Bluetooth: Some devices not found - MTCB Android Head Units General

Hi,
my HU doesn't find some Bluetooth devices. The device I want to connect to is a Bluetooth 4.0 BLE device. My Android smartphone and my iPhone are able to find it. My OBD2 adapter is found.
Why is the list "filtered" like that? Is it possible to change it?
Head Unit: XTRONS PB78AA4RP
Tested Firmwares: Stock and Hal9k
Target Device: HM-10 with an Arduino (but others are missing, too)
Thank you for help!

Apparently with these units Android doesn't have direct access to the bluetooth module - it is handled by the MCU and therefore you can't use the standard bluetooth interface sorry!

Oh no, that's sad... Is there a workaround? E.g. is it possible to add a Bluetooth-Dongle via USB to get more results? Or is it possible to patch the MCU?
Thank you!

I have not seen a successful report of a USB bluetooth adapter working sorry, but I haven't tried

External Bluetooth

Hey. Is it possible to install an external bluetooth dongle to usb ports? The internal is defective and i want to use a2dp. I have deactivated the internal now in factory settings but if i connect a linux compatible bluetooth stick, nothing happens. I am new to android and i don´t know how to look for hardware devices in terminal and activate them. I saw a tread where wlan0 internal was replaced by wlan1 external, so maybe there is a option to do it with bluetooth.
Some one more knowledgeable then me might be able to help you.. But it sounds like it is a "module" problem..
As in you may need to have "modules" loaded in Android before it will recognize your new Bluetooth USB stick..
There is a manual work around as in using terminal commands that you could use if you have the modules for your stick.. It would be the same as what we had to do on for USB modems and USB wan sticks we plugged into the TF101 tablets..
Once you get it going you could as a rom developer to load them into the rom for you so you don't have to have a script and terminal to load them..
Hered a link to show what I am talking about..

Thanks, thats too much to handle it for me. I understand not much .
Unfortunately the MCU controls music output through Bluetooth so that's not possible. Even if your BT-Device was detected you would not be able to use ryou HU as "BT Headphones" for your phone. Android's Bluetooth stack does not support that.
Hello, my car (vw passat b7 variant) has a built-in bluetooth headset. Is it possible toconnectit somehow to the headunit or at least to have usable in paralel with the onefrom the headunit? I have a jooying android headunit and the bluetooth quality is awful and basically I cant use it.

Xtrons Android 6 Head unit.

Hi all
Just fitted an Xtrons Android 6 head unit into my Zafira, works well, but im wanting to add a native 4g/3g dongle that will detect Via USB so the unit has its own dedicated net connection.
Can anyone suggest any devices? The ones I have dont work and have some crappy CD Autorun feature which does not work.
Thanks in advance!

Block permanently the bluetooth MAC address

Hello.
How to block permanently the MAC address for one bluetooth device on rooted phone with TASKER?
You are looking to make sure your device never connects to that device?
Android will only pair with a device if it's been manually paired with to start with. Just don't pair that device and it can not connect to your phone.
Androidauto automatically connects to bluetooth after plugging the usb cable. I want to block the bluetooth connection to the car permanently (block MAC address)
I don't use Android Auto. A quick search on Google help pages seems to suggest the same thing. Go into Bluetooth settings and "forget" the car.
This solution not working (android auto automatically connect phone with car radio when plugged usb)
Well, yes, that's how Android Auto works. If the car or at least the radio is Android Auto, then when you plug in the USB, Android Auto launches and streams media and navigation through the USB.
However, the phone should go over Bluetooth, so if you remove the car/head unit from the phone's Bluetooth ("forget it"), then calls should go to a headset or some other Bluetooth device.
Are you trying to avoid having AA launch at all when plugged in?
You are rooted.. just disable Bluetooth completely. No Bluetooth for Android Auto and for everything :laugh: .. kmm how to do it in tasker is the real question
I disabled Bluetooth on my 2nd phone (connected to Android Auto, constantly connected, I just leave it in car) and my main phone is connected via Bluetooth (for calling,music,etc).
That's just one solution.
second solution is cloning mac adresses (both phones have same mac). But it doesn't work on all HURs (restrictions).
Good luck

Hi. I am also looking for a solution to the bluetooth problem.
In my case, I cannot disable the bluetooth services, since I need the bluetooth to connect with the ABD2 Adapter.
Is there any other solution?
I have looked for information on how to change to put the same bluetooth MAC on both phones but cannot find it.
Could you help me?
Thank you
Alexander

Go search in Android Auto section there you'll find multiple threads about 2 phones connections. Basically 2 phones have same MAC but in some HUR(radio media system) fails. So, there is no universal solution. It depends on your HUR.
Good luck.

Hi. I have searched several forums. In one of the threads, where the MAC change is discussed, they do not explain how to do it. Editing the EFS / Bluetooth / bt_addr file does not measure the mac address.
Changing the MAC is the only thing I couldn't prove yet.
You know how to change the mac I would be very grateful
Thank you

Omfg really?? ? https://forum.xda-developers.com/android-auto/android-auto-general/aa-phones-t3741671
Whats this link do? ? search is working I guess.
And you don't need to change MAC but you need to spoof it. Use (ed)xposed module to do so or you can try manualy ?.
Good luck.

Thank you very much, but for you to see that I use the search engine, the last one that wrote in that thread is me.
I tried exposed, but it was not trivial, since Edexposed and magisk gave me some problems. I tried some exposed modules but they failed. (of course I'm not the most expert).
I'm going to look for how to do it manually ...... I look for it with the term spoofing? some other search term?
Thanks for the patience and don't be mad !!!!

Android Auto / Apple Carplay via T Link app

Hey there
so i saw this app called T Link the other day being used by someone that claimed to bring wireless carplay to every Android Head Unit.
Does this app work? I tried it out myself and i keep gettings errors but no connection.
Does the app need Root Acces maybe?
Link to the app. The only thing I find is a screen mirroring app with bad reviews, specific to JVC headunits, which uses a USB connection, and has nothing to do with either Carplay or Android Auto.
First, if it provides Carplay capability to an AA headunit, it would run on an iPhone (IOS), not Android. Second, if a headunit doesn't support wireless AA, no app is going to allow a Carplay device to connect to it wirelessly, so "every Android Head Unit" - nope.
Seems you're missing something here.

Hi. I dont know about apple product but as far as an android user the T-link app provides for me wireless AA without fail.
Have not once experienced a dropout of connection loss or anything.
Only issue is what is an AA issue, and thats maps not being able to switch day/night mode by itself
Best regards
Using Tlink 1.7.7

The Tlink app is installed on ur android headunit. It connects your phone, either android or Ios to AA.
So he is actually spot on in his discovery
Best regards
Hey guys thanks for the help but I think the problem that I am having is a different one now.
So my headhunt does not support Apple CarPlay from the start.
I bought a adapter and tried to install the app that It comes with but nothing… no signal.
So the issue seams so be that there is not enough power coming out of the USB port.
When I use a splitter and plug the end for power into the lighter usb charger and the data one into the usb dongle it works no problem but it looks ****ty …
Any way or any adapter that I can get this fixed with?
Btw the head unit charges my phone without the adapter for about 3 seconds and then it Just shuts off

So, has nothing to do with Android Auto, where apps are not installed on the head unit. So, he's actually completely missed the mark for posting in the wrong forum.

Yes and no. Since you use the Tlink app to connect to AA. And that is installed on Head unit. Its not really a AA question, but related to that.
Since some need either Tlink or Zlink to connect to AA it might be more correct to move to a different thread than one thats about AA, but then again.
Im not a mod so not sure =)
But this is a different matter and not what was supposed to be the topic
Some with a bigger brain will surely help us out

I have seen someone talking about an adapter for this specific reason, but tbh you might wanna look in the headunit threads.
Tho if you google adapter for carplay there is quite a few hits, tho seems expensive.
Try and look in TS10 / Px6 head unit threads, there are some clever ppl there who is really helpfull
Best regards

CPC200 A2A - "Android Auto" Dongle? Similar to Motorola MA1?

Hi all!
I looked on the forums here and couldn't find anything about it... have you seen this carlinkit A2A adapter thing? Similar to Motorola MA1?
Seems like similar hardware as the Android headunits but on a dongle and then you connect it through USB and it streams via Android Auto. The usb seems to register that to the Android phones that it is a Android Auto device. the Android Auto UI apparently is stored and sent from the phone its self to the usb dongle and then sent to the android app. the app then sends touch and audio commands back to the usb dongle and then to the phone. I think it's interesting for folks like me with a traditional headunit with Android Auto/CarPlay to have full access to Android.
Does anyone knows about it? I guess we could have the same options as the headunits such as custom firmwares or maybe figuring out what software does that Android Auto integration and use it from an Android phone - getting full Android access...
A link of it from carlinkitofficial store:
CPC200 - A2A Wireless Android Auto Adapter for Car with Factory Wired Android Auto & Android Head Unit
CarlinKit A2A Wireless Android Auto Adapter Dongle, support original car built-in wired Android auto to wireless Android auto, allowing users to connect easily to car's existing Android Auto-capable infotainment system without having to plug any cables into your phone. Just connect via bluetooth...
