    • M5Stack LTE module(M8321) initialization and time synchronisation

      Does anyone have any clue how to get the LTE module to connect to an LTE network and synchronise the time?

      I have been attempting sending different AT commands to the modem, however I haven't been able to successfully connect to the network.

      Cheers everyone.

    • M5Stack LTE module(M8321) not communicating or responding to serial commands?

      I'm trying to get it working at the moment, however no luck so far. From the schematic i've deduced that its operating as a generic modem, with a basic serial connection from the core to the LTE module on GPIO pins 16 and 17. However when attempting to send modem AT commands there is no response from the module?

      I am programming this in arduino, and I have set up a very simple sketch to send the commands from the stack to the LTE module

      #include <M5Stack.h>

      void setup() {
      Serial.begin(9600); // set up serial
      Serial2.begin(9600, SERIAL_8N1, 16, 17); // set up a second serial that will comunicate directly with the LTE shield

      //set pin 2 high for using the modem (simulates a power button press)
      pinMode(2, OUTPUT);
      digitalWrite(2, 0);
      delay(3000);
      digitalWrite(2, 1);
      }

      void loop() {

      while (Serial.available()){  // forward data from monitor to LTE module
        uint8_t recieve = Serial.read();
        Serial2.write(recieve);
      }
      
      while (Serial2.available()){  // forward data from LTE module to monitor
        Serial.write(Serial2.read());
      }
      

      }

      I then manually input the AT commands and wait for a response from the board, however there is no response.
