Mayank,
if you run "hciconfig" with two adapters connected, you see both hci0
and hci1. you also see their bdaddrs.
iirc, when you create a bt socket we usually set "any" as the source
(remember setting local_addr with bacpy(&local_addr, BDADDR_ANY) in
a2recv.c). you can use a specific adapter and that is what you have to
do when you have two adapters and you want to go out on a specific one.
when you connect to a service, obviously you can specify the bdaddress
to connect to.
most of the core bluez code will allow you to set the src address using
command-line arguments (a good example is -i <hciX|bdaddr> in hidd) but
we've been lazy in the btsco code about that.
