Is it possible to send the MEMS output (PDM stream ) over a Bluetooth ?(using BlueNRG-1 chip) to another Bluenrg-1 chip where I want to convert it to audio. (in simple I want to develop half-duplex communication using Bluenrg-1 chips)

Please reference STSW-BLUEMIC-1 software package, which demonstrates sending voice streaming over BLE.

The voice is originated from DPM stream of the digital MEMS microphone (MP34DT05-A or MP34DT04-C1) and BLE is SPBTLE-1S module (BlueNRG-1 based).
