I have a SCR module on a arm platform,and have another
module on another arm. I can't create a rfcomm
connection!

and if I enter command "rfcomm listen 0 9" on one
platform,the result on another is
"Waiting for connection on channel 9
Connection from 4A:49:4E:00:15:2F to
/dev/bluetooth/rfcomm/0
Press CTRL-C for hangup".
And it didn't prompte to enter pin.
rfcomm0 {
# Automatically bind the device at startup
bind yes;
# Bluetooth address of the device
device 4A:49:4E:00:15:2F
# RFCOMM channel for the connection
channel 1;
# Description of the connection
comment "Example Bluetooth device";
}
I really have no idea what is wrong! And I can't read
these hcidump result,I am sorry!
Any help will be appreciated!

why don't you test these things with rctest. It implements the client
and the server side. The authentication (pairing) is only triggered when
you ask for it.
