title: How to have multiple connections to a single Obd2 bluetooth device connected to car
body: <p>I have to do an  Android application that reads value via Bluetooth from a Bluetooth device connected to OBD-II port of a car.</p>
  
  <p>I use the UUID SPP UUID 00001101-0000-1000-8000-00805F9B34FB .</p>
  
  <p>If I create 4 threads that want to connect to the OBD-II device, 3 <code>connect()</code>s fail and only one thread is able to connect to the device.</p>
  
  <p>Is there a way to connect more thread to an OBD-II device via Bluetooth?</p>
  
  <p>I don't know if the <code>elm-237</code> device is able to communicate with more threads.</p>
