ● Apple 20W USB-C Power Adapter
 ● Apple 35W Dual USB-C Port Compact Power Adapter
 ● Apple 35W Dual USB-C Port Power Adapter

 ● Apple USB-A Power Adapters:
 ● Apple 12W USB Power Adapter
 ● Apple 5W USB Power Adapter

 ● Model A1385 (US)
 ● Model A1400 (Int.)
 ● Model A1552 (UK)
 ● Model A1443 (China)

the Apple MFi Licensing Program (page 23).

39.1 Enabling Custom Siri Commands
Accessories supporting Siri over Bluetooth using HFP commands shall support HFP Command AT+XAPL
(page 119). The device will use the information sent by this command to enable and disable custom
commands related to Siri.

To receive Siri status events, the accessory shall send the AT+XAPL command after making a successful
HFP Service Level Connection (SLC) to the device. The accessory should send an AT+XAPL command
first, before sending any of the additional Siri-specific commands described below.

39.2 Obtaining Siri Availability Information
After establishing an HFP profile connection, an accessory can determine if Siri is available and enabled
on a device. It can also receive notifications of changes in Siri status. If Siri is disabled, Voice Control
will be activated instead.

39.2.1 Obtaining Status Information at Connection
The accessory should send the following command after making a successful HFP profile (SLC)
connection and sending an AT+XAPL command.

39.2.1.1 HFP Command AT+APLSIRI?

39.3 Initiating a Siri Session
Once support for Siri is established on both the accessory and the device, a Siri session can be started
from either one.

39.3.1 Initiating a Session from the Accessory
The accessory should only initiate a Siri session as a result of a direct user action.

The accessory shall use the voice recognition command AT+BVRA defined in the Bluetooth Hands-Free
Profile specification (Hands-Free Profile 1.6 profile specification, section 4.25) to initiate a Siri session.

The HFP profile shall be connected and SLC shall exist.

The accessory should use the following command sequence:
 ● The accessory sends an AT+BVRA=1 command to the device.
 ● The device sends an OK response.
 ● The device activates a Siri session and creates a Synchronous Connection (SCO) for the audio.
 ● If the Siri session is not finished, the accessory shall send AT+BVRA=1 to continue the conversation.

This may need to happen multiple times.
 ● When the Siri session is finished, the device sends a +BVRA:0 result code to the accessory.
 ● The device disconnects the SCO connection.

While a Siri session is active, the accessory shall let the user continue the conversation and ask follow
up questions within the current context. In order to do so, the accessory shall be able to send an
AT+BVRA=1 command to the device even after Siri has been already activated and before +BVRA:0

its feature response as described in the Bluetooth Hands-Free Profile 1.6 specification, section 4.34.1,
"Bluetooth Defined AT Capabilities." Specifically, the HFP profile shall be connected, SLC shall exist,
and voice recognition activation (bit 3) shall be enabled in the AT+BRSF command. The device will not
use virtual call functionality for the Siri session if voice recognition activation is supported by the
accessory.

The accessory should expect the following command sequence:
 ● The device sends a +BVRA:1 event to the accessory.
 ● The device activates a Siri session and creates a SCO connection for the audio.
 ● When the Siri session is finished, the device sends a +BVRA:0 result code to the accessory.
 ● The device disconnects the SCO connection.

look at a screen. Siri Eyes Free mode is supported only for Bluetooth-enabled vehicle entertainment
systems and should not be used by any other accessories. Siri Eyes Free should not be triggered using
a voice command.

The device will listen for the HFP AT command AT+APLEFM to enable or disable Siri Eyes Free mode.

This command is used by the device to modify Siri responses containing visual information or requiring
user interaction. Suitable audio feedback and voice commands will be available to the user based on
the initiated Siri use case.

Siri Eyes Free mode is disabled by default. Once the accessory has enabled Siri Eyes Free mode, it
remains enabled for all subsequent Siri sessions initiated from the accessory until the accessory disables
it or the Bluetooth connection is disconnected.

39.4.1 HFP Command AT+APLEFM
Description: An accessory sends this command to notify a device of the preferred state of Siri Eyes
Free mode.

Initiator: Accessory

Format: AT+APLEFM=value

Response: OK

Defined Values:
 ● 0x00 = Disable Siri Eyes Free mode.
 ● 0x01 = Enable Siri Eyes Free mode.
 ● 0x02-0xFF = reserved

Example: AT+APLEFM=1

39.5 Improving Voice Recognition
The microphone audio an accessory sends to the device during a Siri session should be suitable for
voice recognition. Audio requirements for optimal voice recognition may differ from requirements for
optimal human perception (for example, during a cellular phone call).

Filtering of the audio signal to remove echoes or feedback noise is acceptable.

To provide the best possible audio quality as Siri input, the accessory shall observe the following
recommendations:

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

178

39. Siri

39.5 Improving Voice Recognition

 ● Echo cancellation and noise suppression (EC/NR): Directional microphones and linear
beamforming with microphone arrays giving improved SNR are recommended. Linear echo
cancellation for reducing unwanted audio sources (such as audio output from the system) without
having any other effect on the speech signal are also recommended. However, single channel noise
reduction methods (such as spectrum subtraction) shall not be applied, as they will be detrimental
to the speech recognition accuracy. Similarly, automatic gain control, residual echo suppression
and attempts to blank out non-speech periods in the waveform shall not be applied.

 ● Signal gain: When adjusting signal levels, the accessory shall avoid artifacts, dropouts, and clipping
in all circumstances. Automatic Gain Control is not recommended. If the accessory adjusts signal
gain, the gain should be held constant across each spoken utterance. The nominal level measured
at the uplink output of the accessory should be A-weighted -30 dB ±2 dB root-mean-square (RMS),
expressed in units relative to full-scale (dBFS(A)). Alternatively, the nominal level may be 13 dB ±2
dB SLR if using the ITU measurement procedure.

 ● Signal-to-noise ratio (SNR): The average SNR should be greater than 20 dB. Below 20 dB,
recognition rates will be impacted.

 ● Reverberation: An RT60 time less than 200 ms should be maintained.

39.5.1 Wide Band Speech Support
An accessory using Siri should support 16 kHz wide band speech audio for better audio quality and
voice recognition performance. See the Bluetooth Hands-Free Profile 1.6 specification for details about
wide band speech audio. Narrow band audio signal (8 kHz) is supported but not recommended.

39.6 Optimizing the Siri Experience
The start of a Siri session should not be accompanied by local beeps or verbal indications (such as an
announcement of "...voice dialing...") from the accessory. When a Siri session becomes active, the
device sends two beeps indicating that Siri is ready to receive instructions. Adding extra audible
notifications only inserts delays in the system.

The accessory should wait for the device to end each Siri session.

The accessory should not send an AT+BVRA=0 command unless it is prompted to do so by user
interaction.

The accessory should be capable of rendering audio within 200 ms of SCO connection activation to
ensure that the user always hears the Siri introductory beeps.

39.6 Optimizing the Siri Experience

39.7 Common Siri Applications
Siri can send messages, find points of interests, place phone calls, and much more. As Siri capabilities
are constantly growing, additional use cases may become available after the initial integration. In Siri
Eyes Free mode, some of these use cases may not be accessible as the user experience is tailored
towards a driving scenario.

39.7.1 Initialization Procedure After Connection is Established
Figure 39-5 (page 180) outlines the sequence the accessory has to trigger to be able to use Siri on a
device. After establishing an HFP profile connection, the accessory shall first enable the custom Siri
commands by sending AT+XAPL and provide the features it supports. After a confirmation is received
from the device, the accessory should determine Siri's availability with AT+APLSIRI?.

Vehicles with Bluetooth-enabled infotainment systems can also enable Siri Eyes Free Mode during
initialization. This is detailed in Figure 39-6 (page 181).

39.7.2 Phone Dialing Using Siri
Upon user request, Siri can initiate an outgoing phone call. The device will initiate HFP call signaling to
establish a phone call as described in Bluetooth (page 207). The accessory shall be able to transition
to Hands-Free dialing at any time during or after a Siri session when signaled by the device.

39.7.3 Audio Routing and Media Playback Using Siri
Siri can control the media playback on a device, and if Siri determines the user wants to play or pause
music, Siri will either start, pause or resume media playback. The device will send a notification to the
accessory indicating a change in playback state and any associated track information. The accessory
shall respond to the notifications, start or stop the music playback as requested, as well as update the
correct playback state (for example, shuffle, repeat).

The accessory shall not force a change in the playback state after a Siri session is ended. If music was
playing before Siri was started, it shall continue playing, if it was paused, it shall remain paused.

After Siri starts music playback the accessory shall set its current audio route to match the audio source,
depending on how audio is being received from the device (using Bluetooth or by a wired connection).

The available media playback notifications depend on the audio route being used:
 ● Bluetooth audio routes shall use the approach described in Notifications (page 214) and Audio Data

Received using A2DP Profile (page 217).
 ● Wired audio routes shall use iAP2.

39.7 Common Siri Applications

39.7.4 Turn-By-Turn Directions Using Siri
Siri can initiate active route guidance to provide turn-by-turn directions. In case the device is the active
source and is already playing music, turn-by-turn directions will be mixed in as part of the audio stream.
In case the device is not playing music, the accessory should be able to mix in turn-by-turn directions
with the active audio source.

The device will notify the accessory to play turn-by-turn directions only over Bluetooth. Detailed
information on how to distinguish between music playback and turn-by-turn notifications is available
in Notifications (page 214).

39.8 User Interaction with Siri Eyes Free in a Vehicle
A vehicle using Siri Eyes Free mode shall integrate the Siri experience with the existing in-vehicle
entertainment system and controls. The vehicle should provide a convenient interface to initiate,
continue, and end a Siri session. Once a Siri session is running, the vehicle shall display a visual cue
indicating voice recognition is in use. Figure 39-7 (page 183) outlines how a Siri interaction should be
designed.

39.8 User Interaction with Siri Eyes Free in a Vehicle

When a vehicle enables Siri Eyes Free mode, the device will not display any onscreen Siri content. If
the device was locked at the time the Siri session was activated from the vehicle, it will remain locked
and the screen will not turn on. If the user unlocks or manually activates the device while in an Eyes
Free Session there will be a notification the device is in an active Siri session but there will be no visual
Siri content displayed.

39.9 Enabling/Disabling Siri from the Device
The user has the ability to disable or enable Siri from the Settings menu on the device. When Siri is
disabled, Voice Control becomes the recognition engine on the device and will be triggered by default.
The accessory may choose to either:

 ● Activate Voice Control (in the same way Siri is activated) as in Figure 39-8 (page 184).
 ● Display a warning message and not send an activation command to the device as in Figure 39-9

The resistor network shall be connected at all times unless the accessory uses one of the following
methods to enable charging or detect the presence of a device. In these cases, it shall immediately
present the resistor network. The accessory:

 ● Uses a direct user action to enable charging.
 ● Senses the attachment of the device using electromechanical means such as a contact switch.

The accessory shall not monitor the USB D+ and USB D- pins to detect the presence of a device.

All resistors used to implement the networks specified in Figure 42-1 (page 193) shall have a tolerance
of 1% or better. The resistor network shall not be emulated by driving the voltage of the USB D+/D-
pins using some other means.

42.2 Identifying Power Source Current Limit
Accessories shall take into account the variation of USB VBUS voltage and resistor tolerances.

The resistor network values and corresponding current source limits should be identified using the
following procedures:
1. Read the VBUS voltage using an ADC. If value is less than 4.5 V, return no resistors detected.
2. Pull-down the D+ and D- lines and read the voltage using an ADC. If either voltage value is less

than 1 V, return no resistors detected.
3. Disable the D+ and D- pull-downs and allow the voltage to return to normal.
4. Read the D+ and D- voltages using an ADC (to determine the value for R1 and R3 respectively):

 ● If voltage is >2.995 V (based on 1 MΩ load impedance), assume a resistor value of 24.9 kΩ.
 ● If voltage is between 2.320 V and 2.995 V (based on 1 MΩ load impedance), assume a resistor

value of 43.2 kΩ.
 ● If voltage is < 2.320 V (based on 1 MΩ load impedance), assume a resistor value of 75.0 kΩ.

5. Determine the max current based on Table 42-2 (page 195).

Accessories may implement the Advanced Audio Distribution Profile (A2DP) over Bluetooth (page 207)
to receive audio from iOS devices and Mac computers.

The audio content from the device can be broadly classified into two categories:
 ● Audio content from music, video, or gaming applications.
 ● System-generated sounds for alerts and notifications.

A2DP is often implemented in speakers and headsets.

Accessories implementing A2DP shall satisfy all requirements stated in Bluetooth (page 207).

45.1 Bluetooth A2DP Specification
Accessories implementing the Advanced Audio Distribution Profile shall meet the requirements of the
Bluetooth Advanced Audio Distribution Profile specification, Version 1.2.

45.1.1 AVDTP Transactions
Accessories shall respond to Audio/Video Distribution Transport Protocol (AVDTP) signaling transactions
before the device's 5 second RTX_SIG_TIMER expires or the device will terminate the signaling channel.
See Section 6.2 "Transaction Model" and section 6.4 "Signal Command Set" of the Bluetooth
Audio/Video Distribution Transport Protocol, Version 1.3.

shown in Table 45-3 (page 199).

 ● The recommended L2CAP MTU value for each device's AAC streaming channel is 885 bytes.
 ● The AVDTP Header is shown as the RTP header in Figure 4 of RFC 3016, and is the header defined

in Section 7.2.1 of the Bluetooth Audio/Video Distribution Transport Protocol, Version 1.2.
 ● The AudioMuxElement is the same as the RTP payload in RFC 3016. It is defined in Section 1.7.3,

Table 1.41 in ISO/IEC 14496-3:2009, subpart 1. The muxConfigPresent argument to the
AudioMuxElement is set to 1 (in-band mode), as recommended in Section 4.1 of RFC 3016. As
recommended in Section 4.3 of RFC 3016, only one AudioMuxElement is put into each AVDTP
packet.

 ● The audio payload is encoded using MPEG-4, as recommended in Section 4.5.4 of the A2DP
specification.

 ● The accessory should support AAC-LC VBR and handle bit rate changes without audio gaps.
Devices will vary AAC bit rate depending on the content.

Devices can accept input from and send output to Human Interface Device (HID) accessories, such as
external keyboards, trackpads, mice, and game controllers. This capability is made available system-wide
for all apps on the device as well as to support features built into iOS, iPadOS, and tvOS. If an accessory
is designed to provide human input events to a specific third-party app, the accessory should use the
External Accessory Protocol feature instead; see the Accessory Interface Specification (page 23) for
more information.

The HID protocol can be implemented over:
 ● USB
 ● Bluetooth

47.1 Requirements
Accessories supporting the HID protocol shall comply with the following requirements:

 ● Accessories shall only send HID reports for changes in physical or virtual control surfaces declared
in the corresponding HID descriptor.

 ● Accessories shall not send a HID report if there has not been any change in the state of the
corresponding physical or virtual control surface. For example, the accessory shall never generate
a "Play/Pause" event without the user pressing a dedicated "Play/Pause" button.

 ● Each HID report shall contain the correct number of bytes as described in its corresponding HID
descriptor.

 ● The accessory shall not anticipate or assume corresponding state changes in the device after
sending HID reports.

 ● Unless otherwise specified:
 ● The accessory shall be capable of generating and receiving all HID usages declared in its HID

descriptor.
 ● The accessory's declared HID usages shall map directly to physical or virtual control surfaces

on a 1:1 basis. For example, a button labeled "Play/Pause" shall send a Play/Pause HID usage
and not "Play" or "Pause" usages. Compound controls such as knobs, joysticks, and directional
pads may be considered multiple control surfaces. For example, clockwise and counterclockwise
rotation may map to separate HID usages.

47. Human Interface Device (HID)

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

203

 ● Physical or virtual control surfaces generating HID reports shall be labeled with appropriate
iconography or text corresponding to the resulting device behavior. For example, a Play/Pause
button shall be labeled with the text 'Play/Pause' or a Play/Pause icon.

 ● The accessory shall send one HID report in response to each direct user action on the
corresponding physical or virtual control surface. For example:

 ● When the user presses a button, one 'button pressed' HID report shall be sent to the device.
 ● When the user releases the button, one 'button released' HID report shall be sent to the

device.

47.1.1 Report Descriptor
When padding packets to align within a byte boundary, each Main item tag (Input, Output, or Feature)
shall be marked constant. Padding bits should be set to 0.

When defining Variable type Input/Output fields, either:
 ● Report Count number shall correspond to the number of Usages specified.
 ● Report Size shall be 8 and the Report Count shall correspond to the size of a multi-byte blob.

47.1.2 USB
If implementing HID over USB, the accessory shall comply with the Device Class Definition for Human
Interface Devices 1.11, see https://www.usb.org/hid.

47.2 Test Procedures

47.2.1 General
1. Verify the accessory generates and receives all HID usages declared in the component's HID

descriptor.
2. Verify the accessory does not send a HID report if there has not been any change in the state of

the control surfaces (that is, no polling of HID reports).
3. Verify if any accessory has physical or virtual control surfaces generating accessory HID usages,

the controls are labeled with appropriate iconography or text corresponding to the resulting device
behavior (for example, a Play/Pause button is labeled with the text "Play/Pause" or a Play/Pause
icon).

4. Verify HID usages map to physical or virtual controls on a 1:1 basis (for example, Play button only
sends Play usages, not Play/Pause).

47.2 Test Procedures

Transports

Accessories integrating Bluetooth technology shall comply with the requirements stated in this chapter.

Accessories shall support the Bluetooth Core Specification Version 2.1 + EDR or later.

48.1 Enhanced Data Rate
The Enhanced Data Rate (EDR) feature introduced in the Bluetooth 2.0 specification enables accessories
to communicate more efficiently. Accessories shall use EDR for the following reasons:

 ● EDR provides higher data rates compared to Basic Data Rate (BDR).
 ● EDR communicates more efficiently, transferring more data bits in less time.
 ● EDR reduces power consumption per bit transferred.
 ● EDR improves coexistence with Wi-Fi and other Bluetooth accessories by using less airtime.
 ● EDR improves performance in multipoint configurations.

48.2 Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) introduced in the Bluetooth 1.2 specification improves coexistence
with Wi-Fi and other connected Bluetooth accessories. Accessories shall use AFH.

48.3 Sniff Mode for Low Power Consumption
Minimizing power consumption is critical for all mobile devices, therefore accessories:

 ● Shall support and should request Bluetooth sniff mode.
 ● Shall accept sniff mode requests and support valid parameters from the Bluetooth specification.
 ● Shall support a sniff interval of 15 ms.
 ● Shall support sniff subrating.
 ● Shall not renegotiate sniff mode after it is established.
 ● Should use sniff mode values of:

 ● Max Interval: 15 ms
 ● Min Interval: 15 ms
 ● Sniff Attempt: 1

48. Bluetooth

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

207

 ● Sniff Timeout: 0

Accessories compatible with iOS devices and Mac computers should use sniff mode as often as possible,
especially when there is little or no data being transmitted over the Bluetooth link. Sniff mode enables
better antenna sharing with Wi-Fi, in addition to the power consumption advantages.

Sniff mode parameters are specific to the usage model and Bluetooth profile. Accessories should
request sniff mode with appropriate parameters for specific usage models. If the accessory does not
send a sniff mode request, the device may send a sniff mode request. When the device sends a sniff
mode request, the accessory shall accept the request and parameters without negotiation.

If the accessory requests sniff mode, the accessory shall set the sniff interval to less than a third of
the Bluetooth baseband Link Supervision Timeout (page 210), to make the Bluetooth link less susceptible
to interference. To improve link robustness, the accessory should use a shorter sniff interval instead
of multiple sniff attempts.

Links with a sniff interval of 1 second or more require a large correlation window, which has to be taken
into account when calculating the number of sniff attempts. With sniff intervals shorter than 1 second,
multiple sniff attempts can improve link robustness, but will increase power consumption.

48.4 Role and Topology Management
Accessories shall:

 ● Accept device Role Switch requests.
 ● Continue with the connection when the device rejects a request for Role Switch.

In a Bluetooth connection, there are two entities:
 ● The Central entity establishes a common clock and frequency hopping synchronization reference.
 ● The Peripheral entity synchronizes with the Central entity.

The Central entity can be synchronized with multiple Peripheral entities, thus forming a piconet. The
Central entity can also be a Peripheral entity to another Central entity, creating a scatternet.

Accessories simultaneously connecting to multiple iOS devices or Mac computers shall support creating
a scatternet.

Scatternets create complications since the device has to alternate between piconets, wasting valuable
bandwidth. Efficiently managing network topology is important to maximize performance. The device
may request a Role Switch, depending on its current topology, and the accessory shall accept the
request. The device may also reject a Role Switch request due to topology concerns, as suboptimal
topologies may degrade audio quality and the user experience.

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

208

48. Bluetooth

48.4 Role and Topology Management

Accessories should avoid requesting to be the Central entity, as in more frequently occurring scenarios
the device needs to be the Central entity. Accessories insisting on being the Central entity may negatively
impact the overall user experience.

48.5 Extended Inquiry Response
Accessories shall provide the following information in their Extended Inquiry Response packet:

 ● Local Name of the accessory (Complete or Shortened).
 ● TX Power Level.

During Bluetooth discovery, devices display accessories Friendly Names when available. Extended
Inquiry Response enables accessories to proactively send their Local Name, and other information, as
part of an Inquiry Response to increase the speed and efficiency of the discovery process.

Accessory Local Name should match the accessory's labeling and packaging without colons ':' or
semi-colons ';'. Accessories may append up to six differentiating characters to their Local Name, such
as the last few digits of a serial number or MAC address, if users are likely to encounter multiple
accessories at the same time using the same name. If the accessory allows a user to customize the
Local Name parameter, the accessory should provide a means to restore the factory default name.

48.6 Secure Simple Pairing
Accessories shall:

 ● Use Secure Simple Pairing.
 ● Use the Numerical Comparison method, if it has a display and input device supporting it.

Secure Simple Pairing greatly increases security, and is a mandatory security feature in the Bluetooth
2.1 specification. To protect against a 'man-in-the-middle' attack, the Numerical Comparison association
model should be used whenever feasible. See Volume 1, Section 5.4 in the Bluetooth Core Specification,
Version 2.1 + EDR.

48.7 Pairing Button
If the accessory has a labeled dedicated pairing control, it should use official Bluetooth branding. See
https://www.bluetooth.com/develop-with-bluetooth/marketing-branding/.

https://www.bluetooth.com/develop-with-bluetooth/marketing-branding/

48.8 Class of Device (CoD)
iOS devices and Mac computers use the accessory's Class of Device for UI purposes or to configure
specific features. Accessories shall accurately set their Class of Device using the Bluetooth SIG defined
Major Device Class and Minor Device Class. See Volume 3, Part C, Section 3.2.4 in the Bluetooth Core
Specification, Version 5.0. For example, an audio/video accessory intended to operate in a vehicle
should set Major Device Class to 'audio/video' and Minor Device Class to 'car-audio'.

48.9 Link Supervision Timeout
Link supervision timeout is used to detect link loss between an accessory and a device. An accessory
shall set the link supervision timeout to 2 seconds or greater when it is the Central entity, to account
for the unpredictable nature of RF signals, as well as the device's need to service other concurrent
wireless systems.

48.10 Delay Reporting
As of iOS 8.2, devices support Delay Reporting commands as specified in the Bluetooth Audio/Video
Distribution Transport Protocol, Version 1.3. Accessories should provide this information to improve
audio/video synchronization for video playback. Accessories should not report a delay of more than
1000 ms, and should not update the delay more than 1 time per second.

48.11 Profiles
The Apple Bluetooth profiles knowledge base article https://support.apple.com/kb/ht3647 provides a
complete list of the profiles supported by devices. Bluetooth specifications are the starting point for
designing accessories compatible with these devices. The following sections provide additional
information and requirements for common profiles to help accessory developers achieve superior
results.

48.11.1 Device ID Profile (DID)
Accessories shall:

 ● Support Bluetooth Device ID Profile, Version 1.3 or later.

210

48. Bluetooth

48.8 Class of Device (CoD)

https://support.apple.com/kb/ht3647

 ● Use their Company Identifier from the Assigned Numbers specification assigned by the Bluetooth
SIG as the Vendor ID value (VID), see https://www.bluetooth.com/specifications/assigned-numbers/.
Bluetooth HID Profile accessories may use a VID assigned by the USB Implementers Forum (USB-IF),
see https://www.usb.org/getting-vendor-id, if the manufacturer does not have a Bluetooth SIG
Company Identifier.

 ● Use its VID value for the end product manufacturer.
 ● Not use the Company ID assigned to Apple by the Bluetooth SIG, or the Vendor ID assigned to

Apple by the USB Implementers Forum.
 ● Use the Vendor ID Source field to identify which organization assigned the value used in the Vendor

ID field. See Section 5.6 of the Bluetooth Device ID Profile Specification.
 ● Use a ProductID value uniquely identifying the product.
 ● Use a Version value uniquely identifying the software version.

The Device ID record enables devices to identify the implementation of the remote accessory, which
is used to bridge alternate interpretations of the Bluetooth specification when communicating with a
remote accessory. It is important the information in the Device ID record uniquely identify the
implementation in use.

In the case of Bluetooth car kit devices, the same car kit may be present in different car models. Ideally,
the two car kits should have different ProductIDs. However, it is acceptable for them to have the same
ProductID as long as they have identical hardware, software, and features. If the implementations differ
at all, they should have different ProductIDs. The accessory can also use a secondary Device ID record
to uniquely identify the product ID, or model number.

48.11.2 Service Discovery Protocol (SDP)
To facilitate caching Service Discovery Protocol service records, accessories shall:

 ● Support the ServiceDiscoveryServer Service Class.
 ● Support the ServiceDatabaseState attribute.

 ● Attribute's value shall change whenever any SDP service record or attributes within a record
are added, removed, or modified.

 ● Attribute's value shall not change based on RFCOMM channel protocol parameters. Devices
query these values separately at connection time.

48.11.3 Hands-Free Profile (HFP)
Accessories supporting Hands-Free Profile should meet the requirements of the Bluetooth Hands-Free
Profile Specification, Version 1.5 or later. Additional Apple requirements are specified in this section.

Remote accessories can use the Bluetooth Hands-Free Profile for phone communications. To achieve
the best user experience, the remote accessory should support the following features, which are
optional in the Bluetooth specification.

211

48. Bluetooth

48.11 Profiles

https://www.bluetooth.com/specifications/assigned-numbers/

https://www.usb.org/getting-vendor-id

48.11.3.1 Remote Audio Volume Control
Accessories supporting HFP should:

 ● Support Remote Audio Volume Control, so speaker volume on the hands-free accessory can be
controlled from the device as described in Section 4.28 in the Bluetooth Hands-Free Profile
Specification, Version 1.5.

 ● Set the Remote volume control bit in the Supported Features bitmap sent with the AT+BRSF=
command.

In some situations it is easier for the user to control the output volume through the device, instead of
directly on the remote accessory. For example, a car passenger (or if the car is parked, the driver) could
use the volume slider on the phone to control audio volume. Volume control synchronization is outlined
in Section 4.48.2 in the Bluetooth Hands-Free Profile Specification, Version 1.5.

48.11.3.2 Indicator Event Reporting
Accessories supporting HFP should use Indicator Event Reporting, and not perform repetitive status
polling.

iOS devices and Mac computers support all mandatory and optional indicators specified in HFP version
1.5 (service, call, callsetup, callheld, signal, roam, battchg). To minimize unnecessary
status polling using the AT+CIND? command, the remote accessory should enable Indicator Event
Reporting by sending an AT+CMER command. The device will then send a +CIEV event when there is
a status change. The remote accessory should request initial status using the AT+CIND=? and
AT+CIND? commands, according to the HFP specification.

48.11.3.3 Voice Recognition Activation
Accessories supporting HFP shall:

 ● Support Voice Recognition Activation, both AG and HF, initiated as described in Section 4.25 in
the Bluetooth Hands-Free Profile Specification, Version 1.5.

 ● Set the Voice Recognition Activation bit in the "SupportedFeatures" bitmap sent with the AT+BRSF=
command.

iOS devices and Mac computers support voice recognition initiated by remote (Hands-Free) accessories,
and iOS (Audio Gateway) accessories.

48.11.3.4 Echo Cancellation and Noise Reduction
When echo cancellation and noise reduction are performed locally on a hands-free accessory, the
accessory should turn off echo cancellation and noise reduction on the device by sending an AT+NREC
command, as described in Section 4.24 in the Bluetooth Hands-Free Profile Specification, Version 1.5.

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

212

48. Bluetooth

48.11 Profiles

iOS devices and Mac computers support echo cancellation and noise reduction by default. If a hands-free
accessory performs echo cancellation and noise reduction, the accessory needs to turn these features
off on the device (the Audio Gateway), to avoid unnecessary audio quality degradation due to duplicate
audio processing.

48.11.3.5 In-Band Ringing
Accessories supporting HFP should also support In-Band Ringing as specified in Section 4.13.1 in the
Bluetooth Hands-Free Profile Specification, Version 1.5. If the user sets a ring tone on the device, the
same ring tone should sound on the hands-free accessory.

48.11.3.6 Synchronous Connection
Accessories supporting HFP shall:

 ● Support eSCO parameter set S2 and S3 and accept requests for these settings. See Section 5.6
of the Bluetooth Hands-Free Profile Specification version 1.5.

 ● Request eSCO parameter set S2 or S3 when setting up a Synchronous Connection. eSCO parameter
set S1 should not be requested.

 ● Render audio within 40 ms after the SCO/eSCO connection has been set up.

eSCO packet types offer packet retransmission, whereas traditional SCO packets are not retransmitted.
This improves audio quality and the user experience. eSCO packet types 2-EV3 and 3-EV3 offer a
greater time interval between packets, which can improve Wi-Fi performance and allow time for other
concurrent Bluetooth connections to send data.

Apple strongly recommends the use of 2-EV3 and 3-EV3 packets for SCO connections. Using HV3
packets is highly discouraged. HV3 packets require more link time and do not allow audio packet
retransmission, which impacts audio performance in the presence of RF interference.

48.11.3.7 Wide Band Speech
Accessories supporting HFP should support Wide Band Speech, as described in Section 5.7.4 of the
Bluetooth Hands-Free Profile Specification, Version 1.6. If Wide Band Speech is supported, the accessory
should support the T2 link parameter settings.

Devices running iOS 5 or later support Wide Band Speech. If both the device and the accessory support
Wide Band Speech, the device will use it for eSCO connection scenarios such as cellular calls, FaceTime,
and Siri.

48.11.4 Message Access Profile (MAP)
Accessories supporting Message Access Profile:

 ● Shall register for notifications immediately after the connection is established, as described in
Section 4.5 in the Message Access Profile Specification, Version 1.1.

Devices running iOS 13.0 or later support MAP 1.1.

48.11.5 Audio/Video Remote Control Profile (AVRCP)
Accessories supporting Audio/Video Remote Control Profile should meet the requirements of the
Bluetooth Audio/Video Remote Control Profile Specification, Version 1.4. Additional Apple requirements
are specified in this section.

48.11.5.1 Supported Operations
iOS devices and Mac computers support the following operation_IDs in passthrough commands:

 ● Play
 ● Stop
 ● Pause
 ● Fast Forward
 ● Rewind
 ● Forward
 ● Backward

48.11.5.2 Repeat and Shuffle Modes
Every device in the role of an AVRCP target supports Repeat and Shuffle modes. An AVRCP controller
may use SetPlayerApplicationSettingValue to set a value on the device and
GetPlayerApplicationSettingValue to read a value, as described in Sections 6.5.4 and 6.4.3
of the Bluetooth Audio/Video Remote Control Profile Specification, Version 1.4.

48.11.5.3 Notifications
Accessories supporting AVRCP:

 ● Shall register for notifications.
 ● Shall not perform repetitive device status polling.

Every device in the role of an AVRCP Target supports registering for notifications, as described in
Section 6.7 of the Bluetooth Audio/Video Remote Control Profile Specification, Version 1.4. The
commands RegisterNotification and GetPlayStatus are supported for these notifications:

 ● EVENT_PLAYBACK_STATUS_CHANGED
 ● EVENT_TRACK_CHANGED

48.11.5.4 Play/Pause Button
Accessories supporting AVRCP implementing a Play/Pause control surface shall confirm the playback
status of the device using AVRCP Notifications (page 214), before sending a Play or Pause command.
See Supported Operations (page 214). Specifically:

 ● If a device notifies the accessory it is paused, pressing the accessory's Play/Pause control surface
should send a Play command.

 ● If a device notifies the accessory it is playing, pressing the accessory's Play/Pause control surface
should send a Pause command.

 ● The accessory should not infer device playback status based on the number of times the Play/Pause
control surface has been pressed.

48.11.5.5 Volume Handling
Accessories supporting AVRCP should support Absolute Volume, as described in Section 6.13 of the
Bluetooth Audio/Video Remote Control Profile Specification, Version 1.4.

Every device in the role of AVRCP Controller supports volume handling.

48.11.5.6 Browsing
Accessories supporting Browsing (in controller role) as part of AVRCP:

 ● Shall not try to index or cache the entire library upon connection. The device may contain tens of
thousands of media items, and each may be present multiple times in the hierarchy.

 ● Shall not fetch all items when browsing a folder; only fetch items displayed to the user. The accessory
may prefetch a few items to improve the responsiveness of the user interface.

 ● Shall not reorder items (for example, alphabetically).
 ● Shall not assume UIDs to be statically defined, especially in the root folder. The ordering and UIDs

of folders and items may change at any point in future releases.
 ● Shall send the SetBrowsedPlayer command after receiving an EVENT_UIDS_CHANGED

notification.
 ● Shall not assume the UID passed to the PlayItem command will result in the media player playing

the UID.

48.11 Profiles

Currently only the built-in Music app supports browsing. When switching between players, an
EVENT_AVAILABLE_PLAYERS_CHANGED notification, and an EVENT_ADDRESSED_PLAYER_CHANGED
notification will be generated. The UI needs to look at the feature bit mask of the listed player to
determine whether browsing is currently available.

All devices running iOS 6.0 or later support AVRCP Browsing.

48.11.5.7 iOS App-Provided Metadata
An audio app running on a device may use the iOS Media Player Framework to provide metadata about
the current audio stream to the accessory using AVRCP. Requirements and usage for these messages
may be found in the MPNowPlayingInfoCenter class in Apple Media Player Framework
documentation.

48.11.6 Advanced Audio Distribution Profile (A2DP)
See Advanced Audio Distribution Profile (A2DP) (page 198).

48.12 Audio Routing
Accessories can differentiate between various audio content provided by a device, and determine
playback behavior.

An accessory can receive audio data from the device using either of two Bluetooth profiles:
 ● HFP using eSCO channel.
 ● A2DP using ACL channel.

The device determines which channel to use, depending on how the audio content is used. An audio
path created for two-way communication (for example, phone calls or FaceTime) always uses the HFP
(eSCO) route for sending audio data. Music and similar content uses the A2DP channel route. In the
absence of a defined route, audio playback defaults to the device.

48.12.1 Audio Data Received using HFP Profile
Most of the audio content sent using HFP (eSCO) route requires two-way communication. Scenarios
where HFP (eSCO) is used include, but are not limited to: cellular calls, FaceTime, and voice mail.

The accessory speaker and microphone should be dedicated to the HFP (eSCO) route, and not
mixed/muxed with any other audio sources.

48. Bluetooth

48.12 Audio Routing

48.12.2 Audio Data Received using A2DP Profile
Audio content transferred using A2DP profiles can be broadly classified into two categories:

 ● Audio content from music, video, or game-like applications.
 ● System-generated sounds used for alerts and notifications.

48.12.2.1 Differentiating Audio Content from System Sounds
Music-like content can be differentiated from system sounds by adding support for Audio/Video Remote
Control Profile (AVRCP) version 1.3 or later. The AVRCP profile allows an accessory to be aware of the
audio playback device state, using notifications. See Audio/Video Remote Control Profile (AVRCP)
(page 214).

When a device initiates audio playback over an A2DP channel for playing music content, an AVRCP
notification EVENT_PLAYBACK_STATUS_CHANGED is sent to indicate playback status has changed
to the play state. See Section 6.7.2 of the Audio/Video Remote Control Profile Specification, Version
1.4. This indicates audio data using the A2DP profile contains music. When a device initiates audio
playback over an A2DP channel for playing system sounds, no AVRCP notifications are sent.

Figure 48-1 (page 217) and Figure 48-2 (page 218) show the difference between notifications for music
playback, and system sounds.

48.12.2.2 Expected Audio Routing Behavior for A2DP
The accessory should tune its audio routing behavior based on audio content over the A2DP channel.

If audio data contains music, accessory speakers are expected to be dedicated to audio data using the
Bluetooth link, and any other audio playback is paused. If audio data contains system sounds, it is
expected the accessory can render audio as desired. If the accessory is playing audio from a different
source, it is not necessary to pause existing audio playback on the device, and system sound data can
be mixed with the existing track for playback.

48.13 HID
When implementing HID over Bluetooth, the accessory:

 ● Should support Bluetooth HID Profile 1.1.
 ● Should support Sniff Mode for Low Power Consumption (page 207).
 ● Should use the following parameters in SDP for sniff subrating:

 ● HIDSSRHostMaxLatency - 450 ms (720 slots)
 ● HIDSSRHostMinTimeout - 45 ms (72 slots)

 ● Should use a typical report packet of 22 bytes or less. This is small enough to fit into a DH1 packet
with L2CAP and HID header.

48. Bluetooth

48.13 HID

The Bluetooth 4.0 specification introduces Bluetooth Low Energy (BLE), a wireless technology targeted
for accessories with limited battery resources. If Bluetooth Low Energy is supported, the accessory
should follow the guidelines in this section.

49.1 Role
The accessory should implement either the Peripheral role as defined in the Bluetooth 4.0 specification,
Volume 3, Part C, Section 2.2.2.3 or the Broadcaster role, as defined in Section 2.2.2.1.

49.2 Advertising Channels
The accessory should advertise on all three advertising channels (37, 38, and 39) at each advertising
event. See the Bluetooth 4.0 specification, Volume 6, Part B, Section 4.4.2.1.

49.3 Advertising PDU
The accessory should use one of the following advertising PDUs:

 ● ADV_IND
 ● ADV_NOCONN_IND
 ● ADV_SCAN_IND

ADV_DIRECT_IND should not be used. See the Bluetooth 4.0 specification, Volume 6, Part B, Section
2.3.1.

49.4 Advertising Data
The advertising data sent by the accessory should contain at least the following information as described
in the Bluetooth Core Specification Supplement, Part A:

 ● Flags
 ● TX Power Level

49. Bluetooth Low Energy (BLE)

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

219

 ● Local Name
 ● Services

The Local Name should match the accessory's markings and packaging and not contain a colon ':' or
semi-colon ';'.

The accessory may put the Local Name and the TX Power Level data in the SCAN_RSP PDU if, for
example, it needs to reduce power consumption or not all of the advertising data fit into the advertising
PDU. Depending on its state, the device may not always perform active scanning.

The primary services should always be advertised in the advertising PDU. Secondary services should
not be advertised. Services not significant to the primary use case of the accessory may be omitted if
space is limited in the Advertising PDU.

The advertising data and the scan response data in the SCAN_RSP PDU should comply with the
formatting guidelines in the Bluetooth 4.0 specification, Volume 3, Part C, Section 18: it starts with a
length field, followed by AD Type and AD Data.

49.5 Advertising Interval
The accessory should first use the recommended advertising interval of 20 ms for at least 30 seconds.

If it is not discovered within the initial 30 seconds, Apple recommends using one of the following longer
intervals to increase chances of discovery by the device:

 ● 152.5 ms
 ● 211.25 ms
 ● 318.75 ms
 ● 417.5 ms
 ● 546.25 ms
 ● 760 ms
 ● 852.5 ms
 ● 1022.5 ms
 ● 1285 ms

Note:
Longer advertising intervals usually result in longer discovery and connect times, but may
lower accessory power consumption.

220

49. Bluetooth Low Energy (BLE)

49.5 Advertising Interval

49.6 Connection Parameters
If both the Central and Peripheral support the Connection Parameters Request procedure, then either
shall use the procedure. The device will not read or use the parameters in the Peripheral Preferred
Connection Parameters characteristic. See the Bluetooth 5.3 Specification Volume 6, Part B, Section
5.1.1 Connection Update procedure for details.

Connection parameter requests may be rejected if they do not meet the guidelines in this section.

General connection parameter request guidelines:
 ● Peripheral Latency ≤ 30 connection intervals.
 ● Supervision Timeout from 6 seconds to 18 seconds.
 ● Interval Min ≥ 15 ms.
 ● Interval Min is a multiple of 15 ms.
 ● One of the following:

 ● Interval Max at least 15 ms greater than Interval Min.
 ● Interval Max and Interval Min are both 15 ms.

 ● Interval Max * (Peripheral Latency + 1) of 6 seconds or less.
 ● Supervision Timeout greater than Interval Max * (Peripheral Latency + 1) * 3.

If Bluetooth Low Energy HID is one of the connected services of an accessory, a connection interval
down to 11.25 ms may be accepted by some devices.

Note:
When Interval Max and Interval Min are both 15 ms, some devices (such as Apple Watch) will
offer a 30 ms interval to better balance power and performance constraints.

Apple Watch connection parameter request guidelines:
 ● Interval Min ≥ 30 ms.
 ● Interval Min is a multiple of 30 ms.
 ● One of the following:

 ● Interval Max at least 30 ms greater than Interval Min.
 ● Interval Max and Interval Min are both 30 ms.

49.7 Data Packet Length Extension
Data Packet Length Extension increases the maximum data length from 27 to 251. Using larger
per-packet data lengths improves radio efficiency, greatly increasing application data rates and boosting
battery life. See the Bluetooth 5.0 specification, Volume 6, Part B, Section 4.6.6 for details.

Accessories should support Data Packet Length Extension for best performance with devices.

iOS devices and Mac computers operating as the Central will negotiate optimal data packet lengths
based on various factors, such as connection event length, system topology, and protocol.

49.8 Privacy
The accessory should be able to resolve a Resolvable Private Address in all situations. Due to privacy
concerns, the device will use a Random Device Address as defined in the Bluetooth 4.0 specification,
Volume 3, Part C, Section 10.8.

49.9 Permissions
The accessory should not require special permissions, such as pairing, authentication, or encryption
to discover services and characteristics. It may require special permissions only for access to a
characteristic value or a descriptor value. See the Bluetooth 4.0 specification, Volume 3, Part G, Section
8.1, fifth paragraph.

49.10 Pairing
The accessory should not request pairing until an ATT request is rejected using the Insufficient
Authentication error code. See the Bluetooth 4.0 specification, Volume 3, Part F, Section 4 for details.

If, for security reasons, the accessory requires a bonded relationship with the Central, the Peripheral
should reject the ATT request using the Insufficient Authentication error code, as appropriate. As a
result, the device may proceed with the necessary security procedures.

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

222

49. Bluetooth Low Energy (BLE)

49.8 Privacy

Similarly, if the device acts as a Central and a GATT server, it may reject an ATT request using the
Insufficient Authentication error code. The accessory should initiate the security procedure for pairing
in response.

Pairing may require user authorization depending on device. Once an accessory is paired with a device,
the accessory shall retain the distributed keys of both central and peripheral for future use. If the pairing
is no longer required, the accessory shall delete both sets of keys.

49.11 MTU Size
An accessory supporting packet length extension shall perform the packet length update procedure
before performing the Exchange MTU Request handshake, see Data Packet Length Extension (page
221).

Devices will support and request an MTU size larger than the default during the Exchange MTU Request
handshake. See the Bluetooth 4.0 specification, Volume 3, Part F, Section 3.2.8.

When operating as ATT client, the device will request the optimal MTU size based on factors such as
the Bluetooth topology, connection event length, maximum data length, and protocol (GATT or
connection-oriented L2CAP).

An accessory operating as ATT server should select an MTU equal to or greater than the device's MTU
request.

49.12 Services

49.12.1 Generic Access Profile Service
The accessory should implement the Device Name characteristic per the Bluetooth 4.0 specification,
Volume 3, Part C, Section 12.1. The Device Name characteristic should be writeable.

49.12.2 Generic Attribute Profile Service
The accessory shall implement the Service Changed characteristic only if the accessory has the ability
to change its services during its lifetime.

The device may use the Service Changed characteristic to determine if it can rely on previously read
(cached) information from the device. See the Bluetooth 4.0 specification, Volume 3, Part G, Section
7.1.

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

223

49. Bluetooth Low Energy (BLE)

49.11 MTU Size

49.12.3 Device Information Service
The accessory shall implement the Device Information Service. The service UUID for this service should
not be advertised in the Advertising Data. The following characteristics should be supported:

 ● Manufacturer Name String (26 characters maximum).
 ● Model Number String (26 characters maximum).
 ● Firmware Revision String
 ● Software Revision String

49.12.4 Available Services
With iOS 7.0, any device makes Battery Service, Current Time Service and Apple Notification Center
Service (ANCS) available to an accessory. The Current Time Service supports the current time and
local time information characteristics. The service does not provide an "Adjust Reason" when the
current time changes. ANCS uses 7905F431-B5CE-4E99-A40F-4B1E122D00D0 as its UUID.

These services are not guaranteed to be available immediately after connection and the accessory
shall support Characteristic Value Indication of the Service Changed characteristic (see Bluetooth 4.0
specification, Volume 3, Part G, Section 7.1) to be notified when the services become available. The
device will maintain a connection to an accessory as long as it is paired and uses one of the available
services.

49.13 GATT Server
With iOS 6.0, applications may contribute services and characteristics to the GATT server the device
makes available to the accessory. The recommendations in this section apply to the accessory in this
case.

The following services are implemented internally by iOS and shall not be published by third-party iOS
applications:

 ● Generic Attribute Profile Service
 ● Generic Access Profile Service
 ● Bluetooth Low Energy HID Service
 ● Battery Service
 ● Current Time Service
 ● Apple Notification Center Service

The device implements the GAP Service Changed characteristic, because the database contents can
change at any time. The accessory should therefore support the Characteristic Value Indication of this
characteristic and, upon receiving indications, invalidate its database cache accordingly. See the
Bluetooth 4.0 specification, Volume 3, Part G, Section 7.1.

2023-10-10   |   Copyright © 2023 Apple Inc. All Rights Reserved.

224

49. Bluetooth Low Energy (BLE)

49.13 GATT Server

The accessory should minimize the use of ATT/GATT requests and commands and only send what is
necessary. For example, do not use GATT Discover All Services when the accessory is looking for
specific services. Use Discover Primary Service By Service UUID instead. Less airtime equals less
power consumption and better performance for both the accessory and the device.

When third-party iOS applications discover services on the accessory, the following services are used
internally by iOS and are filtered out from the list of discovered services:

 ● Generic Attribute Profile Service
 ● Generic Access Profile Service
 ● Bluetooth Low Energy HID Service
 ● Apple Notification Center Service

The accessory should be robust enough to handle any error gracefully. Pairing and Characteristic Value
reads/writes may fail if the application owning the service is not in the foreground and is not entitled
to run in the background.

If an ATT Prepare Write Request is used, all queued attributes are contained within the same GATT
Service.
