Tutorial: How to Use GPRS/GSM A6 Pro Module

The GPRS/GSM A6 Pro module allows you to connect to the internet via the cellular network, enabling your Arduino projects to send and receive data at any time. Ideal for beginners who want to create connected devices.

What you need

• Arduino Uno or compatible
• GPRS/GSM A6 Pro module
• USB Type B to micro USB cable
• SIM card

Steps

1. Connect the GPRS/GSM A6 Pro module to the Arduino serial interface.
2. Install the GsmModem.h library in the Arduino package manager.
3. Load the example sketch provided with the library onto the Arduino.
4. Insert a valid SIM card into the module.
5. Check the datasheet for the power supply pin of the module and connect it to 3.3V or 5V of the Arduino.
6. Open the serial monitor in Arduino IDE and check that the module connects correctly to the GSM/GPRS network.
7. Modify the sketch to send a test SMS or make a test call.
8. Check the datasheet for specific commands of the module for advanced functions.

Example code

// Esempio di codice minimo
#include <GsmModem.h>

SoftwareSerial gprsSerial(2, 3); // RX | TX
GsmModem gprs(gprsSerial);

void setup() {
  Serial.begin(9600);
  gprs.begin(19200);
}

void loop() {}

Mini project

Create a home alarm system that sends an SMS notification when activated.
