title: Gatt server device name length in Android
body: <p>I'm making an Gatt server app runs on android device and it works well.</p>
  
  <p>But I have a question about device name.</p>
  
  <p>I created this application with my "Nexus 5X", and it's default device name is "Nexus 5x" and Gatt client can scan this device well.</p>
  
  <p>However, if server ran on "Galaxy S7", client can't find the server device.</p>
  
  <p>So, I checked server's device name, it was "Samsung Galaxy S7" in default. After change the name to "gal7", it worked fine.</p>
  
  <p>In my test, the android gatt server allow device name length maximum 8characters.</p>
  
  <p>"Nexus 5x" --> fine</p>
  
  <p>"Galaxy S7" --> bad</p>
  
  <p>"Nexus" --> fine</p>
  
  <p>"long name device" --> bad</p>
  
  <p>Is there any reason(bug or not), gatt server device name length limitation?</p>
