I have an Atoto a6 A6Y2721PRB. I'd like to use Bluetooth tether with my head unit, but I can't seem to get the internet connection to go through Bluetooth.

Is this possible with the unit or is the android version too old for this?
[Android Head-Units] Cartot:
Yea, I suspect that an app update caused that but I'm afraid it's a "core app" like maps or something. I haven't changed anything on the firmware, neither lately installed any newer apps so it must be an update. I'm trying to keep only the few necessary (for me) apps in the unit. I will try to update the firmware and see.

Bluetooth tethering is possible, yea. If I recall correctly though it's pretty slow, better off with data tethering over wi-fi.
[Android Head-Units] eriklanden:
I have connected my Samsung S10E to my new Atoto A6 A6Y2721PB via bluetooth.

When I play any audio from my Samsung it looses the connection and turns off media under my BT settings in the phone, then it auto-connect again. But every time I try to play any audio it looses the connection again.

I have tried with a Samsung S9 and it is the same problem also.

Both devices run Android 10. I got audio to work if a turn on development mode and change the settings from aptx to sbc, reconnect and start the stream from the phone. But every time I reconnect this setting is reseted.

Have some old Android devices I have not tested with yet, but I want this to work on my main phone that is the Galaxy S10E

Update I have tested with a Samsung S7 also now (Android 8) and it is the same problem, so I contacted Atoto that answered really quick and I have a suppurt issue going there now.

Update

I got an update file from Atoto that updated the Bluetooth firmware and now all working like it should again. Really goog support there!
[Android Head-Units] Lace'n'Pearls:
There is a particular Bluetooth on the Atoto that is the one that uses the data connection, I think #2 but I am not positive on that, so check the manual/support site/Amazon listing to be sure, so make sure you're connected to that one and have turned the Bluetooth Tethering on your phone on for it.

I hope updating the firmware works for you!
[Android Head-Units] Cartot:
Sadly the optimising thing is still there even after the update. Will also try format my sd card and copy again the files. The latest version is the AICE 9.6 right? From end of 2019.
[Android Head-Units] Lace'n'Pearls:
That's awesome! Nothing better than good customer support!

Try contacting Atoto support like this other guy did 'cause they fixed his problem, so maybe they will know what is causing yours.
[Android Head-Units] bmeek:
Interesting question. Your post made me investigate the DSP-408 to figure out what you're thinking... I've never seen a list of Bluetooth profiles handled by the A6 Pro, but I will say that as an Android tablet/head unit, it's generally too slow. The lag makes Google maps rather tedious to interact with, even more so when Pandora is running in the background.

What did you end up doing?
[Android Head-Units] yobyeknom:
I've got an Atoto A6 with my Galaxy Note 8 running Headunit Reloaded through USB and it works just fine. The only thing that bothers me is the Atoto A6 Headunit has this annoying ongoing call notification while in a call that blocks out the top 1/2 inch of my Android Auto on the screen. I reached out to Atoto and they told me there was no way to disable this. Anyone have any ideas how to get rid of this?
[Android Head-Units] jodybgoode:
Any pics of the s8 yet
[Android Head-Units] Lace'n'Pearls:
I wish I could say that I was spending time setting up my new A6, but of course my state had to close non-essential businesses the day of my app't to get it installed, so I'm still only dreaming about it. I'm trying to think about what apps to use on it, so let me know if you have any suggestions! I don't stream music or anything, but I play it from what is stored on my phone. I get 50 GB per month of tethered data, so have plenty for my needs.

Google Maps

Rocket Player (paid, beta tester) for music (I use it on my phone)

Xfinity Stream (there are times when I have to wait for hours in my car, so downloading from my DVR before I go would be helpful to pass the time)

Hulu (I don't really use it, but I get it free with my cell phone plan, so if I'm bored, hey)

I forget the name of the app that makes your home screen look amazing, but the one where you can see the music playing in the center circle

Any suggestions or comments on how you use your A6 Pro whether driving or parked?
[Android Head-Units] Fish.bait:
Did not do anything really.

If I want to listen to radio, I have an old 2din Pioneer headunit.

If I want to listen to music, I stream from mobile phone directly to dsp-408 over BT/aptX.

Only thing is, that with such configuration I have no steering wheel controls.
[Android Head-Units] Cartot:
Yea the support is great indeed. They fixed my issue, they told me that probably a newer Google App update was probably causing this and that was it, I just uninstalled Google App's updates and it's fixed. No idea if this will affect anything but not using the google app or assistant anyways. Would be great if we got a new firmware with a newer Android in future.
[Android Head-Units] yobyeknom:
I've contacted Atoto support and the exchange went something like this:

ME:

Is there a way to disable the phone call notification that drops down from the top of the screen while on a call? I'm using Android Auto on my phone with the app Head Unit Reloaded on the Atoto and the call notification is already at the bottom of the screen on Android Auto. The top of Android Auto is obscured because of this persistent drop-down notification while on a call.

Please advise.

ATOTO:

I am so sorry about that the Bluetooth phone call notification that drops down from the top of the screen can not be disabled,

this design is convenient for the users to answer Bluetooth calls on the car radio. Hope for your kind understanding.

Of course, I will forward your information to our engineers and try to do better in the future.

Please feel free to contact me if there is any question. I will always help you online.

Have a good day.

ME:

Thank you for your response. Do you have any recommended software to replace the dialer or the launcher? Could this stop the persistent ongoing call notifications over Android Auto?

ATOTO:

It is my pleasure to work with you online and thanks for your message.

I have just confirmed with our engineers that the Bluetooth phone call notification that drops down from the top of the screen can not be disabled,

I am really so sorry for the inconvenience to you.

I have forwarded your suggestion to our engineers and we will try to do better in the future, please trust us.

For now, if you do not like this item, may I have the order number of it firstly?

Then I will provide the return addrss to you if this order is still under warranty, please do not worry.

Are you OK with that?

ME:

I really don't think that I want to return it. For my use this is the only complaint. However, I would like to know if the the phone call notification appears when using the Android Auto dongle that Atoto sells? The ATOTO AC-CPAA48 - Is it any good? Are you still selling it. If yes, then I'll buy it if you can find it for me?

Is anyone else using Head Unit Reloaded and have this issue?
[Android Head-Units] Lace'n'Pearls:
Glad they were able to help! I plan on using the Google Assistant to make calls (on the rare occasions that I do, haha - like 6 minutes of calls and 4,000+ texts per month here ?), so I hope it doesn't happen to me 'cause I don't always use my car every two weeks, so it would restart often.

The new unit they're coming out with is going to be based on Android 8, but I don't know if they'll be upgrading our units to it (doubt it). I thought about waiting to install and get the new unit instead, but it looks like it is going to cost a lot more, so I can't afford to do that. I don't know if they're still working on the new units during this global crisis, so I don't know if they will be out in the eight weeks from when they announced it or not.
[Android Head-Units] bmeek:
great as a Head Unit, an android tablet not so much...

Well, I do expect you would be quite happy running the ATOTO A6 Pro's 4-channel line outputs to your DSP-408.

You'll be leveraging the head unit's decent support for steering wheel controls and its bluetooth with aptX to stream music from your phone with clarity. What are you using for an amp?

While I said that the A6 Pro lags as an "android tablet" for running numerous android apps, it does have a great screen and performs "head unit stuff" (bluetooth aptX audio & phone integration; fast (re)start-up, fast switch to reverse/backup cam; etc.) quite well.

Speaking of clean digital output from a head unit, saw that at least some of ATOTO's new S8 head units will include a "built-in DSP and support digital optical output (SPDIF Fabric output)". Funny, I don't see a lot of car amplifiers supporting optical audio input, but ATOTO's android head unit competitors are including it, so, I guess.
[Android Head-Units] diggitydog:
I have the same problem. When I first received it, it had worked fine. After the course of my full installation and adding some apps, it has stopped working. I haven't upgraded to the latest firmware yet. Anyone else have this issue?
[Android Head-Units] user9082390:
Anyone else having constant Wifi disconnects? Mine can connect for a minute or two, then it disconnects and says "Authentication failed". Obviously it authenticated fine at some point, as I am able to use the internet for a minute or two. The only way around this is to either reboot the unit or turn off wifi and turn it back on, and earn myself another couple of minutes of internet. I also noticed that each time it successfully connects to an access point, it has a totally different MAC address. It seems like it randomizes its MAC address every time it makes a new Wifi connection.

Atoto support is useless.

Thanks!

What for Settings use u with the Combination Android Auto + Headunit Reloaded + USB Cable?

Sometimes it works, sometime it said no connection. It ask me felt 20 times for authorization to use USB as Standard? Should i root it, when yes which App? Kingoroot?

Some Tipps would be awesome, that is at the moment my most Problem, Wheel Steering i got work, Radio is the Signal bad always, but i dont care when Spotify with AA work.

A6 Install in 2012 Toyota Sienna

Newbee here so pardon all my ignorance. Looking at options to update the factory radio on my 2012 Sienna XLE. ATOTO literature seems to have a specific model A6YTY721PR for Toyotas and Subarus but I can not find it available. Also not sure what other differences there are to the standard double DIN/ISO units.

Other info I am looking for includes trim kit and if I need a steeringwheel control interface box.

I asked ATOTO and got recommended the A6Y2721PR or A6Y2721PRB. Also the Metra 99-8229S Single/Double DIN Installation Dash Kit for 2011 Toyota Sienna (Amazon), and AX-TYAMP1-SWC AXXESS / RADIO INTERFACE 02-15 TOYOTA & LEXUS AMPLIFIED w/ SWC (ebay)

Any other options and recommendations. I've looked at other radios and installation videos and think I understand some of the issues.

Thanks is advance!

[Android Head-Units] bmeek:
don't mess with auto brightness

Yeah, at the moment I can't adjust the brightness at all. Glad it's on a reasonably bright setting as I start looking for ways to fix this.

I'm running ATOTO's "AICE OS 9.6" (from last November), and I believe the problem for me started here in a broken dialog box that I recall messing with: Settings > Display > Auto brightness > [select dialog]

[IMG="apparently broken dialog box"]https://xdaforums.com/attachment.php?attachmentid=4994313&d=1586884982[/IMG]

We see 3 choice buttons: "Close", "Headlight" and "Time". While "Close" could possibly be the result of a non-native English speaking engineer aiming at I-don't-know-what, it feels bug-related. I also notice that the dialog box lacks a "Close" button.

So I'm looking for a means to reset all brightness-related settings to the default, but I suspect I'll need to do a factory reset to get it back.

[Edit] I tried using Settings > Apps > Settings > Storage to delete all Settings' app data, but no luck. A factory data reset did solve the issue and restore my ability to adjust the brightness level!

FWIW, post-reset, the default value for "Auto brightness" is shown as "Headlight". My installation left that wire into the ATOTO disconnected (I always drive with my lights on), but I will not so much as open that buggy dialog box again.

[Android Head-Units] user9082390:
Hi Bad - Atoto does have Toyota specific models, but I don't believe they are to the same spec as the universal ones. If I were you, I would probably get the universal one and the correct trim kit. I got the Metra trip kit but different version for my Prius. And somehow the thing didn't need a steering wheel control box, but it did need the amplifier box (as my Prius has the JBL system with no nav). Retrospectively, I wish I had gotten the one with the steering wheel control box, as I did get some of my SWC to work, but not all, and others have gotten all to work via SWC box. So definitely drop the extra $40 for the SWC box if you can afford it, but the system will work without it. At least on my 2007 Prius it did.

If you are asking about Atoto in general, or head units in general, I recommend getting this Android head unit. The basic 2DIN head units you see at Best Buy or worse, are so proprietary. You can't do much thinking outside the box with them. Android head units have a large public support base, alot of people tinker with them and learn them. Atoto works for me because it was cheap, easy to order on Amazon, popular, and also had a terrific screen brightness (I got the one with no physical buttons, which sucks because I would prefer buttons, but it is brighter than the one with buttons). With all of these head units, brightness is a major issue. I have an Eonon in another car and it's 100% impossible to see during the daytime, even at the brightest setting, and my cars windows tinted. On both units I have a Carlinkit wireless carplay dongle, which miraculously, works (80-90% of the time). Between the Android head units and the Carlinkits, we have the same if not better performance and features than most other head units today, even factory ones. If you want to see the future, have a look at what is coming out of AliExpress for Android 9+ head units. They're really getting these things to be so full of features, but the manufacturer support will always be lacking.

Good luck, sorry I couldn't help more.
[Android Head-Units] badwabbit:
That was all helpful! Thanks.
[Android Head-Units] user9082390:
I too noticed an issue with brightness after upgrading the firmware. It turns out, it was due to two different brightness settings. I use the "headlight" option, so that when I turn on my headlights, the screen brightness changes. However, you must adjust the brightness twice. Adjust it once with headlights on, then turn them off and adjust it again. Then try flipping the headlights on again and see if the brightness dims when they come on. Somehow my non-headlight brightness got set to be the same as my headlight brightness, so it always seemed too dim during the day, until I realized you have to adjust it twice.

This may not be related to your issue but hopefully it helps some other lost soul like me out there.
[Android Head-Units] bmeek:
Thanks. That's interesting. As it happens, my installation, in an old Lexus ES300, doesn't have the orange dimmer/illumination wire (pin 11 on the ATOTO harness) connected. My car's Metra harness didn't have a corresponding wire and I didn't worry about it while installing since I pretty much always keep my headlights on while driving - day or night.

Perhaps the lack of a connection to pin #11on the A6 exacerbates or triggers the issue, but I fear that if you try to switch from "Headlight" to "Time" and back, or try to select "Close", you may duplicate what we saw.

[MENTION=10692143]diggitydog[/MENTION] and [MENTION=9092201]Cavrecon22[/MENTION] - is your dimmer/illumination wire to the A6 hooked up? Do you recall messing with the "Auto brightness" selection in settings before experiencing this frozen brightness bug?

In any case, what I experienced was that ANY attempt to adjust the brightness up or down had no effect. IMHO, if one can successfully enable automatic brightness, it should not preclude manual brightness adjustments. It seems I've had smartphones that have behaved in both ways, and the one that wouldn't let me adjust manually with auto turned on was frustrating (although at least the smartphone's auto brightness mode was based upon the actual measured ambient light - so it kind of worked anyway).

By the way, I sent an email to "support@myAtoto.com" alerting them to this discussion and asking if they have a patch. Perhaps they'll chime in :).
[Android Head-Units] tcbarney:
Can we revisit this? I'm having a similar issue and I'm wondering if I'm just missing something.

Why does standard Bluetooth connect automatically, but Bluetooth2 needs help?

Bluetooth 1 connects to my phone automatically when I power up the A6.

That triggers Tasker on my phone to turn off WiFi and turn on Bluetooth Tethering.

I further have the Blue Car Tethering app set to connect to Bluetooth 2.

But it never fully completes. I still have to force it from the Atoto side. Running Agama Car Launcher, I tap the Bluetooth icon, which brings up the Bluetooth 2 screen. Then I tap on my phone name, and I get a connection.

So I have it down to 2 taps, but I still don't understand why I have to force it from the Atoto side.

I tried the Bluetooth Tethering Manager app, running on both devices, but that doesn't work either, I guess because Atoto stops the service when it powers down and doesn't restart it automatically?
[Android Head-Units] Lace'n'Pearls:
I can't help with the Atoto side, but I wonder if you having Tasker try to do the tethering as well as Blue Car Tether is creating a problem?
[Android Head-Units] Cartot:
Speaking of the automatic brightness dim while turning the headlights on, it would be super cool if they could also turn the hard key backlight illumination on/off like this. Like when you turn on your headlights, the illumination of the keys to also turn on and turn off when you turn the headlights off, just like the rest of the car's interior lights! Hopefully they even implement this option cause it's very easy to happen and it would be super neat.
[Android Head-Units] Super_paulie:
can anyone actually get programs to run properly after a "ignition off" restart? the Atoto just kills all the background automation programs like KWGT and also Tasker, so all the widgets and things just dont work until you open the program and close it again, i assume to kick start the process. It works fine on a restart, its just the fast boot. I mean that is pretty poor. Has anyone been able to get tasker to fire up correctly, im pretty much maxxed out on what i can try.
[Android Head-Units] bmeek:
WiFi tethering > Bluetooth; A6 "fast boot" kills too many processes

Sorry. One of my current "1st-world problems" is the way the A6 Pro (ATOTO AICE OS 9.6) is currently too aggressive in killing processes on suspend+resume/"fast boot". I just wish it would not kill off whatever audio app I was listening to when I turned off the ignition, so that it would simply resume playing where I left off.

Why not tether with WiFi instead? I had spent some time playing with Bluetooth tethering to my phone but pretty quickly abandoned the effort because it was too messy (if not impossible) to automate, and what's more, the Bluetooth tether connection was too slow compared to Mobile Hotspot/ WiFi tethering. Without any automation on the A6 side (beyond using the screen unlock when Bluetooth1 connects to my phone), I now have my phone automatically fire up the WiFi Mobile hotspot whenever it sees a connection to the ATOTO Bluetooth device. In this scenario, the A6 cheerfully and automatically connects to my phone's WiFi hotspot shortly after it unlocks the screen due to my phone's Bluetooth connection. It all works automatically and consistently.
[Android Head-Units] bmeek:
WiFi tethering is working well for me...

Since WiFi tethering is working just fine for me, I wonder if you've got a reception/interference issue on the A6 side, or perhaps a performance issue on your phone's hotspot side... Assuming it's properly connected, where did you route your WiFi antenna that came with the A6? I had connected my WiFi antenna, left its cable coiled up but for about 15 inches, and routed the antenna end up high above the HVAC vents at the inside top of my center console. Have you tried reconnecting/moving your ATOTO WiFi antenna?

On the phone side, "Mobile WiFi hotspots" are inherently background processes that tend to lag when your smartphone gets busy or tries to sleep. How well does yours perform with other devices?
[Android Head-Units] user9082390:
My apologies - it happens with a standard home wifi / router as well as hotspotting. I don't hotspot very often, I just did so to verify that it was an Atoto problem not a problem with my home wifi.

And to the post above, yes I would also like to be able to get Torque to start automatically upon each boot (fast or otherwise), has anyone automated this?
[Android Head-Units] bmeek:
Ah... [MENTION=9521789]user9082390[/MENTION], I just recognized you from that Samsung-specific automate WiFi tethering thread that led me to Good Lock + Routines a few weeks ago. Sorry about my crossed-up-post assumption that you were trying to get Bluetooth tethering automated (rather than seeking a means to auto-relaunch apps such as Torque). Too bad we can't install Good Lock + Routines as a system app on the ATOTO.

Anyway, on your A6 WiFi issue, along with my talent for stating the obvious I'll assume you've pulled your head unit at least once to check the state of that external WiFi antenna (I have no idea if the A6 Pro has any functional "internal" WiFi antenna)... Warranty?
[Android Head-Units] Super_paulie:
I can confirm it does, with very limited range of maybe 30cm or so.

I have mine on the bench currently to try again in the relaunch issues and I don't have the antenna but can still connect. Also I use tasker on my phone to fire the hot spot when I get a Bluetooth connection, I'm with you on that one.
[Android Head-Units] tcbarney:
That's what I've ended up doing, and it works automatically and just fine. BT tether gave me fine throughput, though, and the battery usage was minuscule. With WiFi tether, I'll have to plug in more is all.
[Android Head-Units] bmeek:
Oh yeah - I had forgotten the battery angle (although that's what led me to investigate Bluetooth tether in the first place). I've since invested in a wireless charging car mount, and that sort of made the hotspot battery cost a non-issue.
[Android Head-Units] Super_paulie:
Same! Looks like we are all coming to the same conclusions here, think the we are maxed out on the units functionality. Not being able to access the whitelist for killed apps is a huge thing, spent days trying to find suitable work arounds as in a car you need the type of automation you can get from tasker and kwgt.
