I posted a bug report on upstream bug tracker, too. https://bugzilla.gnome.org/show_bug.cgi?id=622576
I discussed with Dan Williams, a maintainer. He asked me about AT+GCREG. Can you try follows on ADU 635? I have an OEM of ADU 635, NTT A2502. It may not have same behavior than ADU 635. Try connect with 'seyon' '$ seyon -modems /dev/ttyUSB0' and then type on the serial terminal 'AT+GCREG?' and 'AT+CREG?' ** Bug watch added: GNOME Bug Tracker #622576 https://bugzilla.gnome.org/show_bug.cgi?id=622576 -- modem manager anydata adu 635 https://bugs.launchpad.net/bugs/569685 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
