Publisher Description

micro:bit Gateway -
Bluetooth data exchange for micro:bit devices

This app establishes a channel between two micro:bit devices. The channel will be handeled as UART communication. You have to develope a programm on each micro:bit device with UART transfer.

Indication aktive: BLE Indication (Default)
Indication inaktive: BLE Notification

Silent aktive: No visual logging
Silent inaktive: Logging

Requirements:
- Min. Android 4.4
- Bluetooth Low Energy (BLE)
- Paired devices
- micro:bit programm (developed by yourself)

MBED example:

#include "MicroBit.h"
#include "MicroBitUARTService.h"

MicroBit uBit;
MicroBitUARTService *uart;

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)
{
if (connected == 0) {
uBit.display.scroll("NC");
return;
}
uart->send("Yes");
uBit.display.scroll("Y");
}

void onButtonB(MicroBitEvent e)
{
if (connected == 0) {
uBit.display.scroll("NC");
return;
}
uart->send("No");
uBit.display.scroll("N");
}

void onButtonAB(MicroBitEvent e)
{
if (connected == 0) {
uBit.display.scroll("NC");
return;
}
uart->send("SK");
uBit.display.scroll("SK");
}

void processBLEUart() {
uint8_t readBuf[22];
while (1) { // loop for ever
if ((!connected) || (!uart->isReadable())) {
uBit.sleep(50); // wait 50mS and check again
continue; // loop;
}
//else we are connected AND there is some input to read
if (uart->isReadable()) {
while (uart->isReadable()) {
int charCount = uart->read(readBuf, 22, ASYNC);
if (charCount != 0) {
for (int i = 0; i < charCount; i++)
uBit.display.scroll((char) readBuf[i]);
}
}
}
}
}

IMPORTANT !!!
Oherwise you will run out of memory !
