On Data Packet Received
The On Data Packet Received feature allows users to execute a part of their program when the micro:bit receives a data packet over radio. This is particularly useful for applications that require communication between multiple micro:bit devices. The API has been deprecated, and users are encouraged to use alternative methods for receiving strings and numbers.
Key Features:
- Receive Data: Trigger actions based on received numbers or strings.
- Callback Parameters: Access detailed information about the received packet, including the number, string, time, and signal strength.
- Troubleshooting: Guidance on setting up the radio group for successful communication.
Use Cases:
- Interactive Projects: Create games or applications where multiple micro:bits communicate with each other.
- Data Collection: Use the micro:bit to gather data from various sensors and transmit it wirelessly.
