Failed to use '0' as HackRF device index: not enough devices #21

Closed thenerdie closed 2 years ago

Hey!

I'm trying to transmit with my HackRF, and I keep running into issues. I cloned the repo, ran the batch of commands that were outlined in the README, and tried to run it with GNU Radio Companion. Yesterday I got the error Failed to open HackRF device (-1000) Access denied (insufficient permissions), so I tried tinkering for a few hours to no avail. I even tried this thing and refreshed the rules with udevadm control --reload-rules (just tried it with udevadm trigger, still no luck). Today I keep getting the error Failed to use '0' as HackRF device index: not enough devices both in GNU Radio Companion and by manually executing the Python code with python hd_tx_hackrf.py.

I'm running Manjaro version 21.1.4, and GNU Radio version 3.9.2.

It sounds to me like something is wrong with your udev setup. I'd suggest following the instructions here: https://hackrf.readthedocs.io/en/latest/faq.html

Since this is not a problem with gr-nrsc5 itself, I'll close off this issue for now.
