    • RE: HOWTO: M5Stack with GPS, GSM and LoRa, all at the same time

      I think i've found the issue,
      I think when the LoRa.begin function is called it is locking up the SPI so that it then can't talk to it, but on the next time round the loop the screen's SPI.begin is being called again so is able to access it and draw to the screen

    • RE: USB Device not recognised

      Wow! haha, just found the most weirdest solution,
      not sure if the USB port in the M5 stack is wired properly,
      If I turn the USB C cable around then it works, so it seems like the cable has to be a certain direction for it to work, I have even tested this with multiple cables all with the same result!, so if it's not working try rotating your cable!

      Hi rop,
      When I run your code the screen is completely white,
      but If i press the A button (button far left), it looks like it refreshes the screen and then the text is displayed?, weirder and weirder haha

      I have had issues with my M5 Stack keep popping up on windows with USB device not recognised, so wonder if somehow they are related, is a bit strange

      Hi Rop,

      I have tried pushing a little harder on it but didn't change anything.

      On the serial port i'm getting:
      "Testing LoRa ...
      Init Succeeded
      Reset line works"

    • White screen when using LoRa module

      Hello everyone, when I try to use the LoRa module i'm just getting a completely white screen.
      The code i'm using is:

      #include <M5Stack.h>
      #include <M5LoRa.h>

      void setup() {

      M5.begin();

      // override the default CS, reset, and IRQ pins (optional)
      LoRa.setPins(); // default set CS, reset, IRQ pin
      Serial.println("LoRa Receiver");
      M5.Lcd.println("LoRa Receiver");

      // frequency in Hz (433E6, 866E6, 915E6)
      if (!LoRa.begin(433E6)) {
      Serial.println("Starting LoRa failed!");
      M5.Lcd.println("Starting LoRa failed!");
      while (1);
      }

      // LoRa.setSyncWord(0x69);
      Serial.println("LoRa init succeeded.");
      M5.Lcd.println("LoRa init succeeded.");
      }

      void loop() {
      // try to parse packet
      int packetSize = LoRa.parsePacket();
      if (packetSize) {
      // received a packet
      Serial.print("Received packet: "");
      M5.Lcd.print("Received packet: "");

      // read packet
      while (LoRa.available()) {
        char ch = (char)LoRa.read();
        Serial.print(ch);
        M5.Lcd.print(ch);
      }
      
      // print RSSI of packet
      Serial.print("\" with RSSI ");
      Serial.println(LoRa.packetRssi());
      M5.Lcd.print("\" with RSSI ");
      M5.Lcd.println(LoRa.packetRssi());
      

      }
      }

      not sure how to add a code tag sorry.
      I have tried swapping the LoRa RST and INT pins according to someone on the forum to make the LoRa work, the LoRa seems to be working okay but the screen is just completely white.

    • RE: HOWTO: M5Stack with GPS, GSM and LoRa, all at the same time

      Just used your code to test with a LoRa module.
      I just have the black M5 Stack and the LoRa module, but the screen goes white when I have the LoRa module attached?

    • RE: USB Device not recognised

      I have just tried taking the bottom section off (the section with the battery in it) and it seems to be working fine now, as soon as I put that bottom section back on it doesn't work again, so strange....

      I have tried it on multiple computers and they are all coming up in device manager with "Windows has stopped this device because it has reported problems. (Code 43)
