Hello everybody

If i've connected multiple bluetooth dongles to my computer, is it possible
to seperate those two within bluez?
I mean controlling wich services run on wich dongle...

Another little question:
Does anybody know a bluetooth dongle that supports inquiry scan during
active connections?

kind regards
Marco

you can assign the services (application like pand) for each dongle, but
right now you can't make the sdpd differ between them.

Every CSR dongle with at least HCI 16.4 firmware.

I think we talk about the same thing, but just to get shure:
If i program two different rfcomm services, that would mean that i can 
control which service runs on which dongle?

Is the firmware updateable?
Do i have to contact the manufacturer?

if you use the RFCOMM socket then you simply bind() the socket to a
specific BD_ADDR of a local dongle.

Yes.

Yes.
