    • Sending Multiple data using LoRa module

      Hi,

      Was wondering if it is possible to send multiple variable data via LoRa?

      I am planning to send the data taken by the ENV module, e.g. temp, humidity and pressure. To test the system.

      I have tried combining all the data into one string, but I believe that it is not the right way to approach it, could use the help to figure out other solutions! Thanks!

      p.s. all done on arduino IDE so it would be great if responses are based on the arduino IDE.

    • RE: M5Stack LoRa and ThingSpeak

      So, I have 2 m5stack core with me.

      My idea is to have these 2(or potentially more) to communicate with each other via LoRa, one to be a sensor node, and another acts as a receiver.

      The receiving node will then upload the data received from the sensing node to thingspeak.

      The components used in this system is the ENV sensor, and the LoRa modules.

      I hope this explains what I am trying to do.

    • M5Stack LoRa and ThingSpeak

      Hello,

      I am trying to upload data to thingspeak that is being received from the LoRa Unit via Arduino, but so far all I have been able to upload are data that is irrelevant.

      The Arduino example shows that on the receiving end of LoRa, there is a line where the M5 read the packet sent, but simply uploading the said packet does not work, and ends up with 48/50.

      Said Code section is :
      while (LoRa.available()) {
      char ch = (char)LoRa.read();
      Serial.print(ch);
      M5.Lcd.print(ch);
      int x = ThingSpeak.writeField(myChannelNumber, 1, ch, myWriteAPIKey);
      if(x == 200){
      Serial.println("Channel update successful.");
      delay(10000);
      }
      else{
      Serial.println("Problem updating channel. HTTP error code " + String(x));
      delay(10000);
      }

      Is there anyway to upload that data? Thanks!

    • M5Stack LCD Auto Clear

      Hi,

      I was wondering if there was a feature within arduino/the M5Stack library that will allow me to AutoClear the LCD on the m5stack.

      I was thinking of attempting to scan/detect the cursor position on the m5stack, but have no idea how its supposed to be done.

      Any help would be greatly appreciated. Thanks!

    • MQTT Library for Arduino

      Hi,

      I have been looking around for a MQTT library for Arduino to use on the m5stack.

      I have stumbled upon the PubSubClient, and tried an example for SimpleMQTT via the ESP32 Examples on Arduino.

      Unfortunately, I do not have any knowledge on using AzureIoTHub and I am not sure what I need to configure the SimpleMQTT example.

      Is there a more simplified version of the MQTT library that's compatible with the m5stack? If not, is anyone able to advise me on how to set up the use of AzureIoTHub via the "SimpleMQTT" example?

      Thanks!
