FW: QMICLI tools examples and documentation for begginers

[dominik.lastovcic at x-logic.net]

Thank you for your quick response Aleksander. This is the set of commands I use for setting up the network. 

 

sudo qmicli -p -d /dev/cdc-wdm0 --dms-set-operating-mode='online'

sudo ip link set wwan0 down

echo 'Y' | sudo tee /sys/class/net/wwan0/qmi/raw_ip

sudo ip link set wwan0 up

sudo qmicli -p -d /dev/cdc-wdm0 --device-open-net='net-raw-ip|net-no-qos-header' --wds-start-network="apn='m2m.tele2.com',ip-type=4" --client-no-release-cid

sudo udhcpc -S -n -i wwan0 (-S = log to sysfile, -n = exit if lease not obtained)

 

 

These commands are executed every time the wwan0 interface can’t ping 8.8.8.8

 

The problem I faces with running these commands in a loop was CID exhaustion. Do you think I could simply avoid that problem with restarting the modem every time it is unable to ping?

I have tried:

 

sudo qmicli -p -d /dev/cdc-wdm0 --dms-set-operating-mode='reset'

 

But sometimes I get this error:

 

couldn't create client for the 'dms' service: CID allocation failed in the CTL client: Transaction timed out

 

Is there a better way to restart the modem?

 

If you could help me on this topic it would mean a lot.

 

Thank you.

 

Best regards,

Hey Dominik,

 

 

I am currently working with Simcom SIM7500E module and I am using qmicli to set the network for the modem. Could you please recommend me a good guide for beginners who work with qmicli commands? I have read the qmicli man page and I have seen some examples from forums on how to use the commands, but I haven’t found that detailed enough.

 

 

I agree there is not much documentation or many examples on how to use qmicli; who has time for that? :P

 

A good example on how to use qmicli, e.g. with the options to allocate CIDs once and reuse them over and over, is the qmi-network program itself:  <https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/blob/master/utils/qmi-network.in> https://gitlab.freedesktop.org/mobile-broadband/libqmi/-/blob/master/utils/qmi-network.in

 

Other than that, I'm not sure there are other public examples that make use of qmicli.

 

If anyone would like to work on documenting qmicli or adding some step-by-step examples on how to use it, please do so by collaborating in the  <http://modemmanager.org> modemmanager.org doc website contents:  <https://modemmanager.org/docs/libqmi/> https://modemmanager.org/docs/libqmi/ Anyone can send merge requests for that website here:  <https://gitlab.freedesktop.org/mobile-broadband/mobile-broadband.pages.freedesktop.org> https://gitlab.freedesktop.org/mobile-broadband/mobile-broadband.pages.freedesktop.org
