Speaker/Mic connected via Bluetooth USB dongle - cant record

[gsourav]

Hi All,

I have a Raspberry pi 2 mod B running Jessie. I have been trying like to build my own "Amazon Echo" like solution using a JBL GO bluetooth speaker (it has a built-in mic too) connected to the pi using a bluetooth USB dongle. So there is no wire from my pi to speaker/mic combo.

When I connect the speaker to my Ubuntu (16.04) laptop I am able to play & record audio with no problems (using arecord & aplay).

When I connect it with my pi, I am able to play using aplay command but unable to record using arecord. alsamixer shows the recording device when I connect the speaker/mic (please see attached screenshot).

My guess is that I am missing some bluetooth driver/config that will tell the system that the bluetooth dongle is connecting 2 (mic & speaker) devices as opposed to one. Not sure though.

I have spend weeks trying to search and resolve with no success and now I have decided to put in this forum in hopes to get help.

Many thanks for taking your time reading and helping me!

Warm regards,
Sourav Gupta

In order to play and record over Bluetooth, you would need to enable the HSP/HFP profile on the Pi. I've never seen that done. It would require at least building the latest PulseAudio, and possibly Ofono as well.

Hi Douglas,

Many thanks for your prompt response. I will probably give it a try and let this forum know about the outcome.

Thanks again.

Warm regards,

Hi there... was just wondering if you managed to get it working.

I'm planning to build something similar and wanted to see if i can rely on Bluetooth connectivity dor mic and sound.

Unfortunately, I have not been able to spend time on this project since then. So it still stays where it was back then. Sorry.

Best of luck for your project. I am sure there have been a lot of progress in this area since then so, if you happen to get it working please let me know. thanks!
