[Bluez-users] vhci and RFCOMM

[Papadopoulos Giannis]

Hi!

I am trying to create an RFCOMM connection between 2 virtual adapters in my
machine..

I' ve created the adapters and a connection between them...

Everything is OK, but I can't create an RFCOMM connection between them..

Terminal 1:
mordor:/home/dop # hcitool dev
Devices:
        hci0    7F:00:00:01:00:0A
        hci1    7F:00:00:01:00:0B
mordor:/home/dop # hcitool -i 7F:00:00:01:00:0A cc 7F:00:00:01:00:0B
mordor:/home/dop # rfcomm -i 7F:00:00:01:00:0A listen /dev/rfcomm0
Waiting for connection on channel 1
Can't open RFCOMM device: No such file or directory
mordor:/home/dop #

Terminal2:
dop@mordor:~> rfcomm -i 7F:00:00:01:00:0B connect /dev/rfcomm1 7F:00:00:01:00:0A
Can't open RFCOMM device: No such file or directory

What am I doing wrong??

first, don't use "hcitool cc ...". This command is never needed and it
is only there for testing purpose. Who said that you should use it?

Your problem is that you didn't created the RFCOMM device nodes.

you should create the rfcomm devices, you can creat them as follows.

#mknod /dev/rfcomm0 c 216 0
#mknod /dev/rfcomm1 c 216 0

(for further details read the man pages of mknod)

Regards,

Virat
