How to receive Status or Single Frame Data from HTTP Block?

Postby Moderator » Friday 9. June 2017, 14:09

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):

Code: Select all
{
   "data": {
       "tracks": [
           {
               "altitude": -1.0462738275527954,
               "bearing": 2.7427170276641846,
               "detectTime": 1494231786.0274136,
               "energy": -38.492889404296875,
               "info": "Frame\tQuadcopter\nDiameter\t590mm\nVeloctiy\t20m/s\nRange\t3500m\nStamina\t28Min\nWeight\t1,38kg\nPayload\t0,462kg\n",
               "name": "DJI Phantom 4",
               "probability": 1
           },
           {
               "altitude": -1.0233732461929321,
               "bearing": 2.8442740440368652,
               "detectTime": 1494231787.0813968,
               "energy": -49.153297424316406,
               "info": "Type\tRemote Control\nFrame\tCopter\nChannels\t36 Channels\nBandwidth\t2048kHz\nModulation\tGFSK (FASST)\n",
               "name": "Generic 2.4GHz RC",
               "probability": 0.9977357387542725
           }
       ]
   },
   "endTime": 1494231793.6948342,
   "startTime": 1494231793.6948342
}
