Applications:

• Wireless serial communication
• Home automation systems
• Remote control systems
• Data acquisition systems
• Wireless sensors
• Robotics and DIY projects
• Wireless data logging

Usage:

1. 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.
2. 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.
3. 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.
