It is an application that allows you to connect the micro:bit Bluetooth UART. When you hit the keyboard of your smartphone, characters will be displayed on the LED of the micro:bit. Displays the characters sent from the micro:bit. In the sample, when the A button is pressed, Hello is sent and displayed on the smartphone. Usage 1. program the micro:bit 2. The micro:bit start and wait for Bluetooth connection (in the sample, a square mark is displayed) 3. Press the "connect to micro:bit" button in the app 4. When the connection is complete, the square display in the middle (transmission character display) will turn black and a check mark will appear on the micro:bit. 5. Hit the keyboard and the character will be displayed on the micro:bit 6. When you press the A button on the micro:bit, "Hello" is displayed in the "received message" part of the app 7. Press the "disconnect from micro:bit" button to disconnect Bluetooth and display a cross mark on the micro:bit
