MTCB RK3188 bluetooth issues!! - MTCB Android Head Units Q&A

Hello everyone, I was wondering if this has happened to anyone else.
I updated my rom to "Johny DJ" MicroG apps 5.1.1, everything is working except bluetooth seems a bit strange, on the Bluetooth app I cannot see any connected devices, or I cannot search for any devices, but I can connect to it from my phone, if I make a call I can hear it though the car, but the app still does not see the phone, so I cannot search for any contacts.
Additionally it also means I cannot connect a OBD2 because I cannot see it through the unit.
The only Bluetooth that work is the WQ_BC5, can it be an issue with the bluetooth manager.apk and that specific module?
Had anyone else had this issue?
Thanks

[Q] Bluetooth GPS Receiver?

Hi All, I just had a question about bluetooth gps receivers.
I read awhile back that the Android OS's bluetooth stack was not equipped to handle serial port protocol connections over bluetooth which is what you need for a external bluetooth gps receiver. Just wondering if any of the new ROMs (2.1 or 2.2) have looked into implementing this? or if there's already an app out there.
i've looked and seems all the apps i found on market seem to be just data logging and doesn't allow you to replace the internal gps functionality.
this is a pretty good question. I have not seen anything about this mentioned on any rom. I would lean towards no but since i dont know for sure i figured i would help bump the thread hoping someone who knows for sure can shed some light
Seems to be working now -- my Samsung Galaxy S (running 2.1) can use my external Bluetooth GPS receiver now (not natively, but using a app called 'Bluetooth GPS Mouse')
okay, the app 'bluetooth gps mouse' doesn't seem to work. keeps saying i'm in china somewhere.
i actually found another program called 'Bluetooth gps provider' that works pretty good, except for google nav...
I informed them about the bug and today they released an update, so Bluetooth GPS Mouse should work now as well

LG G3 bluetooth problem with older car

Hi,
I tried connecting my bluetooth with my car (2003, bmw e46), the pairing works, but it keeps disconnecting and I can't receive any calls thru my car.
From what I've read, there is an issue with the bluetooth stack that was changed in android 4.2? Can I patch/edit it somehow so it can work?
Found a similar guide here (for the same car), but didn't manage to make the edits.

Finally managed to apply the fix in the url above and works perfectly.

Mi6 bluetooth problems

Each time I use Mi6 via bluetooth in car to answer/make calls - first call goes OK, and all others not - people I talk to don't hear me. It happena in 4 different cars so it's not car's problem. Mi5 was OK. I run 7.1.1 NMF26X global beta. miui 8 7.6.8 global beta. And can't solve it myself. Tried deleting and re-adding cars, restarted phone - nothing helped. When I switch to phone during call - it's OK. As soon as I switch back to car - same problem. No one hears me and I hear everyone.
Any1?
I'm sorry but I can't test because I don't have any Bluetooth devices.
Not using any bluetooth device either.

Ok, one by one.
1. My phone does not see andriod wear app on my smart clock with bluetooth --> My watch works, did you unpair your watch with old phone first? Android wear watch can only connect to 1 phone.
2. There's personal hotspot, you can see it in the settings menu.
3. GPS needs time to find your phone, you need to have wifi (or mobile data connection to assist the phone), if it located your phone, next time GPS will work faster.
It is a different issue with me: when paired with a BT device with the "phone audio" profile enabled, despite picking up the call on via pressing the green button on the touchscreen, it still defaults to the BT device (and I have to switch audio back to "phone" before the other person cuts off after hearing nothing). This is on the global ROM 8.2.2.0...
The global ROM seems buggy as hell...

Hello Friend.
The same happens to me.
It connects to bluetooth but I have no output or audio input.
Did you get it fixed?
Thank you
Everyone.
This is not xiaomi's problem.
This problem is due to oreo's new bluetooth stack.
There is no current solution to this. I've searched far, wide and deep.
Android has a great track record in keeping the bluetooth stack broken.
If you try to search google, you will find out that not only xiaomi phones have this problem.
The only theoretical solution is to port old bluetooth blobs, and somehow make it work. But as far as i know, no one has done this before.
There is hope that android pie will fix this. But from what i read, early builds of pie still has this problem.

chinese android head unit problem Play Store and Bluetooth

hello everyone,
I just installed a SEICANE chinese android head unit in my Fiat Ducato from 2017.
I connected the ISO port directly to the 2 connectors from the car, I've first tried to use a power harness including the CanBus decoder, but then the HU is dead. Without harness , the HU works (I guess the car already has a CanBus built in?).
The radio works very well. Also Wifi works well, I can surf on the Internet. But some apps I can not download (using Play Store). For example when I try to download TomTom GO, the HU tells me that there is no Wifi (although there actually IS Wifi!). Other apps are no problem to download (I've "fixed" this problem by installing Sygic i.o. TomTom).
I paired my Samsung XCover3 via Bluetooth and also problems: when I try to make a phone call, sometimes it goes to handsfree (like it should), but sometimes it does not (although the phone display opens on the HU). I did the pairing 10 times , but no difference. I also tried to make an Internet connection using Hotspot or tethering, but that also does not work.
I resetted the HU, but no improvement.
Does somebody knows these problems (and has sollutions to it)?
Regards,
Peter

Why Bluetooth connection is a mess on Pixel 3XL since 2020?

Hello
I'm facing the problem that the bluetooth connection to my cars multimedia unit is a big mess since 2020.
But not only when connecting to the cars BT. Every BT connection will randomly asks for permission to the contacts or messages...
The phone will not store this information correctly anymore. My car is an 2020 Opel and sometimes it says that the bt connection can't be established, but it actually plays music over this connection and phonebook is also transfered.
I have the pixel 3XL since it came out and it is completely stock non rooted or something like that (I'm to old for this stuff as a daily driver )
So, did google mess the driver up that it will not work correctly anymore? Or does someone know what's going on in the device?

Have tried different ROM's on this Pixel 3 XL so I completely understand the Bluetooth issue. Have grown to rely on turning off Bluetooth before using the passcode; kind of helps with the new ViPER4Android FX,
Since using ScorpionROM, haven't had any Bluetooth issues. Maybe give it a shot and see if it helps
