Hi Marcel,

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? ;)

Regards,
/Markus
