If not please refer me to appropriate forums. I have a Quectel UC20 gsm modem. I got it working under Debian Jessie on my MacBook (using VirtualBox). It all seem to go well and had no problems getting it to work (well, after I unloaded the option driver, as the Quectel documentation only specifies the multiple tty method to access the modem). Now I have installed the same modem (on an evaluation board) to my embedded arm board (Digilent ZedBoard with Xilinx Zynq dual ARM-A9 SOC), also running Debian Jessie. It's conncected via a USB OTG port. It shows up with lsusb and also the /dev/cdc-wdm0 entry is populated. MM can see the device with 'mmcli -L' and 'mmcli -m 0' reports a bunch of information, so everything looks fine as far as detecting and communicating with the device. However, I just can't get it to connect to my ISP. It works ok on the full Debian Jessie system, but not on the ZedBoard. I copied the /etc/NetworkManager/system-connections/<myisp> file from the VB system. I presume that is ok and MM should work. I thought I would try creating a new connection, but I can't find a way of doing this from the cli. nm-connection-editor is gnome app and I don't have gnome installed on my embedded board. I tried nmtui, nmtui-edit, nmtui-connect, but there are no options to add a Mobile Broadband connection as there is with nm-connection-editor. Is there a nice/easy way of adding a new Mobile Broadband connection with the cli tools ? <blockquote><tt># cat /etc/NetworkManager/system-connections/Telstra\ Telstra\ \(Next\ G\)\ 1 [connection] id=Telstra Telstra (Next G) 1 uuid=5ee505f2-e161-436b-9b00-b36cab43ebfc type=gsm [gsm] number=*99# password-flags=1 apn=telstra.internet network-type=4 [ipv6] method=auto [ipv4] method=auto [serial] baud=115200 # lsmod</tt> <tt>Module Size Used by</tt> <tt>cp210x 7582 0 </tt> <tt>qmi_wwan 10608 0 </tt> <tt>cdc_wdm 8788 2 qmi_wwan</tt> <tt>usbnet 17174 1 qmi_wwan</tt> <tt>mii 3417 1 usbnet</tt> <tt>ipv6 262886 24 </tt> <tt># cat /boot/config-4.0.0-g0fa909f-dirty | grep -v '#' | grep 'WWAN\|QMI\|USB_SERIAL\|PPP\|QUALCOM'</tt> <tt>CONFIG_NET_VENDOR_QUALCOMM=y</tt> <tt>CONFIG_PPP=m</tt> <tt>CONFIG_PPP_BSDCOMP=m</tt> <tt>CONFIG_PPP_DEFLATE=m</tt> <tt>CONFIG_PPP_FILTER=y</tt> <tt>CONFIG_PPP_MPPE=m</tt> <tt>CONFIG_PPP_MULTILINK=y</tt> <tt>CONFIG_PPPOE=m</tt> <tt>CONFIG_PPP_ASYNC=m</tt> <tt>CONFIG_PPP_SYNC_TTY=m</tt> <tt>CONFIG_USB_NET_QMI_WWAN=m</tt> <tt>CONFIG_USB_SERIAL=y</tt> <tt>CONFIG_USB_SERIAL_GENERIC=y</tt> <tt>CONFIG_USB_SERIAL_CP210X=m</tt> <tt>CONFIG_USB_SERIAL_FTDI_SIO=y</tt> <tt>CONFIG_USB_SERIAL_PL2303=m</tt> <tt>CONFIG_USB_SERIAL_QCAUX=m</tt> <tt>CONFIG_USB_SERIAL_QUALCOMM=m</tt> <tt>CONFIG_USB_SERIAL_WWAN=m</tt> <tt>CONFIG_USB_SERIAL_OPTION=m</tt> </blockquote> </blockquote> <tt># mmcli -L </tt><tt> </tt><tt> </tt><tt>Found 1 modems:</tt><tt> </tt><tt> /org/freedesktop/ModemManager1/Modem/0 [QUALCOMM INCORPORATED] 0</tt><tt> </tt><tt> </tt><tt> # mmcli -m 0</tt><tt> </tt><tt> </tt><tt>/org/freedesktop/ModemManager1/Modem/0 (device id 'a6620fb85776960b03a5848959ac4607cf6922dc')</tt><tt> </tt><tt> -------------------------</tt><tt> </tt><tt> Hardware | manufacturer: 'QUALCOMM INCORPORATED'</tt><tt> </tt><tt> | model: '0'</tt><tt> </tt><tt> | revision: 'UC20GQAR03A05M1024 1 [2014/05/05 9:00:00]'</tt><tt> </tt><tt> | supported: 'gsm-umts'</tt><tt> </tt><tt> | current: 'gsm-umts'</tt><tt> </tt><tt> | equipment id: '861075020977922'</tt><tt> </tt><tt> -------------------------</tt><tt> </tt><tt> System | device: '/sys/devices/soc0/amba@0/e0002000.usb/ci_hdrc.0/usb1/1-1/1-1.4'</tt><tt> </tt><tt> | drivers: 'qmi_wwan'</tt><tt> </tt><tt> | plugin: 'Generic'</tt><tt> </tt><tt> | primary port: 'cdc-wdm0'</tt><tt> </tt><tt> | ports: 'cdc-wdm0 (qmi), wwan0 (net)'</tt><tt> </tt><tt> -------------------------</tt><tt> </tt><tt> Numbers | own : 'unknown'</tt><tt> </tt><tt> -------------------------</tt><tt> </tt><tt> Status | lock: 'sim-pin2'</tt><tt> </tt><tt> | unlock retries: 'sim-pin (3), sim-pin2 (3), sim-puk (10), sim-puk2 (10)'</tt><tt> </tt><tt> | state: 'connected'</tt><tt> </tt><tt> | power state: 'on'</tt><tt> </tt><tt> | access tech: 'umts'</tt><tt> </tt><tt> | signal quality: '68' (recent)</tt><tt> </tt><tt> -------------------------</tt><tt> </tt><tt> Modes | supported: 'allowed: 2g;

There must be a misconfiguration or something not installed, but I can't work out what it is. Thanks, Brendan. </blockquote> Er, it's now working. Why? Not sure. I had to try out a new SD card (Samsung with larger capacity, 32GB, as my Sandisk 32GB cards weren't working), so I recreated my rootfs, created the disk image, dd to sd card, booted, scp the NM system-configurations config file from VBox system to target board, restarted NM (not sure if I had too or not), and ifconfig shows me an assigned IP address :) So, not sure what the heck is going on, but maybe my running system was out of whack and just needed a reboot. I was installing some packages directly on the target with aptitude. Hopefully it's reliable and stable so that the IP connections always comes up on boot, and stays up. Fingers crossed :) Brendan. </body> </html>
