3. How to Control via External MCU
3.1.

How to Send AT Commands⚫ When BT is NOT connected, for ALL commands
1.

Output low to UART PD pin to enable UART interface. Please keep it LOW during thewhole time when sending AT commands.

2.

Send any AT commands you want. Please wait for at least 250 ms between sending
each command.
We recommend sending corresponding “Read” command (section 2.2.2) right after thedelay to know whether the writing is successful before moving on to step 3 to save yoursettings.
Please prolong the delay (over 250 ms) when writing or/and reading is not successful.

3.

Send command “ AT+RESET ” (not HW reset) to save all your settings.

4.

After sending “AT+RESET” command, do NOT write any command and wait at least 1
second for flash to update. Keep the power on during the whole period.

5.

Output high or NC to UART PD pin to turn off UART interface.

14⚫ When BT is connected for following commands ONLY
Write: AT+DISCONNECT, AT+SLEEP, AT+SETGPIOnnHIGH,
AT+SETGPIOnnLOW, AT+SETGPIOnnOFF
Read: AT?ADCVALUE
1.

Output low to UART PD pin to enable UART interface. Please keep it LOW during thewhole time when sending AT commands.

2.

Output low to flash default pin to enable receiving AT commands when BT is connected.
Please keep it LOW during the whole time when sending AT commands.

3.

Send “AT?ADCVALUE” or “AT+DISCONNECT” or “AT+SLEEP” or“AT+SETGPIOnnHIGH” or “AT+SETGPIOnnLOW” or “AT+SETGPIOnnOFF”.

4.

Output high or NC to UART PD pin to turn off UART interface.

5.

Output high or NC to flash default pin to disable the module to receive AT commands
when BT is connected.

3.2.

How to Transmit Data

* Only when BT is connected *1.

Output low to UART PD pin to enable UART interface. Please keep it LOW during thewhole time when transmitting data.

2.

Output high or NC to UART PD pin to turn off UART interface.

3.3.

How to Return to Setting of Default Flash* Only when BT is NOT connected ** Note that default baud rate is “9600bps,n,8,1”. For other default, pleasecheck “2.3 Default Info”

15

⚫ Use Hardware Method
1.

Read indicator pin first to check if BT is NOT in connection.

2.

Output a low pulse to flash default pin, then system will return to default setting.

3.

After outputting low pulse to flash default pin, do NOT write any command and wait atleast 1 second for flash to update. Keep the power on during the whole period.

⚫ Use Software Method1.

Output low to UART PD pin to enable UART interface. Please keep it LOW during thewhole time when sending AT commands.

2.

Send command “ AT+DEFAULT ”, then system will return to default setting.

3.

After sending “AT+DEFAULT” command, do NOT write any command and wait at least 1
second for flash to update. Keep the power on during the whole period.

RF Layout Suggestion (aka Keep-Out Area)

Make sure to keep the “No Ground Pad” as wider as you can regardless of the size of yourPCB.
No Ground Pad should be included in the corresponding position of the antenna in EACH
LAYER.
Place the module towards the edge of PCB to have better performance than placing it on thecenter.
Welcome to send us your layout in PDF for review at service@raytac.com or your contact at

End-Product Label

It is suggested using following content adding to package or user manual or label to obey theregulation. Any rules of end-product label shall refer to each certification for final reference.

11.10.1. FCC (USA)The FCC statement should be included in the user manual when there is no enough spaceon label. Otherwise, it should be included on the label.
“This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions. (1) This device may not cause harmful interference. (2) This device must accept
any interference received, including interference that may cause undesired operation.”
The final end product must be labeled in a visible area with the following: “Contain FCC ID:
SH6MDBT42Q”.

11.10.2. TELEC (Japan)
When manufacturer is placing the product on the Japanese market, the product must be
affixed with the following Specified Radio Equipment marking:57

11.10.3. NCC (Taiwan)
請依下列標籤式樣自製標籤，標貼或印鑄於器材本體明顯處，始得販賣或公開陳列。

Series標籤樣式

MDBT42Q Series

MDBT42Q-P Series

以 MDBT42Q 為例，平台廠商必須於平台上標示字樣「本產品內含射頻模組：ID 編號
CCAM16LP1180T2」。
「平台」定義如下：若器材組裝本案模組，消費者仍能正常使用該器材主要功能，該器材得視為平台。若器材不組裝本案模組，消費者不能正常使用該器材主要功能，該器材不能視為平台。該類不同廠牌型號器材組裝本案審驗模組後，須分別申請型式認證。

11.10.4. IC (Canada)

5812. Notes and Cautions
Module is not designed to last for a lifetime. Like general products, it is expected to be wornout after continuous usage through the years. To assure that product will perform better andlast longer, please make sure you:⚫

Follow the guidelines of this document while designing circuit/end-product. Any
discrepancy of core Bluetooth technology and technical specification of IC should referto definition of Bluetooth Organization and Nordic Semiconductor as final reference.

⚫

Do not supply voltage that is not within range of specification.

⚫

Eliminate static electricity at any cost when working with the module as it may cause
damage. It is highly recommended adding anti-ESD components to circuit design toprevent damage from real-life ESD events. Anti-ESD methods can be also applied inmechanical design.

⚫

Do not expose modules under direct sunlight for long duration. Modules should be kept
away from humid and salty air conditions, and any corrosive gasses or substances.
Store it within -40℃ to +125℃ before and after installation.

⚫

Avoid any physical shock, intense stress to the module or its surface.

⚫

Do not wash the module. No-Clean Paste is used in production. Washing it will oxidize
the metal shield and have chemistry reaction with No-Clean Paste. Functions of themodule are not guaranteed if it has been washed.

The module is not suitable for life support device or system and not allowed to be used in
destructive device or systems in any direct or indirect ways. The customer agrees toindemnify Raytac for any losses when applying modules in applications such as the ones
described above.
