title: Game Command format between bluetooth controller and console
body: <p>I am creating an Android project, in which I have to make <code>android wearable</code> smart watch as game controller which can send commands to games running on handheld device connected to that smartwatch over <code>BLE(Bluetooth Low Energy)</code>.</p>
  
  <p>I designed controller pad on wearable and can send some hard coded text to handheld device app on soft button click of controller pad. Issue is, I have to replace that text with game commands format expected by games running on handheld device. And, the app running on handheld device can listen text through wearable service. I know that, third party games would not have any wearable service running, so how third party games will accept/listen command sending from wearable smartwatch.</p>
