What is the BLE device (make, model, link)? As there is no standard for streaming audio with BLE, and no implementations that I know of, your request may prove difficult.

chayma, You still haven't answered what the make or model of the device is. Nobody can help you if they don't know what type of device it is (and exactly what type of device)

I have this information:
the audio transfer over the underlying BLE link with sufficient headroom for retransmissions during periods of RF interference, the audio, sampled at 16-bit 8 kHz, is compressed with ADPCM format resulting in a 4:1 compression ratio.
