 Posted: Fri Jun 15, 2012 1:46 pm Post subject: Bluetooth phone modem + Networkmanager ? [solved with Hack] |
 |
|
I have a Nokia 5230 phone that I'm trying to use with bluetooth.
What does work: I can use the 5230 through /dev/ttyACM0 (USB Modem) to get a GSM link - so I suspect my ppp drivers and NetworkManager + nm-applet is working for that
What also works: After using blueman to associate and attach dial-up-networking to the phone, /dev/rfcomm0 shows up. I can minicom /dev/rfcomm0 (as root only; as a user it doesn't let me override the lock on the device probably because networkmanager is trying to use the device???) and issue AT commands to the phone which appear to work fine.
What doesn't work: nm-applet/NetworkManager never shows the phone as a possible connection system like it does for /dev/ttyACM0. I would think /dev/rfcomm0 and /dev/ttyACM0 would be very similar but different drivers - one is through USB, other is through bluetooth.
I recall this working in the past, but I don't recall if this was under Ubuntu that it worked...
Any ideas why my phone isn't showing up in nm-applet?

Your post has been languishing unanswered for a while so I'll have a go but I don't have direct experience of this ...
Have you enabled the modemmanager USE flag in networkmanager?
Cheers

Unfortunately I think it is set; that's the weird part: USB works just fine, just not bluetooth...
Also unusual: networkmanager-0.8.4.0-r2 has these USE flags set (and modemmanager is not a USE flag)
-avahi +bluetooth +connection-sharing -dhclient +dhcpcd -doc -gnutls -nss +ppp -resolvconf
Modemmanager is indeed installed somewhere in the dependencies list...

Ahh, NM is under pretty heavy development. Can you update to the latest available in Portage (0.9.4.0-r2)? That one does have the modemmanager USE flag. I am running ~amd64.

Update: I updated to networkmanager-0.9.4.0-r6 due to it becoming stable. It still does not detect the bluetooth device.
I found
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/583728
https://bbs.archlinux.org/viewtopic.php?id=147880
And seems that multiple linux are plagued by the same issue... Maybe even RH/Fedora?
Ahh some debug...

Hmm...what?
I didn't like the patch to remove just the ! so I completely removed the Bluetooth "no associated bluetooth device" section as suggested in the Archlinux post.
I tried removing my phone from bluetooth-manager and re-added it. It hung(!) when I tried to click on "allow dialup access".
IT WORKS!!!
Networkmanager sees my bluetooth modem and I can select it... and it dials out just fine!
As soon as I KILL the broken window, it kills the connection and I have to reboot, delete phone, and reinitiate the pairing again.
Ugh... a lot of the stuff should be there and working, just a few details here and there not setup right. Anyone else seeing these issues?
So I tried Blueman and it seems to work!
SO... I find a neat feature of portage: since networkmanager-0.9.4.0-r6.ebuild supports epatch_user, I think all that's needed is to make a file:
/etc/portage/patches/net-misc/networkmanager/bluetoothhack.patch (note there's tabs in this so if you cut and paste it won't work, pm me for the file with correct whitespace)
| Code: | --- src/nm-manager.c.orig 2012-08-30 08:32:27.845005846 -0600

return;
}
+*/
/* Make the new modem device */
device = nm_device_modem_new (modem, driver);

and then re-emerge ... voila! IT WORKED!
HACK summary to get Bluetooth to work in Gnome+NetworkManager:
1. Use net-wireless/blueman not gnome-bluetooth-manager
2. Create the above patch file in the directory stated above
3. emerge -1 networkmanager (the patch is for 0.9.4.0)
4. Restart networkmanager
And YAY! Bluetooth modem works once more!
