Is LE Audio Controller backward compatible with the SoftDevice Controller?

[Kaizu]

Hello,

Is LE Audio Controller Subsystem for nRF53 backward compatible with the conventional SoftDevice Controller?

I'd like to add BLE-MIDI (MIDI over Bluetooth LE) functionality to the nRF5340 Audio application without modifying the precompiled LE Audio Controller. Is this possible?

Regards,

Kaizu

Hi,

It's not possible to modify the LE Audio Controller as we supply it as a pre-compiled hex file. But the LE Audio Controller can do regular BLE, so it would not be a problem. 

Best Regards,

Hello Priyanka,

Thank you for your reply. Can the LE Audio Controller do LLPM (Low Latency Packet Mode) connection? I'd like to minimize the latency of the BLE-MIDI connection.

Kind regards,

Kaizu

This might not be possible, because the LLPM is a feature we have on our SDC (SoftDevice Controller) and this will not be available on the LE Audio Controller since, I had mentioned earlier, it's not possible to modify the controller.
