Tutorial: How to Use the CC2540 Bluetooth Development Board

The CC2540 Bluetooth development board is ideal for those who want to create wireless devices with Arduino. It allows data communication between an electronic device and a smartphone or tablet, making wireless user interfaces possible.

What you need

• Arduino Uno
• Development software compatible (e.g. Arduino IDE)
• USB A-MicroB cable

Steps

1. Connect the CC2540 module to the laptop or PC via USB cable.
2. Install the Arduino BLE library from the development software package manager.
3. Load an example sketch provided by the library onto your Arduino Uno connected to the board.
4. Open the serial monitor and verify that the data is being sent correctly between the Arduino and the CC2540 board.

Example code

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

void loop() {
  if (Serial.available()) {
    String incoming = Serial.readString();
    BLE.sendData(incoming); // verifica sul datasheet per la funzione corretta
  }
}

Mini project

Create a home alarm system that sends a notification to the phone when a door or window is opened.
