I am using the HTTP blocks for remote control. This works great!
I know that somehow it is possible to get a singe "snapshot" of the datas coming from the HTTP block via my web browser (instead of a steady stream). How can i do that?
I would like to get those information from the drone detector block so i can allign my camera to the drone.

All you have to do is to add the port number to the browser and then add "sample". You will then get a data "snip" from the stream e.g. " http://localhost:54664/sample".

The JSON dataoutput from the "Drone Detector" block would then look something like attached sample (detection of one drone and one remote):

   "data": {
       "tracks": [
