Features

• Bluetooth Low Energy (BLE) Connection
• Compatible with Arduino
• SKU: ARD0011756
• Price: 45 €

What it is for

The Bluetooth BLE Shield is ideal for projects requiring wireless communication between Arduino and Bluetooth devices. Some examples of usage include:

• Remote monitoring systems
• Bluetooth user interfaces
• Wireless data transfer

Compatibility with Arduino allows for easy integration into projects based on this platform.

Tutorial: How to use Bluetooth BLE Shield

The Bluetooth BLE Shield allows you to connect your Arduino project to Bluetooth devices, facilitating cable-free data transfer. Useful for projects requiring Bluetooth connectivity, such as monitoring systems or user interfaces.

What you need

• Arduino UNO or compatible
• USB cable for power supply
• Bluetooth BLE Shield board
• Bluetooth antenna (optional)
• Computer for code upload
• Bluetooth BLE library for Arduino

Steps

1. 1. Installation: Download and install the Bluetooth BLE library for Arduino.
2. 2. Connection: Connect the Bluetooth BLE Shield board to your Arduino UNO.
3. 3. Antenna: If necessary, mount the Bluetooth antenna on the back of the board.
4. 4. Configuration: Configure the Bluetooth settings in the Arduino code.
5. 5. Upload: Upload the code to the Arduino.
6. 6. Test: Activate the Bluetooth connection on your smartphone and try to send data.
7. 7. Debug: Check the datasheet for any additional specifications you may need.
8. 8. Customization: Adapt the code to your specific needs.

Example code

```void setup() {  BLEDevice::init("MyDevice");  BLEServer *pServer = BLEDevice::createServer();  BLEService *pService = pServer->createService(BLEUUID("6E400001-B5A3-F393-E0A9-E50E24DCCA9E"));  BLECharacteristic *pCharacteristic = pService->createCharacteristic(  BLEUUID("6E400002-B5A3-F393-E0A9-E50E24DCCA9E"),  BLECharacteristic::PROPERTY_READ | BLECharacteristic::PROPERTY_WRITE);  pCharacteristic->setValue("Hello, World!");  pService->start();  BLEAdvertising *pAdvertising = BLEDevice::getAdvertising();  pAdvertising->addServiceUUID(pService->getUUID());  pAdvertising->start();}void loop() {}```

Mini project

Create a simple step counter using a PIR sensor and send the data to your smartphone via Bluetooth BLE.

Common mistakes
