I'm currently trying to create a Bluetooth headset and would appreciate some assistance sourcing a Bluetooth module. I need this module to be able to handle phone calls, music, and "normal" data transfer (preferably be able to send data while streaming phone calls).
I am looking at the CC2560B ( http://www.ti.com/product/CC2560/technicaldocuments )to fulfill my needs. I know it can handle music and normal data, but can it handle the 2 way communication of a phone call? I imagine the call will be sent with A2DP, which is a one way protocol so I'm really not certain.
Am I correct in thinking that if assisted A2DP and assisted HFP are enabled on the CC2506B that the data can actually flow directly from the Bluetooth module to the audio codec? This would be great if it is true. If the data completely avoids the controlling unit, is there a way to determine if a call (or music) is going on(without separate electronics)?
Lastly, what is required for me to correctly control the Bluetooth Module? I know software comes with the module, but I don't know what that software is. Do I need to maintain the Bluetooth stack? Is it as simple as sendBluetooth(data); ?
Any assistance would be great, thank you.
