    Hello Abdo,

    For bidirection links, you for now have 2 options:

    1) Classic Bluetooth: AGHFP and HFP: This will give you a 16kHz mSBC encoded stream. Latency is about 50ms.

    2) LE Audio: In this one, you can choose the sampling rate. However, this was only tested up to 32Khz. I don’t think 48k is supported by the standard,

    Can you file a ticket at https://www.iot747.com/support/open.php about this? This will allow it to be added to feature requests.

    Also, there is one option, the gaming mode. In this option, you get a 48k (out) and a 16k (in) connection. Search gaming in the UART command manual.
