    • RE: How to create a server with sim800l module?

      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

    • How to create a server with sim800l module?

      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

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

      @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

    • Quest about WIFI connection

      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.

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

    • 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:
      https://www.arduino.cc/en/Guide/ArduinoGSMShield
      https://www.ayomaonline.com/programming/quickstart-sim800-sim800l-with-arduino/

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

      Thank you.

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

      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?
