micro:bit UART Terminal

This app communicates between Android and a micro:bit device. You can transmit and receive text in 'notification' or 'indication' mode. The UART communication also has to be implemented at the micro:bit device (Block, Javascript, MBED). Options: - Indication: Default micro:bit mode (otherwise notification mode) - LF: Linefeed added - CR: Carriage return added Requirements: - Min. Android 5 - Bluetooth Low Energy (BLE) - Paired devices - micro:bit programm (developed by yourself) V 2.1: Copy to Clipboard (Option Menu) V 2.2: Clear List (Option Menu), No Log Option V 2.5: Hex Mode MBED example: #include "MicroBit.h" #include "MicroBitUARTService.h" #include "BMP180.h" MicroBit uBit; MicroBitUARTService *uart; BMP180 bmp180(P0_30, P0_0); char buffer[80]; float pressure,temperature; int connected = 0; void onConnected(MicroBitEvent e) { uBit.display.scroll("C"); connected = 1; } void onDisconnected(MicroBitEvent e) { uBit.display.scroll("D"); connected = 0; } void onButtonA(MicroBitEvent e) { uBit.display.scroll(buffer); } void onButtonB(MicroBitEvent e) { uBit.display.scroll("SK"); } /* IMPORTANT !!! Oherwise you will run out of memory !
