title: HM-10 BLE module automatic reconnect
body: <p>I have an HM-10 BLE (v549 firmware) module with a PIN set. I want my phone to connect to it automatically. Is this possible with BLE modules?  </p>
  
  <p>The first time it is discovered, I click on it and, after entering the PIN, they are connected (as indicated by the LED that stopped blinking). Then if I turn off either the module or my phone's bluetooth and I turn them on again, nothing happens. The phone does not connect to the module, even if I click on it. I have to unpair from my device and repeat the process for a connection to be established.</p>
  
  <p>How can I setup the HM-10 so that my phone will automatically connect to it whenever it is within range?</p>
  
  <p>Thank you.</p>
