Hi everyone!

I own a Belkin F8T001 as a Bluetooth device (=>I installed the related firmware), but I get an error during the rfcomm connect command

here is my procedure (since only yesterdy I began playing with it, perhaps there is a previous error I make)

1) bluefw usb 001/00X
2) modprobe l2cap
3) modprobe rfcomm
4) mknod /dev/rfcomm0 c 216 0
5) hciconfig hci0 up
6) hciconfig
7) hcitool scan
8) l2ping 00:01:E3:06:FB:AF
9) added the following lines to /etc/bluetooth/rfcomm.conf:

rfcomm0 {
bind yes;
# Bluetooth address of the device
device 00:01:E3:06:FB:AF;
# RFCOMM channel for the connection
channel 0;
# Description of the connection
comment "S55";
}
10) rfcomm connect rfcomm0 00:01:E3:06:FB:AF

Everything has worked perfectly till now, but this last command returns "Can't connect RFCOMM socket: Resource temporarily unavailable" or "Can't connect RFCOMM socket: Function not implemented"

only during the latest command, I launched hcidump -X to get more info of what was going on (but I can't decode it's meaning alas):

Everything has worked perfectly till now, but this last command returns "Can't connect RFCOMM socket: Resource temporarily unavailable" or "Can't connect RFCOMM socket: Function not implemented"

how should RFCOMM channel 0 work? Use the one from the "sdptool browse" result instead.

Regards

Marcel
