Tutorial: How to use RF-BM-S01 Bluetooth Ble4.0 Module

The RF-BM-S01 Bluetooth BLE4.0 module is a wireless communication device that allows Arduino devices and other microcontrollers to connect to other Bluetooth devices or smartphones to transfer data. This module is ideal for remote control projects, sensor monitoring, and mobile app interactions.

What you need

• Arduino Uno or compatible
• USB A-MicroB cable
• Arduino IDE software installed

Steps

1. Connect the RF-BM-S01 module to the Arduino serial interface using GPIO cables.
2. Open the Arduino IDE and load a sample sketch to test the Bluetooth connection.
3. Verify that the device is detected by the computer or smartphone through the dedicated application.
4. Configure the module settings through the software library installed in Arduino IDE.

Example code

// Includi la libreria per il modulo
#include <SoftwareSerial.h>

// Definisci i pin di connessione
#define RX 2
#define TX 3

SoftwareSerial BTserial(RX, TX);

void setup() {
  Serial.begin(9600);
  BTserial.begin(9600);
}

void loop() {
  if (BTserial.available())
    Serial.write(BTserial.read());
  if (Serial.available())
    BTserial.write(Serial.read());
}

Mini project
