Program your own LEGO Mindstorms EV3 Bluetooth Advanced RemoteControl.

Bluetooth Remote Control for colorinformation. 3 colors are handled either as text or bytes. 6channels for colors will be managed.The range of the values are between 0 and 255.Byte Mode (Default): Channel and 3 colors are transfered as 4bytesExample for BLUE and channel 2: 0x020000FFASCII Mode: Starting with the channel and a colon 3 colors aretransfered as text seperated by comma (ended by \n)Example for RED and Channel 1: "1:255,0,0\n"The purpose of the app is to control remote hardware likeArduino, Netduino, Raspberry Pi ...Version 1.1: Byte Mode Default

This app communicates between Android and a micro:bit device. Youcan transmit and receive text in 'notification' or 'indication'mode. The UART communication also has to be implemented at themicro:bit device (Block, Javascript, MBED). Options: - Indication:Default micro:bit mode (otherwise notification mode) - LF: Linefeedadded - 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) V2.2: Clear List (Option Menu), No Log Option V 2.5: Hex Mode MBEDexample: #include "MicroBit.h" #include "MicroBitUARTService.h"#include "BMP180.h" MicroBit uBit; MicroBitUARTService *uart;BMP180 bmp180(P0_30, P0_0); char buffer[80]; floatpressure,temperature; int connected = 0; voidonConnected(MicroBitEvent e) { uBit.display.scroll("C"); connected= 1; } void onDisconnected(MicroBitEvent e) {uBit.display.scroll("D"); connected = 0; } voidonButtonA(MicroBitEvent e) { uBit.display.scroll(buffer); } voidonButtonB(MicroBitEvent e) { uBit.display.scroll("SK"); } /*IMPORTANT !!!
