I think you are right.
My original purpose is to test the voice quality when 12 SCO server-client pairs
are running in the same room (which means 12 small piconets contending the
channel, although each pair has its own frequency hopping pattern).
Is there any good way to gather the voice quality information? (actually I don't
know how to tell a voice qualify is "acceptable" to human ears. is there any
good references?)
Thanks,
Jui-Hao

I have no idea. However you will see interference if the devices are
close. SCO consumes a fixed amount bandwidth.
