micro BladeRF ADSB
Posted: Wed Nov 21, 2018 12:44 am
Hi,
I recently purchased the BladeRF micro XA4. I was able to install GNURadio and create an FM tuner to receive stations with the BladeRF micro.
I tried to follow the instructions for the BladeRF-adsb project but ran into several issues.
- Build failure.
After modifying the makefile and modifying the API’s to version 2.0. I am able to build and run the bladeRF-adsb app.
- The adsbxA4.rbf FPGA file produces no output.
However, if I use the hostedxA4-latest.rbf FPGA bitfile (which I believe is now supporting adsb) I do get what seems visually valid raw output spewing out of the bladeRF-adsb app. However, the dump1090 app rejects most of the data as invalid (crc errors).
This is as far as I could go in my attempt to get adsb working on the BladeRF XA4.I would like to know:
- When will the bladeRF adsb GitHub site will be updated to support the new micro devices?
(It seems that there some TODOs, e.g. update of the Makefile, from 2016)
- Does adsb need some sort of an RX LNA like the BT200?
I have an ANT500 (75Mhz - 1GHz) antenna attached which should be quite capable or receiving adsb data, but I am getting nearly all CRC errors in the raw data.
Thanks.
