Hi Markus ,

> 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? ;)

First of all you can have only one HV1 SCO link at a time. If you want
three, use HV3. This is because an HV1 packet carries only 10 bytes of
data. Thus in order to have a 64 Kbps HV1 link, SCO packets will have to
be sent every second slot (Tsco = 2) => there is no room for another SCO
link. 64 Kbps HV1 SCO link will cover 100% bluetooth bandwidth. Whereas
HV3 packet carries 30 bytes of data => you can maintain (theoretically
atleast) 3 SCO Links.

Best Regards,

Mayank
