Some problem about dji_droneid HOT 1 OPEN

I'm not sure I quite follow the question. It sounds like you recorded samples with the file sink in GNU Radio and then processed those samples with the process_file.m script. It's quite likely that there are no bursts in the file you recorded. DroneID doesn't appear very often (~ once every 600 milliseconds) and frequency hops which doesn't give you much of a chance of actually recording a burst. If you saved off the exact same samples that you saw burst detections for in GNU Radio then it should work. If you post a screenshot of the recorded file in Baudline then I might be able to tell you if what you have likely contains DroneID bursts that for some reason were not processed properly.

Also, what SDR did you use to collect the samples?
