Hello,
We use CC2564B in our product phone with BT stack2.1 of alpwise, when we use handset with MSBC mode and headset with CVSD mode, we find that during CVSD communication, if we disconnect CVSD equipment(power of equipment), when we use MSBC device after that, there will no voice. and after we do connect and disconnect of CVSD device several time, there will be no voice in CVSD devide too.
And another problem is that when we are using CVSD headset and switch to MSBC handset during call, and switch back, there will always have MaxSlotsChange event during using CVSD headset. But in our another produce with CSR chip, there is no such problem. And frequent switch over of two devices will cause HCI transport error.
The MSBC voice setting steps are the same as what described in CC256x Advanced Voice and Audio Features.
Do you have some idea how to solve this problem? Does CC2564B support this kind of swith or is there extral settings needed?
I used FD92 command to disable/enale MSBC codec, it seems better, but still has problem. Does CVSD has similiar command?
Thank you.
