How to Integrate an External Device with the NoviSign Android App

This guide explains how to connect an external device (such as a sensor, RFID reader, or any system that can send data) to the NoviSign Android player.

Once connected, your device can trigger content on the screen automatically—for example, displaying specific content when a sensor detects an action.

The NoviSign Android app continuously checks your external device for events:

• Every 0.5 seconds (500ms), the app sends a request to your device (server)
• If an event is detected, the device responds with a simple XML message
• The app receives this event and triggers the relevant content (creative) in your playlist

Before you begin, make sure:

• The Android device with the NoviSign app and the external device are on the same network (Wi-Fi or Ethernet)
• Your external device can respond to HTTP requests
• You have access to your NoviSign Studio account

1. Open the NoviSign app
2. Click the gear icon (top-right corner) to open settings
3. Scroll down to External Interfaces
4. Select Custom Event Transmitter
5. Enable it
6. Enter:
   • IP address of your external device
   • Port number (e.g. http://10.0.0.17:1212)

Your external device should respond to this endpoint:

Example XML response:

Supported event examples:

• General:event1
• General:event2
• General:event3

1. Create a playlist
2. Add your creatives (content)
3. For each creative:
   • Click the schedule icon (date/time picker)
   • Assign it to play only when a specific event is triggered

Let’s say you have a tablet with the NoviSign app and a connected sensor:

1. The app checks the sensor every 0.5 seconds
2. The sensor detects an action (e.g. RFID scan)

3. It returns:

   <event code=“General:event1” />
4. The app receives the event
5. A specific creative (assigned to event1) is displayed on screen

To integrate an external device:

• Configure Custom Event Transmitter in the Android app
• Set up your device to return XML events via HTTP
• Assign events to creatives in your playlist

Once set up, your content will automatically respond to real-world triggers.
