title: Multiple BLE devic connection using gatttool
body: <p>To monitor multiple BLE devices and record the incoming data.</p>
  
  <p>In order to achieve this I should be able to connect to multiple ble devices. Right now I can open one interactive mode using gatttool and connect to the ble device (On raspberry pi). If I want to connect to one more ble device I have to open a new terminal window. </p>
  
  <p>Can anyone help me on how to connect to multiple ble devices keeping the target in mind.</p>
