My main mic is not working well, instead of chaging the module again I just got a bluetooth handsfree device.
But now i have the problem that even when the audio is fine. The telephone is not taking the bluetooth microphone source. I cant find any way to make the phone use the bluetooth device instead of the main mic.
I tested the handsfree with other phone and is working well.
As i understand HSP refers to headset and HFP to Hands free. so maybe HSP doesnt include the mic. and then could be that HFP 1.7 doesnt support HFP 1.5? It’s just speculation I really dont know about this protocols.
It’s not too detailed but from reading List of Bluetooth profiles - Wikipedia I think HSP should include the mic.
HFP is for cars (should also include mic).
True. will try to give a look further to see the compatibility of V4 and V5 and do the tests in safe mode. I’m afraid i will just find out that they arenot compatible and that’s all. will have to get a different handsfree
that looks great! is surely something i would consider. As others said, that module is the weakest part of the phone and sadly for a mechanical thing. it would clearly make more pleasant the FP experience.
