If not, you can still try a configuration like ulaw on air, ulaw on HCI (no conversion in theory) 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. Enjoy !
