Thanks for this answer. But it won't work.
The IOMemoryDescriptor has a constant length of 816 bytes. SCO and eSCO
packets over HCI only allow a maximum of 255 bytes. And we get the same two
packets constantly. If we return an error, success, call the call back
routine with an error or a success - we get back the same packet all the
time. Even rewriting the code to be truly asynchronous (first return
SendSCOData(
) with success and then calling the SendSCOCompleted(
) with
success) there is not much change within the behaviour.
Well, perhaps anyone on the net finds our bug. The source is included and
public domain.
Are you using the PCM gate of the CSR chip? You seem to use a very special
CSR firmware which isn't available even to "normal" OEMs and consequently I
do not find any documentation on this CSR firmware you install with your
firmware updater.
