wget https://github.com/mrhaav/openwrt/raw/master/21.02.3/uqmi_2022-05-16-0.5_mipsel_24kc.ipk
opkg install uqmi_2022-05-16-0.5_mipsel_24kc.ipk

uqmi version 2022-04-22-0.5 and 2022-05-16-0.5 includes a daemon that will check the connection every 30sec. If the connection is released from the network, the daemon will re-connect the interface.

This daemon will also send the rssi value to /usr/bin/uqmi_led.sh for trigger signal strength LEDs. When the daemon is stoped it will send rssi value = -200 to turn off all LEDs.

An SMS receiver will store received SMS in /var/sms folder. The daemon will send the file name to /usr/bin/uqmi_sms.sh. The first row in the SMS file is the senders phone number and the following rows are the text message.

uqmi_led.sh and uqmi_sms.sh are not included in the ipk file. You need to create the files your self and make them executable, chmod +x <file_name>.
