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.
https://www.arduino.cc/en/Tutorial/GSMExamplesWebServer

It output a lot of error

Anyone knows what happened? thank you

@rop @ajb2k3

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.

@lastcaress @Rop
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.

@lukasmaximus

Thank you. I will try it again after buying the wire

@ajb2k3
Haha, it's fine. I almost give up trying the angle sensor myself. Now I'm trying to use the SIM800L GSM module.

@lukasmaximus

Thank you. But i just have this wire and I use your code still unsuccess.

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:

@ajb2k3

I had tried before. The output of 36 is similar to 39.

@ajb2k3
Thank you.

I had tried. There is no change when i steer the sensor, but the value will sometime auto change itself.

@ajb2k3
Thank you.
Do you mean changing "#define ROTARY_ANGLE_SENSOR 22" to "#define ROTARY_ANGLE_SENSOR 21"?

I changed 22 to 21 but there is no difference except digitalread() of 21 is always 1.

@ajb2k3
Yes, the white thing is the angle sensor and i connect it to the M5 Core. The Digitalread returns is 1.

I had tried analogread() on 22 but cannot get the angle change on the serial monitor (Its always 0).

Do you have any ideas?

@ajb2k3
Okay... Thanks a lot!
