I want to use BC127 as audio source and as well as listen from remote device like walkie talkie. My configuration as follows,
I have enabled APTx LL for talkback feature using CODEC=6 ON command
PROFILES = 0 0 0 1 1 1 1 0 0 0 0 0
updated firmware to get cVc and APTx licence
connect remote bluetooth headset using open xxxxx A2DP command (LINK 10 CONNECTED A2DP xxxxx SUSPENDED APTX_LL SRC 0
LINK 11 CONNECTED AVRCP xxxxxx STOPPED)
music 10 play to stream audio
Issue is that I can only send audio from bc127 but on bc127 I could not hear anything from bluetooth headset. If I set sync profile for a2dp and pair to mobile device I can hear music. So hardware seem to ok for connection.
please help me out for configure bc 127 as audio talkback feature.
, and using license command I can see APTx and CVC license updated.
Talkback feature with my current configuration I found when stream audio it reboot remote device issue.
using hfp profile turn on, I can use talkback feature on mono channel. This required two bc127 modules.
out application needs one bc 127 and bluetooth headset with a2dp capable but talkback feature not working on bluetooth headset. For timebeing I will try hfp profile for audio walkie talkie feature application.
I found solution for talkback using AGHFP profile for bluetooth headset.
I just have to give command to dummy number like “call 12 incoming 123456” and on bluetooth headset push answer button. so “AGHFP xxxx IDLE WB” become “AGHFP xxxxx ACTIVE WB”.
