I installed BlueZ and paired to a Nokia 6310i mobile a while ago. I didn't have any problem with the Bluetooth part of the setup - in fact the pairing was so easy I can't remember exactly what I did. I do remember putting the pin into the phone then into the little window put up by the pin helper - and it was done. My problems were all to do with PPP - which was another thread here.
Anyway I had it all working but needed to change to another, identical, Nokia (the original wasn't mine). Since then I've failed to pair the Z with the new phone despite trying every which way. I always get:
Can't connect RFCOMM socket: Connection refusedGoogling on this error I find that others have had this problem and there doesn't seem to be a common cause. Some seem never to have solved it. In my case I
know that this Z will attach to an identical phone.

Jul 5 17:17:17 pppd[1301]: Failed to open /dev/rfcomm0: Connection refusedThings I've tried:
- With and without a pin file. When I paired the first phone I got a window to put the pin in, but I've failed ever to get that window again. I think this is significant - I get the error message before I'm asked for my pin on the Z. /bin/bluepin is still the pin-helper and does work.
- PIN files with and without newlines. Some posts claim this is significant. I'm not sure it ever gets to read this though - see above.
- Deleting the old link-key file.
- With and without a rfcomm.conf file, and with a default one (bind no) and one set up for the new phone. (The hcid.conf and bt-uart.conf files are as installed.)
- Just about every hcitool and rfcomm command I can find
- Installed bluez-spd and checked that channel 1 is correct for DUN
- Deleting a lock file var/lock/subsys/bluetooth
- Uninstalling and reinstalling the bluez packages - trying to revert to the original situation.
- Checked that the Nokia firmware is the same on both phones. The new one is secondhand & BT works with a headset.
Not only can I not pair this new phone I now can't talk to the old one - I get the same error message now. The devices should still be paired (the Nokia thinks it is and I've put back the link-key file, though I might have damaged it since - I didn't take a backup of it before I started all this.)
I'm not sure that it's the
pairing process that's at fault - without a pin file I'm not even asked for my pin on the Z. Something to do with /dev/rfcomm0.
Any ideas?
Dave
