Usage:
- Connection:
- Connect the VCC pin to a 3.3V to 5V power supply.
- Connect the GND pin to ground.
- Connect the TX pin of the module to the RX pin of the microcontroller.
- Connect the RX pin of the module to the TX pin of the microcontroller.
- Pairing:
- Power on the module; it will enter pairing mode, indicated by a flashing LED.
- Search for the module using a Bluetooth-enabled device (e.g., smartphone, tablet, PC) and pair with it. The default pairing code is usually "1234" or "0000."
- Once paired, the LED will stop flashing and remain on, indicating a successful connection.
- Communication:
- Use serial communication commands to send and receive data between the microcontroller and the paired device.
- Configure the module's settings (e.g., baud rate) if necessary using AT commands.
Caution:
- Ensure proper voltage levels to avoid damaging the module.
- Handle the module carefully to avoid static discharge and physical damage.
- Avoid placing the module near metal objects to maintain optimal signal strength.
