how to get my Lte modem to auto connect on boot up using QMI interface using libqmi
Hi @bazil747,
Try to use these qmicli commands to get/set the settings:
--wds-get-autoconnect-settings : Get autoconnect settings
and:
--wds-set-autoconnect-settings=[(enabled|disabled|paused)[,(roaming-allowed|home-only)]] : Set autoconnect settings (roaming settings optional)
Examples:
qmicli -d /dev-cdc-wdm0 --wds-get-autoconnect-settings
qmicli -d /dev-cdc-wdm0 --wds-set-autoconnect-settings=enabled,home-only
or create your own service using systemd.
Thank you.
Hi @ensar,
Thank you for your answer, regarding this, when my raspi boots it runs the script which initializes wwan0 with a 10.111.100.X ip address. Once the system is working fine, if the equipment where the raspi is mounted goes through a zone where there is not good GMS signal wwan0 loses the configuration and returns to a 192.X.X.X ip address, result: zero internet connection after that. I’ve noticed in the script the –wds-set-autoconnect-settings=disabled, if I change it as you recommend, when the raspi gets again to a zone with signal, will it recover the wwan0 initial configuration or do I have to run a systemd script that identifies the “problem” and re-run the initial script in order to get my configuration back? Thank you in advance. Here is the script run at boot in case it help you understand, thank you in advance.
