您可以連接的設備讀取RSSI（信號強度）。

獲取Extra EXTRA_RSSI從ACTION_FOUND意圖獲取RSSI。

private final BroadcastReceiver receiver = new BroadcastReceiver(){ 
    @Override 
    public void onReceive(Context context, Intent intent) { 

     String action = intent.getAction(); 
     if(BluetoothDevice.ACTION_FOUND.equals(action)) { 
      int rssi = intent.getShortExtra(BluetoothDevice.EXTRA_RSSI,Short.MIN_VALUE); 
      Toast.makeText(getApplicationContext()," RSSI: " + rssi + "dBm", Toast.LENGTH_SHORT).show(); 
     } 
    } 
};
