I tried the GSM.h sample code. (https://www.arduino.cc/en/Tutorial/GSMExamplesWebServer)
When I run the code, it output lots of error.

Did anyone try GSM.h before?

Thank you

I want to create a web server with my sim card. I search on the internet, but there is no example for sim800l. Most of the example are for WiFi or sim900, etc.

I want to command my M5stack (using SIM800) by sending a data from my computer with a simple website. So my M5Stack + Computer both can be connected to internet and my computer will be knowing the IP address of the Sim card.

Thank you

Hi

Now I'm trying the example code of GSM.h to set up a web server.

It output a lot of error

Anyone knows what happened? thank you

I have no idea. So i just force disconnect if the RSSI of the WiFi is too low.

@lastcaress

I'm using the example code from TinyGSM.h library.

@rop

Thank you.

I also want to ask that will it auto disconnect from the wifi when it is no internet access? Or I have to use WiFi.disconnect() to force it disconnect? when i walk too far from the router, it still connect to the wifi but cannot connect to internet

Is the M5Stack WIFI scan area larger than smartphone? When my smartphone cannot scan my wifi, M5stack still print that it can scan and connect to the wifi.

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.
