Icera probing fixes
Last modified: 2014-10-14 12:27:29 UTC
The Icera probing needs some fixes to correctly handle the Nokia 21M-02. It needs to extend the AT timeout of the command, plus add some retry logic as the device may initially return ERROR to the AT%IPSYS? command. See: https://mail.gnome.org/archives/networkmanager-list/2014-February/msg00064.html
FWIW I've found a reliable way to make MM detect my modem as an Icera-based one: pkill -STOP ModemManager <plug in modem, wait for usb_modeswitch and then for it to settle> pkill -CONT ModemManager That suggests to me that retries and extended timeouts will do the trick. Tore
Yeah, I had the same issue, if the modem is plugged in before MM runs, then it all works. Hotplugging the modem while MM is running fails... I'm now able to reproduce Tore's issue locally with my 21M.
Moving bugreport to the new ModemManager bugzilla in fd.o; summarized the issue there as well. Please subscribe to the new bugreport to get new updates. https://bugs.freedesktop.org/show_bug.cgi?id=84993 Closing this report as NOTGNOME.
