[Hackrf-dev] Gqrx can't find hackRF

[Jay Hamlin]

Its working!  this is fantastic.  Brian, you were right.  the command to install hackrf must come before installing osmosdr

Thanks everyone!

Jay.

Use "brew uninstall" against both hackrf and gr-osmosdr, then run them again with hackrf first and gr-osmosdr second, so that the osmosdr configure/make detects libhackrf and uses it. You should be off and running after that.

I used hackrf_spiflash and hackrf_cpldjtag to update the firmware and hackrf_info reports good information like everything is fine. But hackRF does not show up as a device in Gqrx and osmocom_fft reports no device found.  I saw one other report like this in the archives but with no resolution.  It seems like there must be a simple configuration or path wrong but I can’t figure it out.  Please help.  Thanks.  Jay.
