Yes, it is possible to use full duplex A2DP as long as your devices support A2DP codec with full duplex. As for now, this project supports only FastStream codec which is capable of full duplex connection (aptx-LL is not supported yet). |

Hmm, I see, I need to figure out what my headphones support. Wasn't there a problem with the fact that when working through a2dp, the music is transmitted purely "aplay -D bluealsa:SRV=org.bluealsa,DEV=1C:91:9D:E0:0B:86,PROFILE=a2dp /tmp/f.wav ", but when working with HSP there is a lot of noise. example command "aplay -f S16_LE -D bluealsa:DEV=hci0,DEV=1C:91:9D:E0:0B:86,PROFILE=sco /tmp/f.wav" Moreover, there is noise both during recording and playback. |

Also, I still don’t quite understand how to work with HFP, I make a connection and receive a log: Then I want to play music but I freeze, maybe I need to run some other AT commands |

I assembled the bluez-alsa utility with debugging and noticed that there is a problem "bluealsa: 185.151596789: [645] E: ba-rfcomm.c:1540: AT handler IO error: Resource temporarily unavailable" this is when executing the script "hfp-ag-start 1C: 91:9D:E0:0B:86" from the thread https://github.com/Arkq/bluez-alsa/wiki/Using-BlueALSA-with-HFP-and-HSP-Devices |

Hello, I connect bluetooth headphones in HSP mode, I get a lot of noise during playback and recording, is it possible to use full duplex in a2dp mode on one hci device for playback and recording?
