Hi!
I need your help.
I received this output. What's mean this results? How I could get drone_id data from this results?

If you Google gr-droneid YouTube you should find three videos that’ll walk through taking the capture from the air into decoded format. Hope that helps.
@alphafox02 Unfortunately I have seen this video but it didn't help. In this video version of dii_droneid library is so old. Output is different. I'm not sure but as I can see in latest version library gr-droneid could decode frame in realtime.
Please, tell me how could it have to work?
The same steps can apply. I tested it. With gr-drone for gr10 there’s still bursts saved to /tmp along with what you’re seeing in the bottom left corner of gnuradio. I take those bursts and combine them into one and run through octave and get the frames. I then run through python script for results.
I would have to check the real time output vs the info I get from the bursts in temp, but I can say the basic process shown in the few videos works in latest DragonOS (has the newer dji droneid and gr-droneid). Check and see if you’re getting bursts in /tmp and then use those with octave to verify against the live output from gnuradio.
@alphafox02 I have some different files in /tmp. There are burst_* burst_post_coarse_cfo_correction_* cfo_estimate_cyclic_prefix_* cfo_estimate_end_of_symbol_* expected_zc_* received_zc_*
What's files I have to take from /tmp? It will be burst_* ? And how can I combine them? What tool you use for this?
Sorry for my stupid questions) I'm really want to understand it)
Not dumb at all. Instead of running each burst one by way through the octave script which I have to edit manually, I instead took the burst_* files and then (I’m having a memory lapse) I think just like this is fine..
cat file1 file2 > file3
but do all the burst files. Someone correct me if I’m wrong, then I configure the script file per the video pointing it at the one large file I just made. At the end, if all goes well, it should say found FRAME xxx zzz and have lots info. I then copy and paste the info into a text file per number 3 of 3 videos on YouTube and use the python script inside DragonOS to get the decoded results.
@alphafox02 Thank's for your answer it helped me. I have just understood what's my problem. I have Mavic Air 2S and I'm using it for my tests. But I'm not sure that it has Ocusync 2 protocol. What can you tell about this?
And one more question. What about Mavic 3? Can I get drone_id using these tools from Mavic 3?
