8.9.3. Registering scan start and callback
To start the Beacon function, register the callback function using setGapCallback() to receive
Advertise from the Beacon device, and start scanning using startScan().
import android.widget.Toast;
public class MainActivity extends Activity {
private BluetoothLeAdapterManager mManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
//Instance acquisition for the BLE manager class
mManager = BluetoothLeAdapterManager.getInstance();
//Register a callback for the GAP function provided
mManager.setGapCallback(mLeGapCallback);
}
private void scanLe(final boolean enable) {
if ( enable ) {
//Start scanning
mManager.starScan();
} else {
//Stop scanning
mManager.stopScan();
}
}
Receive scan results using the following callback, and output the received signal strength to a
log.
private BluetoothLeGapCallback mLeGapCallback = new BluetoothLeGapCallback(){
@Override
public void onScanResult(AddrType addrType, String addr, int rssi
, byte[] adv_data) {
Log.i(“DEBUG”, “rssi=” + rssi);
}
};
}
