For what it's worth;

After having cross-compiled to my embedded system and leaving the

USB-dongle solution behind, everything now works like a breeze and I now
have a BT device hosting running 2 SCO connections and 3 RF_COMM sockets
simultaneously.
	
And what packet types are these two SCO connectionis using now?

Hi Brad,

Ok -- that does make my life a bit easier ;)

The target-platform for my app is indeed an embedded one with a serial interface to a BT module, so that's fine... However I'm developing the app on a "real" computer using an USB dongle, but I'll try to cross-compile and go for the intended target-platform instead and keep my fingers crossed...

Thanks all for your input!

It does work now on systems that use a serial hci connection (mostly
embedded) but that may not help you.

My spontaneous reaction would be; really?

My code is based on the socket-abstraction in BlueZ and it works fine for multiple ACL connections, and the SCO-option is only a second socket-invocation on top of that...? Confusing... There has to be some way to solve this? Setting SCO packet type to HV1 allows for three simultaneous SCO connections AFAIK - so this should not be limited in BlueZ - and if it really is, then why and how do I work around that.... I mean, RF_COMM / ACL sockets work just fine...

Regards,
Markus Adolfsson

What you are seeing is normal. The current code only supports one

It would be better if the existing code simply would fail to open a second
connection to avoid a lot of confusion.
