uqmi version 2022-04-22-0.5 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.
