Hello,
I am trying to add HackRF support to Salvatore Sanfilippo's dump1090
tool (https://github.com/antirez/dump1090) as a learning exercise. The
tool was originally designed for RTL SDR devices. However, I can't seem
to get this port to work.
To eliminate potential issues in my code, I simplified the
troubleshooting steps. Here are the basic set of troubleshooting steps I
am using:
Per tool's documentation, a data file can be captured with rtl_sdr
utility in the following way:
rtl_sdr -f 1090000000 -s 2000000 -g 50 output.bin
Then you can pipe it into dump1090 like this:
dump1090 --ifile output.bin
I made an assumption that the HackRF equivalent of rtl_sdr command above
would be the following:
hackrf_transfer -r output.bin -f 1090000000 -s 2000000 -p 0 -a
0 -l 40 -g 62
However, capturing packets with HackRF this way and piping them into
dump1090 doesn't do anything. I have tried this sitting next to an
airport and capturing packets while planes were landing and taking off.
I don't have an RTL SDR dongle so I can't test the rtl_sdr command
myself. It didn't make to sense to buy a RTL SDR device after HackRF but
if I can't crack this, I am considering to buy one.
BTW, I also tried different gain settings, and sample rate of 8e6 with
hackrf_transfer, no difference. That said, I never enabled amp_enable.
Would anyone know if rtl_sdr and hackrf_transfer capture the packets in
the same way and format? Or do I need to do some kind of a conversion or
translation in between the two to make them compatible?
Any help or idea will be appreciated.
P.S. I am aware of gr-air-modes for HackRF to decode ADS-B signals. My
goal is to hack dump1090 and add HackRF support as a learning exercise.
Thanks,
Ilker
