title: How to run GATT command in Android
body: <p>I'm developing an Android application for read/write data for a BLE device. The specification of the device has mentioned one service UUID and two feature UUIDs. 
  <code>Service UUID: 0xFFF0</code>
  <code>TX UUID: 0xFFF6</code>, <code>RX UUID: 0xFFF7</code></p>
  
  <p>And bunch of command formats as follows.</p>
  
  <p>For example, for Get time:</p>
  
  <p><code>Command format: 0x41 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 CRC</code></p>
  
  <p>When running a <code>serviceDiscovery()</code> there are some additional UUIDs are appeared. But there's no use of them.</p>
  
  <p>Is there any special way to run commands like this in Android?</p>
  
  <p>I'm quite new to Android development. So, can someone help me to overcome this situation? </p>
