Thanx for your response, I thought I had to set HV1 packets as I need to have 2 (hopefully even 3...) SCO connections simultaneously in a pico-net (this relates to the  conversation "Troubles with mulitple SCO connections" I posted yesterday) where it turned out that the USB dongle was the cause which is why I'm noe going directly for the embedded platform using serial hci connection...

But anyhow - to cut to the chase;
If I connect multiple SCO connections from my embedded platform, will the packet-types dynamically adjust when I add a second and even third SCO connection? This is why I though I had to specifically set packet-type to HV1... Could you (or someone that feel for it) just confirm my thoughts? ;)

Hi Markus,

  
I need to set SCO packet type to HV1 as well as I'd like to specify
that my device should be the "master" in a SCO connection. I known
that I can do this from the command-line using the hci* utilities, but
I'd like to set the packet-types to a known state when I initialize my
application (from code) and I'm sorry to say that I cannot find how to
go about and to that...

It has to be possible, but I've search through the hci_lib but without
success - yet ;)
Could someone point me in the right direction?
    

since hciconfig and hcitool can do it, you might wanna have a look at
their source code and see how they handle it.

However I can't advise you to play with the packet types at all. Leave
them as they are. The link manager of the Bluetooth chip knows best what
to do and what packet type to choose.

Regards

Marcel
