[Bug 416056] Re: Cannot open /dev/rfcomm0: No such device

[tony]

I had similar problems. A configuration that had worked find in 9.04 and
8.10 for using my Nokia N95 for dial up Internet access failed miserably
after upgrading to 9.10. To fix it, I had to make 4 changes. Looks like
the Bluetooth stack has changed...

1.  I had to add a semi-colon to the end of the device line in
/etc/bluetooth/rfcomm.conf as the lack of one was now deemed a syntax
error.

2. After running sdptool I found that the rfcomm channel number for dial
up access had mysteriously changed from channel 2 to channel 1.

3. The /dev/rfcomm0 entry is no longer automatically added at boot time.
I added

rfcomm bind yes

to /etc/rc.local to work round this and force rfcomm bind at boot time.

4. /usr/sbin/pppd needed to have the suid bit set i.e.

sudo chmod +s /usr/sbin/pppd

Then all worked fine
