openwrt - uqmi

Customized uqmi with APN profiles. More information and source code: https://github.com/mrhaav/openwrt-packages/blob/main/README.md

Version 2022-09-13-0.9 includes an SMS receive and send function and a connectivity daemon. The SMS is stored in /var/sms/received and the file name is sent to script /usr/bin/uqmi_sms.sh. (uqmi_sms.sh is not included in the ipk file) The daemon will run every 30sec and check network connectivity and send the RSSI value to script /usr/bin/uqmi_led.sh to trigger signal strenght LEDs. (uqmi_led.sh is not included in the ipk file)
Don´t run other uqmi scripts in parallell. The modems are not able to handle multiple umqi request at the same time.
If you need some special uqmi command to be exequted every 30s, add them to the daemon, /usr/bin/uqmi_d.sh.

Switches:
uci set network.<your interface>.ipv6profile=<ipv6 profile number> If you need an other APN for IPv6. Configure you IPv4 APN with LuCI and add the IPv6 APN with uqmi command --create-profile or --modify-profile

uci set network.<your interface>.abort_search=false If you have you modem in poor radio coverage, you can let the modem search for network for ever (default, it will search for 35 sec).

uci set network.<your interface>.daemon=false If you would like to turn off the daemon.

Don´t foget to run uci commit network.
