Hi,
I've been working around trying to use two ore more
usb dongles at the same time ,(by the way I could send
files from one dongle at the same time to more than
one cellphones.)
as usual i start command line tool to witch i give the
address of one dongle
and in another konsole i start another programm using
the other dongle.
Both programs are used to send different files from
different dongles.
the way i bind the socket I use is this.
struct sockaddr_rc addr={0},laddr={0};
s = socket(AF_BLUETOOTH, SOCK_STREAM,
BTPROTO_RFCOMM);
addr.rc_family = AF_BLUETOOTH;
addr.rc_channel = port ; //remote port
str2ba( remote_addr, &addr.rc_bdaddr );
laddr.rc_family = AF_BLUETOOTH;
laddr.rc_channel=0; //local
str2ba( local_addr, &laddr.rc_bdaddr );
bind(s, (struct sockaddr*)sockaddr,
sizeof(laddr));
connect(s, (struct sockaddr *)&addr,
sizeof(addr));
......
recv();
send();
.....
close(s);
here remote_addr and local_addr are the string
representation of local and remote device addresses
given to the programm from the command line.
when one of the programs is working(sending and
recieving data)
i start the other one and after the first packet is
sent or the connection is made it all stops and both
the connections remains open.
I checked and i am the master in both cases.
Is this normal?
why i can't use them concurrently.
Best Regards
Ermal Mino.

in general this should work. However start using hcidump to debug this
and then send in more details.
