Connect RPI to Car Bluetooth
#1
I'm trying to get bluetooth connected from the rpi to my car so I can use the installed apps like spotify and kodi. If I go to the system desktop, I can find and pair to my car, but when trying to connect I get a prompt "Connection Failed - use audio menu to connect to this device"



The audio menu seems to disabled, the volume slider isn't active.

Have you seen and try this:

What is the result?
#3
The current version of pulseaudio-module-bluetooth was already installed, I made the edit to /etc/bluetooth/main.conf, restarted the pi. I couldn't figure out how to right click on a touchscreen, longpress/ two-finger didn't work so I ended up hooking up a mouse. Got the bluetooth to connect but when opening the pulse audio settings, there is no A2DP profile in the configuration tab.

Did you found solution? Could you let us know what have you tried ?
#5
I'm able to connect, but no audio plays.
Quote:1. Please install additional package needed for handling bluetooth via Pulse Audio
sudo apt-get install pulseaudio-module-bluetooth

The current version of pulseaudio-module-bluetooth was already installed

Quote:2. Edit /etc/bluetooth/main.conf file
MultiProfile = multiple

Made the edit

Quote:3. It would be good to restart the RPI

check

Quote:4. Pair your bluetooth audio device with Raspberry PI 3 and select it via right click on the tray's speaker
Bluetooth speakers paired and selected via right click on tray's speaker icon. Volume slider is active.

Quote:5. Open PulseAudio Voule Control tool (via Start menu) and select A2DP profile of your bluetooth audio device at Configuration Tab
there is no A2DP profile in the configuration tab.

The Pulse Audio is not part of the OpenAuto Pro and this configuration is related to Raspbian OS, so we are not experts here.

What we can suggest..

Are you using internal or external BT dongle? Did you try to switch between them?

Did you manage to configure RPI with your car before?

Are you able to check it with other car?



Regarding lack of tab in Pulse Audio you can check here:

Sorry for lack of detailed answer however we are not able to reproduce your issue.

So, I've managed to get some sound playing over the bluetooth speakers, albeit very choppy, using the kodi app. I still can not get openauto pro to play anything through the speakers. When I open pulseaudio while music is "playing" from android auto, I see the levels bouncing, but nothing is actually coming out of the speakers. I'm using the bluetooth from a raspberry pi 3b+

What about these:

Try to check with external BT dongle.
#9
I don't have an external bluetooth dongle, was hoping to use the built-in bluetooth in the raspberry pi b+.

I haven't configured bluetooth from the rpi to my car in the past.

I don't have a second car with bluetooth.

I don't know where you are based, but try this external bt module - https://www.amazon.com/Panda-Bluetooth-4...00BCU4TZE/

I'm using it in my system and can confirm it works for both A2DP and HFP. It's a non broadcom chipset. Only $12 so it's totally worth it.
