Modify scotest?
Now I have simply inserted a recording option in scotest ( like in hstest). It seems to work, I can transmit audio from Dongle to Dongle and record it,
but do I have to use the correct format (8Khz / 8 Bit Sample)?
Have you already done that - any experiences?

Hi Arnaud,

Using SCO for quality measurement is a good idea if your bluetouth device supports trasnparent audio, and if you configure them to use this mode. 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.
Regards
Marcel
