Instructions for Use:
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.
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.
Initialization:
- Upon powering up, the module will initialize automatically.
- For custom configurations, send AT commands via the UART interface.
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.
Bluetooth Pairing:
- Follow the pairing instructions specific to your application.
- Typically involves making the module discoverable and then connecting from another Bluetooth device.
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.
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.
Handling Precautions:
- Handle with care to avoid static discharge which can damage sensitive components.
- Avoid exposing the module to water or corrosive substances.
