Re: 1199:6832 Sierra Wireless, Inc. MC8780 not working with NetworkManager 0.8.3.998 / ModemManager 0.4
1) Does the device boot up in CFUN=1 mode already? This could be determined via minicom/screen without MM running. If it does (my 8775 modules do) then we could avoid this issue by having the startup code check AT+CFUN? before doing AT+CFUN=1 explicitly. I will try to implement this, in some way so that plugins can enable/disable this behaviour (Wavecom plugin will also use it) Cheers! -- Aleksander ___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

I now copied these two files in place and rebooted. As you will see in mm-ok.log, I got a working connection. I suggested to Aleksander on IRC to do two things... 1) Does the device boot up in CFUN=1 mode already? This could be determined via minicom/screen without MM running. If it does (my 8775 modules do) then we could avoid this issue by having the startup code check AT+CFUN? before doing AT+CFUN=1 explicitly. 2) Sierra documentation implies that their CFUN variant takes an additional optional reset parameter. Can you try (again using minicom/screen or whatever) the following? AT+CFUN=1,0 AT+CFUN=1,1 and look for which one does *not* cause the reset, and we could use that one for Sierra. But in the end I think (1) is the better choice. Dan ___ networkmanager-list mailing list networkmanager-list@gnome.org http://mail.gnome.org/mailman/listinfo/networkmanager-list

Hi, I 'm not a NetworkManager dev, just a fellow ubuntu user :)
From a cursory reading of the bug reports you cited it seems like some
sierra modems crash when ModemManager sends CFUN=1 to them.
Can you help verify if this is indeed the case with yours as well?
I put a version of natty's modemmanager with the attached patch
applied in my ppa. So, the only thing you need to do to test is:
sudo add-apt-repository ppa:pktoss/ppa
sudo apt-get update
sudo apt-get install modemmanager
restart networkmanager/modemmanager or to be 100% sure you
can just reboot.
Test to see if your device works now
sudo add-apt-repository -r ppa:pktoss/ppa
sudo apt-get update
(The last 2 steps are in order to remove my ppa to avoid it breaking
your system with my other experimental stuff).
Alternatively you can just build modemmanager with the attached
patch applied by yourself.
If the patched modemmanager works, then please say it so that
the appropriate quirk for your device can be added.
Thanks,
Pantelis

Hi, sorry to bother you with a user problem. I have a ID 1199:6832 Sierra Wireless, Inc. MC8780 Device. Unfortunately NetworkManager in Ubuntu 9.10 Karmic was the last version I could use the device with. I recently checked Ubuntu 11.04 Natty (coming with NetworkManager version 0.8.3.998). This too does not work, forcing me to stay with Karmic. From the status of the various bugs I got the idea that no one seems to care. Maybe only few users are affected. All the details are here: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/784573 or https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/459052 or https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/376361 Is there anything I can do (besides from learning to hack at NetworkManager ...) ?
