Introduction to UART Read
The UART Read feature allows micro:bit devices to communicate with other Bluetooth-enabled devices, such as smartphones, by reading data sent over the Bluetooth UART service. This service enables the exchange of data in small chunks, making it ideal for applications that require real-time data transfer.
Key Features:
- Bluetooth Pairing: Before using the UART service, devices must be paired to establish a secure connection.
- Data Reading: The micro:bit can read incoming data until a specified delimiter character is encountered, allowing for flexible data handling.
- Real-time Interaction: Ideal for applications like games or data logging where immediate feedback is necessary.
Use Cases:
- Smartphone Applications: Create apps that interact with the micro:bit for educational purposes or fun projects.
- Data Logging: Use the micro:bit to collect data from sensors and send it to a smartphone for analysis.
- Interactive Games: Develop games that utilize Bluetooth communication for multiplayer experiences.
