@@AhmadLogs I don’t think it resets with under voltage warning URC, it resets when it receives the under voltage power down URC as it powers down and when voltage comes back up it try’s to connect to network and you have to reinitialise it, i.e. send AT to communicate over serial. Well that’s from my testing anyway.

@@AhmadLogs You could do a video on handling low battery situations, your videos are very good. You should pick up the “UNDER VOLTAGE WARNNING” (notice the 2 “N” misspelling, that’s what the module reports) URC then you can sent the recipient an sms warning the battery is getting low. Then when the module reports the “UNDER VOLTAGE POWER DOWN” URC the microcontroller has to enter a low power state and knows it has to setup the modem when turns back on when battery is charged. This is where I am in my project too. I use the Sim800L RI pin to interrupt a 3.3v pro mini int1 pin, my project is low power so the Sim800L is in sleep mode (AT+CSCLK=2) and when it receives a call or sms it sends RI pin low and wakes pro mini from Deep Sleep Power Down (interrupt) then processes the incoming data/message and acts on what’s sent. To make the RI pin from sin800l interrupt/wake the microcontroller when the under voltage URC messages are sent you first need to configure the Sim800L by sending AT+CFGRI=1, 1= on, 0=off when on and battery low, it sends the “UNDER VOLTAGE WARNNING” every 5 seconds (from memory) and keeps waking the microcontroller, after I have received the warning I send the command AT+CFGRI=0 to turn off interrupt and send low battery warning message then enter a low power sleep state until battery is charged. It would be great to see this in a video, there aren’t any on KZitem it seems displaying this situation and I would think it’s critical with a remote battery powered project using Sim800L. Hope this helps and sparks your interest in this area of your project.
