Introduction to Bluetooth UART Service
The Bluetooth UART service allows devices like smartphones to communicate with the micro:bit, enabling data exchange through a serial interface. This service requires the micro:bit to be paired with the device before any data can be exchanged. Once connected, the micro:bit can send and receive data in chunks of up to 20 bytes, utilizing a buffer to manage incoming data until it is full. This flexibility allows for various applications, such as creating interactive games or transmitting sensor data.
Key Features:
- Data Exchange: Enables two-way communication between micro:bit and other Bluetooth-enabled devices.
- Buffer Management: Utilizes a 60-byte buffer to accumulate incoming data.
- Customizable Delimiters: Allows the use of special characters to signify the end of a message.
Use Cases:
- Interactive Games: Create games where questions and answers are exchanged between the micro:bit and a smartphone.
- Data Transmission: Connect sensors or cameras to transmit data over Bluetooth, enhancing the micro:bit's capabilities.
- Flexible Applications: The UART service can be adapted for various projects, making it a versatile tool for developers and educators alike.
