[Bluez-users] RFCOMM error

[Bluez-users] RFCOMM error

Hi:

I have a an RFCOMM server process listening on one box.  From a Linux
laptop,
I just wrote a simple RFCOMM client to connect to it.  Very simple, via
AF_BLUETOOTH, SOCK_SEQPACKET and
BTPROTO_RFCOMM.

I got back errno as Bad File Descriptor.  When I strace it, I saw this line:

   socket(PF_BLUETOOTH, SOCK_SEQPACKET, 3) = -1  ESOCKTNOSUPPORT (Socket
type not supported).

What does that mean?  Did I construct the socket wrong?

thanks

Mark

for RFCOMM it must be SOCK_STREAM.
