Hi guys
I want to ask something, if someone knows about this:
How many devices can I connect at the same time? I need mouse, keyboard, printer and other device more. Could that be possible?
Thanks in advance

Don’t know exactly what are the limitations but you can have many of them connected at the same time.
On my phone I have a pair of connected hearing aids, a kind of pass through bluetooth device so the calling sound and media sound pass directly to my ears, a connected scale, a smart swatch and different BT earphones.
They all work when needed but can’t say if it’s real multitasking...
So I don’t think you should encounter troubles with your BT mouse, keyboard or such.
Then I don’t know if it’s a global problem with Samsung devices or only with rooted Samsung devices but you may loose connection after a while, from time to time. I solved the issue with a Magisk module as my Android devices are all rooted.
I haven’t had these problems in the past with older Samsung devices...
Good luck

[/B]Hi, just received my TD2 last week and is enjoying it. I have one major issue though. In my car I have a Pioneer AVIC X3 system including GPS, AV and BT. Its the one with the motorized monitor.
Unfortunately it seems that HTC has chosen a different type of BT that is NOT compatible with my Pioneer system.
Does anyone know of any fixes ?
Maybe you can draw more attention to your thread by adding an appropriate title. Good luck finding a solution!
I had a very high end pioneer, never again.
With mine, the problem was that the pioneer won't recognise PDAs, but it will recognise Smartphones and mobile phones. (Each bluetooth device broadcasts what type of device it is.)
I actually told pioneer the problem, how to fix it, and their support would only say "your phone is not on the supported device list". After i put the effort in to help them improve their systems dramatically, they couldn't even be bothered to acknowledge it / forward it to the development people.... so I spent £600 on a kenwood, worked like a charm, Kenwood's bluetooth modules are made by parrot. (also the £70 kenwood I also have works great too)
There are some registry edits that work to make your phone identify itself as a smartphone, as long as it has the MS bluetooth stack, not sure the exact details though, I've not needed to do that since I got rid of the pioneer.
Hi Trinode,
Thanks a lot for your comments. If I was to try the registry edit thing... would you know a link somewhere where I can get this information ? Otherwise I'm probably forced to change the Pioneer system also.
Hi Guys
Would really appreciate some help with this one, i am sure it been covered to some degree in other threads.
Since owning my unit I have wanted one application to run and I am not fussed about anything else, the app is ALPconnect.
ALPconnect is a application that connects to my radar detector via BT 4.0 only so it displays all the information on the dash for radar frequencies.
https://play.google.com/store/apps/details?id=com.alpriority.alpconnect&hl=en
Due to the limitations in the Bluetooth, no current rom has been able to allow the application to turn the BT on and search for the ALPconnnect Module
http://www.alpriority.com/product/alpconnect-bluetooth-module-gen2/
Over on the other forum i am apart of http://radarandlaserforum.com, one member has spent upwards of 2000$ buying android head-units to see if this app would run and connect on it.
our small thread is ongoing at @ http://radarandlaserforum.com/showt...-InCar-Enetertainment-unit-ALPconnect-Testing about this issue.
I don't normally ask for help, but I could really use some help and I am sure others on the forum that purchased it for that reason would greatly appreciate it too.
This is the last information I received from agentdr8, thank you aswell

It's severely limited, when compared to any other Android device with BT. This is due to the OEM's choice of the BC5/BC6 module, and their poor BT implementation. Instead of routing BT audio traffic through the Android system, like a normal device would, they route it through the MCU. That would be fine on its own, except they route pretty much all BT interactions through the MCU, via serial AT commands, which is very non-standard. Simple things like pairing, or using SPP profile just don't work, or require a bit of finagling.
On top of that, there's code (at least in MTCB; dunno about newer MTCD) in MTCManager that filters which devices can pair via BT for OBD use. It checks the device name and if it starts with OBD, it will allow it to pass to the next step during pairing. I can only imagine they chose to do that so they could sell their companion BT OBD adapters with the headunits?
My XMTC module had accounted for this limitation in name-based filtering (apparently not the only limitation though; if your adapter was at least v1.4 it should work), but it hasn't been updated to work on any 2016 roms. Since I no longer have time to maintain that project, it's been open sourced on my github. The BT pieces could be extracted into their own module, but I thought I had read someone else (maybe MVG70?) had made a BT xposed module for these devices to try and address compatibility issues.

Just as a thought
Would the MTCB be able to support external USB BT 4.0 thus removing the need for the messy internal BT

I think it's been discussed before, and no one has successfully added an external BT adapter to these headunits.
Has that group tried the app on the Parrot Asteroid? I know it wasn't the highest rated Android headunit, but it might be more "standard" than how these ones are configured.

Thanks agentdr8, but it does not really help the ones that splashed out and bought the HuFei units
Is the reasoning behind the external BT not working because nobody is interested in making it work or is it not technically possible?

Since the kernel is not open source, there's very little hope of adding the necessary drivers to support external BT adapters. Aside from that, I don't believe the BT stack that is included in these roms is standard.
I won't say it's impossible, as given enough time and money, anything is possible. But I doubt it's something anyone here can address without the sources.
Guess the manufacturer is reluctant to release the source then.

Just a couple of questions
1.Do you know if any developer is currently working injecting the drivers into the kernel, as impossible as it sounds.
2.If the manufactures were to fix this issue, what things should they include to make external BT work?
3.Have any of the manufactures hinted at releasing the source and letting other developers fix the issue with custom roms
Just on another note
I have 30 emails from Eonon saying that their tech cannot do this and have assured me that.
We have our own brand and R&D department.
We use our software.

Which I don't believe for a second
I'm quite interested in getting this fixed as well - I have both an ODB2 adapter and Navdy that I'm unable to connect due to this limitation. And the fact that there's no available workaround via External BT is infuriating.

From my understanding, the only way to get this to work is through an external (USB) BT adapter, since the built-in BT stack sends everything through the MCU instead of directly to android. So enabling the proper USB drivers for BT in the Kernel would fix it. I'm not aware of any other USB devices that don't work (maybe gamepads or other HID devices, unconfirmed) so it seems they've cherry picked which USB devices to allow. Considering the otherwise hackable nature of these devices, it'd make sense to me to just enable all available USB devices and let us plug in whatever we want to plug in.
I'm in the same boat. I have an OBD adapter (Hondash) which refuses to pair. I've tried 2 Xposed modules which are supposed to sort this. I'm wondering if my particular issue is down to my 5.1.1 ROM so might try it on my old RK3066 4.4.4 HU which I gave to my Dad.
So I'm monitoring this thread in the hope a fix is found.
I am doubtful, I have contacted Klyde/Eonon/others and nobody is willing to release the kernel source code or address the issue.
So when someone gets a copy from Klyde/some reseller/MTC or whoever and a developer has the motivation to correct it, that can be the only solution.
I have given up hope on this one

Does anyone know the location in the Android file system where the Bluetooth pairings are saved?
FINALLY! Someone with a similar issue. I've got a Valentine One, and the BT module for android, (connecting using YaV1) and I've been trying to get my android unit to pair with it as well. In for potential solutions.
This question may be off topic, and I apologize for that, but are you referring to the app not being able to turn on BT and look for the adapter; just getting stuck at "Turning on bluetooth..."?
I have an OBDII scanner which I can pair no problem. When I use a specific app (OBD Card Doctor Pro (or reg)) and attempt to connect it, I get a prompt letting me know that an app wants to turn on BT. I click allow and then it just sits there and never does anything. Is that the problem ALPconnect has?
Torque does not prompt me with this and initiates the BT connection just fine.
The main issue here is that the bluetooth hardware is in effect emulated to the android subsystem for the nice bluetooth dialler front end so android has no real control over the bluetooth hardwrae. These headunits have some real downfalls and this is one of them What we need is to break this open and rewrite it. Without sources we can't do that. We could maybe dissasemble bits and replace them in code but the rom is factory odd and hacked to bits!

So this emulated effect is what causes my system get stuck "Turnning on bluetooth..." if I understand you correctly? There's no Android control over the BT hardware so the request is just lot in limbo?
Hi guys,
I'm experiencing some odd issues getting bluetooth to work on my BMW Series 5, 2011. I've already used multiple devices over time, including most iPhones, Xiaomi, Pixel 2XL, etc, without any issues. My Note 9 is able to find my car's bluetooth device and apparently connects just fine, however, after requesting a couple of permissions it seems to struggle to maintain connection and then seems to keep frequently connecting/disconnecting.
I've already tried using a different "AVRCP Version" under Developer options, but it doesn't seem to make any difference. This is my first Samsung device, are there any frequent issues I may not be familiar with?
SM-N960F - Exynos
No root - up to date software
Cheers

Try to remove previously paired devices from your car, including this one and repair it.
You should leave the BT dev settings on their default as the phone is choosing the best based on the car's system.
Try also to go to Location's settings, improve location and disable always scanning of BT and Wifi.

Thank you, but unfortunately it didn't help. I even though it was due to being BT 5.0, but the Pixel 2 XL which I used before also had BT 5.0 and worked flawlessly. So weird
You might have to get a new car to go with the new phone

Don't be that person lol thats not helpful. I had these same issues when I owned the LG V20 and the only thing people did was mock my Bluetooth issues and told me to buy a new truck.

Lol... I'm sorry. If it makes you feel better I am having similar issues with my 2017 Audi A6. I have to constantly turn off my Bluetooth and turn it back on every time I get in my car to make it work.
I am having exactly the same issue with my 2011 330i. Connects then drops out. Phone says it is connected sometimes yet the signal strength icon on my car display flashes with no bars lit. I have unpaired and deleted the phone from the car but still will not work. I don't want to buy a new car either!!
So as far as I know the Sony Xperia XZ1 Compact is capable of Bluetooth 5.0, on other brands like Samsung with Bluetooth 5.0 you can connect 2 Bluetooth-devices at same time. As example you can listen on 2 bluetoothspeakers simultaneously. Is there any possibility to do that on Sonys Stock Software as well?
Thx in advance
Of I look on my cellphone (XPZ) there is in the Developer Option an option to change the count of BT DEVICES, but I didn't know if it's work or not
Well I tried this once before but now it worked. Now I can connect to both devices and switch audio between them and the device. So thank you:good:
Do you or anyone else know if it is possible to play audio on both aswell. In sound settings I only can switch like stated.

Meshing, connecting to multiple devices, is down to Bluetooth V5. But that doesn’t mean application developers are going to design audio streaming to multiple devices. This is pretty complicated and a bit niche, I mean why would you want to?
I wanted to share how to solve the problem of using bluetooth on a second phone having another mobile already connected to Android car.
The easiest solution would be to use a duplicate of the Sim card, but in my case my telephone company does not have that service and cannot be hired.
As you know, at the moment that a mobile phone connects to Android car, it no longer allows us to pair a second phone and use it to make calls via bluetooth, forcing us if we want to make calls to use the one that is connected by USB to Android car.
Well, using an application we can disable the sharing services by bluetooh and thus be able to use the 2nd phone. The negative part is that it is necessary that the mobile is broken.
The name of the application is: Service Disabler https://play.google.com/store/apps/details?id=com.kunkunsoft.rootservicedisabler&hl=en
“IT DOES NOT HAVE THE PHONE WITH ROOT”
To deactivate all the services of sharing via bluetooth is easy, we open the application and type the word bluetooth in the search area and it will already be in the list, and now it is just click on it and we will leave the option to deactivate everything.
From this moment on, all audio from the connected phone will be through USB.

This isn't really an Android Auto issue. But I understand a workaround may be useful if you have a headunit with this limitation.
How many phones can be connected depends on the headunit. My Kenwood will allow two phones to be connected and both can answer and make calls. Usually, I have my Pixel connected via AA, and my wife's iPhone will connect via Bluetooth at the same time. I can even select Bluetooth on the headunit and play music from the iPhone. In fact, although only two phones can be connected for calls, it will allow up to 5 phones to be connected at the same time for music (I've never tried that many, though).

Most cars have this problem. I think is very useful, i will implement it. It may be easiest solution. Phone has root to work mirroring so, probably with freeze bluetooth with titanium, could have the same, but havent try it yet..
