Xiaomi cant connect to bluetooth

[leifj79]

Have an xiaomi device and i cant connect to the rpi 2 zero by bluetooth using the latest code! Have tested BluemediaGER fork and there i can connect and it shows up correctly but then it cant connect to my cars android auto. The bluetooth doesn't show up unless i tell my phone to not show names on bluetooth and then i can see the mac adress of the device but pairing fails!

Try to build the project from source, with #7 have been made some changes in VID and PID of the USB mode that might help you with your problem

Im building from ca7859b and will be back with logs

You can also try the latest build on main from Github Actions.

Took the latest image 0.2 for Raspberry pi zero 2 w Took one dmesg to see what the state of things are and cat from var/log/mes...

Tested with one samsung older phone, but no bt device and same with my Xiaomi I have a german car, a passat from 2016

messages.txt dmesg.txt

The cable works atleast if i plug in the device in to a windows device a AAwireless device is recognized

The logs suggests that the headunit is not recognising and not sending the accessory start request. I'm out of ideas on why this would happen if Android Auto works in the car, as we're very close to what Pixel devices report via USB.

The head unit shows it's connected to Android Auto

I guess its my head unit that is to blame, i have to choose between android auto and mirrorlink and i think that is the issue :( haven't found any way to disable mirrorlink in the car, but newer models dosnt have mirrorlink and it seems fine!

It is technically supposed to work once you select Android Auto. I guess #2 also discusses about a headunit that has similar options for Android Auto and MirrorLink.

Yeah the BT starts and my phone tried to connect but doesn't connect before the head unit resets

Right, you can maybe try out the suggestion here: https://github.com/nisargjhaveri/AAWirelessDongle/issues/2#issuecomment-1783434263

Though, this looks like a common issue. Let me try to make a permenant change to fix the timeouts.

Tested BluemediaGER version and it works, now I'm going wireless with my Passat 🥳

Works with suggested solution

Had some new problems but I built from the tree optimistic_phone_connection and my wolksvagen accepts it without any issues! Awsome work!
