Subject: [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.
