WT-32 Bluetooth module

Hi, I am a bit new with the bluetooth module. My main aim is to transmit the voice signal from the bluetooth module to the computer and then process the voice data simultaneously on matlab. I am more into DSP bit, so pardon me if I ask you any stupid questions re the bluetooth module. I am sure this might help some other newbies like me as well.

Until now, I have managed to get the bluetooth module working using FTD232 cable and 3.3 V converter. I am using tera term to program the bluetooth module. I have connected the microphone to the MICN and MICP pins along with a 3.3 V supply to the MIC-bias pin. I have configured the bluetooth module using SET CONTROL AUDIO INTERNAL.

Now, I would like to know how the bluetooth communication works in this module ? What i mean is that I would like to know some details about the packet structure that will be sent to the sink. Also, if you can recommend me some book or atricle related to bluetooth audio com., that will be reailly helpful.

Regards,

Vish
