Text display works, icon is not displayed. Is the JSON correct?

Hello everyone,

what exactly does the JSON need to look like for the icon and text to be displayed on the Pixelit (Ulanzi)?
The following (sent to an MQTT Output Node) only displays the text, but not the icon.

{ "text": { "textString": "Test", "hexColor": "#00FF00", "position": { "x": 8, "y": 1 } }, "icon": { "id": 1908 } }

IDs only work with NodeRed. The PixelIt Core node downloads the bitmap. When using a native json you need to send the raw image like described in the documentation. The device will never download the image - thats by design :)

Thanks for the quick reply and the tip. I'm using Pixelit with Nodered (node-red-contrib-pixelit). I'm wondering why it's not working.

Now I'm trying to figure out how to adjust the native JSON so that an icon with text next to it is displayed.

The text is displayed:

{
  "text": {
    "textString": "Test Test",
    "bigFont": false,
    "scrollText": "auto",
    "centerText": false,
    "position": {
      "x": 8,
      "y": 1
    },
    "color": {
      "r": 255,
      "g": 255,
      "b": 255
    },
    "hexColor": "#ff0000"
  }

}

The icon is displayed:

{
  "bitmap": {
    "data": [0,0,63650,63650,63650,63650,0,0,0,0,63650,63650,63650,63488,63488,0,0,0,65139,25388,65139,25388,0,0,0,0,65139,65139,39296,39296,0,0,65139,63488,12918,63488,63488,12918,63488,65139,0,0,12918,12918,12918,12918,0,0,0,0,12918,12918,12918,12918,0,0,0,0,39296,0,0,39296,0,0],
    "position": {
      "x": 0,
      "y": 0
    },
    "size": {
      "width": 8,
      "height": 8
    }
  }
 }

Unfortunately, when the two parts are combined, nothing is displayed on the Pixelit. What am I overlooking?

{
  "text": {
    "textString": "Test Test",
    "bigFont": false,
    "scrollText": "auto",
    "centerText": false,
    "position": {
      "x": 8,
      "y": 1
    },
    "color": {
      "r": 255,
      "g": 255,
      "b": 255
    },
    "hexColor": "#ff0000"
  },
  {
  "bitmap": {
    "data": [0,0,63650,63650,63650,63650,0,0,0,0,63650,63650,63650,63488,63488,0,0,0,65139,25388,65139,25388,0,0,0,0,65139,65139,39296,39296,0,0,65139,63488,12918,63488,63488,12918,63488,65139,0,0,12918,12918,12918,12918,0,0,0,0,12918,12918,12918,12918,0,0,0,0,39296,0,0,39296,0,0],
    "position": {
      "x": 0,
      "y": 0
    },
    "size": {
      "width": 8,
      "height": 8
    }
  }
 }
}

Can you make a screenshot of you flow? When you use Node-REd, the core-node handels the icon download and the playlist data caching etc..
