<![CDATA[Question about M5Stack Sim800L Module]]>I'm now trying to use the sim800L Module (https://www.elektor.com/m5stack-sim800l-gsm-module).

I want to check whether the sim card can connect to network.

However, I cannot check whether the sim card have network function.

I had visit different website and use tinyGSM but still can't fix the problem. Can anyone give me some tips?

The websit I had read:

I don't know why after I upgrade the arduino from 1.8.5 to 1.8.7, and then I can get the result.
