Damn, it means that if I want a service (UUID, RFCOMM channel)
to be available concurrently to several remote devices from a unique
computer, I need to have as many BlueTooth adaptors as possible
concurrent remote devices, and a service declared on the SDP for
each one ? and basically each Service server is a loop on listen / accept /
process /close without any fork, am I right ?

Ok, according to the former principle I suppose i.e. one service <=> one
concurrent connection to that service for an adaptor.
I have a binding question here : I've made simple tests, doing simple socket
applications (connect / send / close) from a computer to a another one,
and if for example I have declared a service on the second computer (let's
say on channel 14), when the client application is bound it's on local
channel
14 too (after a getsockname client-side), i've understood it's because of
the DLC
which is unique on both side of RFCOMM. Now let's assume I open another
application concurrently client-side, connecting to another remote device
but on channel 14 too, it will be smooth ? (I ask this question because you
say
"The reason is that for every outgoing connection a new local channel will
be
allocated which is independend from he remote server channel you connect
to")
and experience has showed something different. I will try more !!
Basically, it would be a computer trying to push data on as many remote
devices
as possible on the same remote channel, and I would like to use the max
connections
possible for each bluetooth adaptor !
Thanks **a lot** for your help !!
Oli
