Bluetooth

Support for additional Bluetooth services.

For another device like a smartphone to use any of the Bluetooth “services” which the micro:bit has, it must first be paired with the micro:bit. Once paired, the other device may connect to the micro:bit and exchange data relating to many of the micro:bit’s features.

bluetooth.startAccelerometerService();
bluetooth.startButtonService();
bluetooth.startIOPinService();
bluetooth.startLEDService();
bluetooth.startMagnetometerService();
bluetooth.startTemperatureService();
bluetooth.onBluetoothConnected(() => {});
bluetooth.onBluetoothDisconnected(() => {});
bluetooth.setTransmitPower(7);

UART

bluetooth.startUartService();
bluetooth.uartReadUntil("");
bluetooth.uartWriteLine("");
bluetooth.uartWriteString("");
bluetooth.uartWriteNumber(0);
bluetooth.uartWriteValue("", 0);
bluetooth.onUartDataReceived(",", () => {})

Eddystone

bluetooth.advertiseUid(42, 1, 7, true);
bluetooth.advertiseUrl("https://makecode.microbit.org/", 7, true);
bluetooth.stopAdvertising();
