Hello,
Does Ubuntu, linux kernel 2.6.38.10, running bluez 4.91-0ubuntu1 have a
special security policy for incoming rfcomm connections on channel 1,
and not other channels?
I ask this because I can create rfcomm connections between two computers
on other channels (2, 3, 11, 13, etc.) but the listening computer
refuses connections when connection requests come in for channel 1.
I use the following commands:
on listening computer:
sudo rfcomm listen hci0 <channel>
on connecting computer:
sudo rfcomm connect hci0 <BD_ADDR> <channel>
When <channel> does not equal 1 both computers connect no with no
problem. When <channel> equals 1 I receive the error "Can't connect
RFCOMM socket: Connection refused"
I tried this in to two different environments. 1) in a X-session and 2)
in command line
1) in GUI on the listing computer a dialogue box pops up requesting a
pin for pairing. When I click cancel on the dialogue box of the
listening machine the error "Can't connect RFCOMM socket: Connection
refused" appears on the command line of the connecting machine.
2) in command line mode on the listening computer nothing appears and I
immediately receive the error "Can't connect RFCOMM socket: Connection
refused" on in the command line of the connecting machine
These problems do not arise when attempting to connect on any other
channels.
I have searched Google, looked at multiple forum posts on rfcomm
connections, looked at forum posts on peoples' problems with rfcomm
connections, reviewed this mailing list's archives, and I cannot find my
specific problem.
Thank you for any advice you can provide or resources to which you can
point me.
Regards,
Isaiah
