I'm developing an Android app that sends a string with ola value over bluetooth.
How do I send ola through bluetooth to a specific address like 00:00:00:00:00:00 ?
A function that sends a string through bluetooth to a specific address would be a great help.
Hello, good friend!
Try this:
private OutputStream outputStream;
private InputStream inStream;
private void init() throws IOException {
BluetoothAdapter blueAdapter = BluetoothAdapter.getDefaultAdapter();
if (blueAdapter != null) {
if (blueAdapter.isEnabled()) {
Set<BluetoothDevice> bondedDevices = blueAdapter.getBondedDevices();
if(bondedDevices.size() > 0){
BluetoothDevice[] devices = (BluetoothDevice[]) bondedDevices.toArray();
BluetoothDevice device = devices[0];
ParcelUuid[] uuids = device.getUuids();
BluetoothSocket socket = device.createRfcommSocketToServiceRecord(uuids[0].getUuid());
socket.connect();
outputStream = socket.getOutputStream();
inStream = socket.getInputStream();
}
Log.e("erro", "Dispositivos não estão conectados.");
}else{
Log.e("error", "Bluetooth está desligado.");
}
}
}
public void write(String s) throws IOException {
outputStream.write(s.getBytes());
}
public void run() {
final int BUFFER_SIZE = 1024;
byte[] buffer = new byte[BUFFER_SIZE];
int bytes = 0;
int b = BUFFER_SIZE;
while (true) {
try {
bytes = inStream.read(buffer, bytes, BUFFER_SIZE - bytes);
} catch (IOException e) {
e.printStackTrace();
}
}
}
