I am doing a Farm Fire Detection Project where I need to use the sim800l v2.0 5V with arduino nano to connect to a thingspeak server. I have the flame detector part working but the sim800l does not seem to be able to connect to the cellular network as it blinks every 1s.(Yes, my sim card is inserted into the module.) I suspect it might be something to do with my 4g hotlink sim card but not to sure. Any advice and guidance welcomed. EggY0lk Networks and Broadband Sun, 05 Dec 2021 20:14:06 +0800
