Title: GSM sim 800L v2 EVB
Post by: Nemac on Jul 18, 2019, 08:56 pm
Can someone help please..

I am working on project where I need to call sim800L module, It need to hang up and then send me a sensor state. I found many video but none can help. In my code I put to send me a message. I can not find the way how to read call state. I am new to all this so I am using GSM.h library. I can make it to call me, send sms and all. But no metter what library I use, my serial monitor never returns commands (I type AT, it's not shown on serial monitor)

On the serial monitor, we usually wait to get a module response to our AT commands.
If you want to send manual AT Command, find a tutorial on how to send manual AT Command.
