How to setup Nexmosphere's XT-B4 push buttons

In this example We use a Nexmosphere XN-185, XT-B4, and Push buttons.

Please note, in order to use Sensors and Sensor events, Premium (ENTERPRISE) license is required.

Setup & Configuration​

  • Attach the sensors to the device where you want to use them.
  • Navigate to Devices menu, then select the device where you want to use the sensors.
  • Open the device settings by clicking on the icon

OR

  • Click on the device card, then Select Settings tab
  • Find sensor settings, then set the following sensor configuration:
{
  "services": [
    {
      "uid": "NEXMO",
      "type": "GENERIC",
      "connection": {
        "baudrate": 115200,
        "port": "2"
      },
      "settings": {
        "rules": [
          {
            "pattern": "(\\w\\d{3}\\w)\\[(\\d*)]\r\n",
            "eventGroupIndex": 1,
            "valueGroupIndex": 2
          },
          {
            "pattern": "(\\w\\d{3}\\w)\\[(TR|TD)=UID:([A-Za-z0-9]*)]\r\n",
            "idGroupIndex": 1,
            "eventGroupIndex": 2,
            "valueGroupIndex": 3
          },
          {
            "pattern": "(\\w\\d{3}\\w)\\[(\\w*)=([A-Za-z0-9]*)]\r\n",
            "idGroupIndex": 1,
            "eventGroupIndex": 2,
            "valueGroupIndex": 3
          }
        ]
      }
    }
  ]
}

  • The pattern regexp determines the format of received messages.

  • Attach the buttons to the Nexmosphere XT-B4 interface.

  • Attach the Nexmosphere XN-185 controller to the Android device.

  • Open a console on the Android device from the Wallboard CMS and check if the events appear after pressing the button

Create content​

  • The main concept will be the buttons switch pages, and an image widget sends back message to the Nexmosphere controller

  • First we set up the received message handling under the Content properties Edit sensor events section

Received values​

Received message: { " event " : " X001A " , " value " : " 3 " }

Received message: { " event " : " X001A " , " value " : " 5 " }

  • Now set up the event sending on the image widget. When the widget is interacted it will send the value to the Nexmosphere controller.

Turn on "button 3" light​

Turn off all button lights​

Now everything is set up. Assign the content to the screen and try out the concept by pressing the buttons and the images
