Peripheral Examples

LTE Data (TinyGSM)

#define TINY_GSM_MODEM_SIM7600
#include <TinyGsmClient.h>

// SIM7600E UART: RX=26, TX=27, PWR_KEY=4
HardwareSerial modemSerial(1);
TinyGsm modem(modemSerial);

void setup() {
  Serial.begin(115200);
  modemSerial.begin(115200, SERIAL_8N1, 26, 27);
  // Power on modem
  pinMode(4, OUTPUT);
  digitalWrite(4, HIGH); delay(1000);
  digitalWrite(4, LOW);  delay(2000);

  modem.restart();
  Serial.println("Modem: " + modem.getModemInfo());
  modem.gprsConnect("your.apn", "", "");
  Serial.println("GPRS connected: " + String(modem.isGprsConnected()));
}

void loop() { delay(1000); }

GPS (SIM7600E built-in GNSS)

#define TINY_GSM_MODEM_SIM7600
#include <TinyGsmClient.h>

HardwareSerial modemSerial(1);
TinyGsm modem(modemSerial);

void setup() {
  Serial.begin(115200);
  modemSerial.begin(115200, SERIAL_8N1, 26, 27);
  modem.enableGPS();
  Serial.println("GPS enabled");
}

void loop() {
  float lat, lon, speed, alt;
  int vsat, usat;
  if (modem.getGPS(&lat, &lon, &speed, &alt, &vsat, &usat)) {
    Serial.printf("Lat: %.6f Lon: %.6f Alt: %.1f\n", lat, lon, alt);
  }
  delay(2000);
}

FAQ

Q: Modem not responding?
A: Insert a valid SIM card. Connect 4G and GPS antennas. Power on the SIM7600E module using the PWR_KEY GPIO.

Q: Which region does SIM7600E cover?
A: SIM7600E is the European variant supporting LTE Cat-4, WCDMA, and GSM for European/Middle Eastern/African bands.
