We have a design including a CYW43455.  I was wondering if there was a way to configure the device to do a PCM loopback.  The 43455 would provide the CLK and SYNC signals, and echoes samples received on the PCM_IN pin out the PCM_OUT pin, without using the radio.

Thanks for the help.

That command worked great, thanks!

What document are the Vendor specific Bluetooth commands for the CYW43455 documented in?
