Application with Arduino

• This example shows how to communicate with the 7Semi EG800AK-CN PICO LTE module using an Arduino UNO. The Arduino works as a USB-to-UART bridge, allowing AT commands typed in the Arduino IDE Serial Monitor to be sent directly to the EG800 module.

#include <SoftwareSerial.h>

SoftwareSerial eg800(2, 3);   // RX, TX

void setup()
{
  Serial.begin(115200);      // Serial Monitor
  eg800.begin(115200);       // EG800 Module

  Serial.println("EG800 Ready");
  Serial.println("Type AT commands below...");
}

void loop()
{
  // EG800 -> Serial Monitor
  while (eg800.available())
  {
    Serial.write(eg800.read());
  }

  // Serial Monitor -> EG800
  while (Serial.available())
  {
    eg800.write(Serial.read());
  }
}
