If not, you can still try a configuration like ulaw on air, ulaw > on HCI (no conversion in theory) no it is not a good idea. The chip will insert bits/bytes/frames as it thinks it needs to. The transparent audio is not guaranteed. Read the posts from the CSR guys for any details. > In this case, write a tool like scotest that always send FF.FF.FF...FF > frames (or anything you want) (write the same amount of data that you > receive). Then juste count zeros bits to detect BER, and 00.00.00...00 > frames for PER. Get a CSR development kit and get their BCCMD specification and use their internals to get the BER values.
