I’m using a BC127 version 7.2 module. I would like to connect my phone android phone to this module. The profile I want is AVRCP and A2DP for streaming audio. When I try to connect these profiles using OPEN command after 2 or 3 seconds HFP profile gets connected automatically. Is there any way to avoid this?
Set the maximum number of HFP profiles to 0. Like so (the first number is the HFP parameter):
SET PROFILES=0 0 2 0 2 3 2 1 0 0 1 0
@tass2001 Thank you for replying. If I set the profiles like you said, I won’t be able to connect any HFP profiles. What I want is, I need to connect 2 devices, one with AVRCP and A2DP profiles and the other with HFP and A2DP profiles. So when I give the command “OPEN ‘mac_id’ AVRCP” , HFP profile is also getting connected. If I proceed with your way , I won’t be able to connect my second device because the HFP profile is disabled. This should not happen.
*Note- I want to connect 2 devices, 1. Only for audio(with HFP), 2. For phonebook access and calling facility.
Waiting for your reply…
I think the phone opens the HFP profile because it sees that the BC127 is available as an HFP sink. There is no way to prevent this, and as far as I know, the only way you’ll get past this is to have an MCU close the HFP link once connected (CLOSE ).
My current config is PROFILES=1 0 1 0 1 3 2 1 0 0 2 0. First I connected an HFP device but after 2 or 3 seconds A2DP and AVRCP profiles are getting connected. I used the CLOSE command to close the connected A2DP and AVRCP profiles. Next I want to connect a different device for media. So I connected the 2nd device using AVRCP and A2DP profiles. But after 2 seconds HFP profiles is getting connected. May be just like you said the phone saw the BC127 HFP sink. So I used the CLOSE command for closing the HFP profile of the 2nd device. It show the OK notification but the profile is not closed. I tried the CLOSE command many time but still no use. Any idea?
