App Downlink

The app downlink section controls what the user sees on the device screen. You can send new widget values, trigger UI actions, and manage message lists.

Commands target a named Device View (DV) and can include both data and actions in the same message.

  "app": {
    "<dvname>": {

      },
      "actions": [
        { "a": "<action>", "p": "<param>" }
      ]
    }
  }
}
