Instructions for Use:

1. Power Supply Connection:

   • Connect the VCC pin to a power supply within the operating voltage range (1.8V to 3.6V).
   • Ensure the GND pin is connected to the system ground.

2. UART Configuration:

   • The module uses UART interface for communication.
   • Connect the TXD and RXD pins to the corresponding pins on your microcontroller or host device.
   • Set baud rate according to the application requirements; default is usually 9600 bps.

3. Initialization:

   • Upon powering up, the module will initialize automatically.
   • For custom configurations, send AT commands via the UART interface.

4. Operating Modes:

   • Active Mode: For normal operation with higher power consumption.
   • Low Power Mode: To save power, switch to low power mode when not actively transmitting data.

5. Bluetooth Pairing:

   • Follow the pairing instructions specific to your application.
   • Typically involves making the module discoverable and then connecting from another Bluetooth device.

6. Antenna Considerations:

   • The module has a built-in chip antenna optimized for 2.4GHz operation.
   • Ensure there are no obstructions around the antenna area for optimal performance.

7. Environmental Conditions:

   • Operate within the specified temperature ranges to avoid damage or malfunction.
   • Store in a dry place away from extreme temperatures when not in use.

8. Handling Precautions:

   • Handle with care to avoid static discharge which can damage sensitive components.
   • Avoid exposing the module to water or corrosive substances.
