help needed to use a Sierra Wireless MC7354 3G modem with a Raspberry Pi3 running Angstrom v2016.12 - Kernel 4.4.35



Hello Aleksander,

 

Thank you for directing me to the NetworkManager mailing list.

 

Here is my situation.

I want to use NetworkManager to create a 3G connection using ModemManager and the qmi_wann driver.

libqmi 1.16.0

mmcli 1.6.4

nmcli 1.0.12

 

I have had success issuing the commands below along with other commands using mmcli and qmicli.

qmicli -d /dev/cdc-wdm0 --wds-start-network=apn='apn=mnet.bell.ca.ioe'  --client-no-release-cid

mmcli -m 0

mmcli -m 0 --simple-connect="apn=mnet.bell.ca.ioe"

 

I think the problem lies with NetworkManager:

root@raspberrypi3:/# nmcli con show

NAME                UUID                                  TYPE            DEVICE

Wired connection 1  bdc6b7b3-1e60-453c-bfca-11ce7519826d  802-3-ethernet  eth0  

cellular            bd4fbd79-329c-4af2-a68d-a330df553abd  gsm             --    

root@raspberrypi3:/#

 

cellular was created with:

nmcli connection add type gsm con-name cellular ifname wwan0 apn mnet.bell.ca.ioe

 

But my wwan0 interface shows “unmanaged” and I cannot bring it up:

root@raspberrypi3:/# nmcli con up cellular ifname wwan0

Error: device 'wwan0' not compatible with connection 'cellular'.

root@raspberrypi3:/#

root@raspberrypi3:/# nmcli device status

DEVICE  TYPE      STATE      CONNECTION        

eth0    ethernet  connected  Wired connection 1

lo      loopback  unmanaged  --                

wwan0   wwan      unmanaged  --


The newly created cellular connection appears in system-connections:

root@raspberrypi3:/etc/NetworkManager/system-connections# ls

cellular

root@raspberrypi3:/etc/NetworkManager/system-connections# 


Interesting, the eth0 Wired connection 1 is not shown in that directory, nor can I find a definition for it. An interfaces file does not exist.

root@raspberrypi3:/# find . -iname "interfaces"

root@raspberrypi3:/#

 

If you are available to assist I would appreciate hearing back from you.

 

Many thanks!

- Phil
