Hi,
I want to use BC127 in AGHFP mode, I have my bc127 EVM and bt headset device successfully paired, and I can send AT commands from headset to module. But when I apply analog audio at stereo mic input, nothing is heared in bt headset. I tried ROUTE command with several values but nothing found for my case. Could somebody help me?
Update: I can initiate the call by command ‘call 12 incoming 123’, the user will hear incoming call ring, than should press the button on headset and than can hear audio. How to remove this action from user?
I need send ‘call 12 outgoing 123’, then audio is on without user interaction. But also I need to handle button press by user (end or reinitiate call).
When we use wt32i module there was usefull ‘autocall’ feature. Can’t find similar in this module.
Hi @grip
Did you use a BC127 with a wire headset for the BT headset device? like below
BC127(conntected to wire headset)<— Bluetooth connection —> BC127(conntected to mic)
Is this bt headset apply for CALL case?
If not, can you clarify the bt headset you use?
Thanks.
It’s ok now. I use Nokia BH-216 ← bt connection → BC127 (audio line in connected).
Sending outgoing call command solves the problem. The reason of my confusion is because I previously used wt32i module from bluegiga that has ‘autocall’ feature (no need to send call command, voice connected automatically). BC127 has no this.
Hi @grip
You can check the FW you are using for BC127, if it’s not latest, please update the latest FW (https://source.sierrawireless.com/resources/airprime/software/bc127-firmware/#sthash.3UZ01pNb.dpbs) and then check again.
I tried your case on BC127 with the latest FW and BT headset. The call is activated after sending the command “CALL 12 OUTGOING 1” without performing any action. Here is my configuration and the steps:
