Having trouble to try HFP Profile with BT Device

[EIC-SachinMehta]

Hello Team,

I have RPi 5 with Realtek USB dongle and I am trying to use example run_hfp_gateway.py to connect the HFP profile with my BT device and try to play a ringtone in my BT device but I am facing some issue while doing this.

I have disable the built in Bluez BT stack from the RPi and now only USB dongle is only BT adaptor shows while using hciconfig.

I am using below command
python run_hfp_gateway.py hfp_gateway.json usb:0 ringtone.wav

With above command, I am able to get the INCOMING_CALL indication on BT device side when I tried to run {"type":"incoming_call"} in other terminal but I am not able to hear the ringtone.wav content on other BT device.

Can someone please help here? I want to play a RING on my BT device using bumble + USB Dongle

We don't have full SCO support over USB right now.

Understood. Today I checked out your branch and try and I am still getting same failure. But yes, I didn't do pip install -e . So will do it and update here. Thanks.

Can you run with BUMBLE_LOGLEVEL=DEBUG and post the log? Did you add the +sco=0 suffix to your transport name (see earlier comment)?

My bad i didn't run with +sco=0 suffix but after running with it I am still getting failure. Here I have attached the logs with DEBUG LEVEL.

@barbibulle Have you able to resolve the HFP issue? Does your PR ready to merge to main branch?
