Can't get the bladeRF to show up in gqrx. Suggestions?

Post by jsn »


I'm having an issue getting my bladeRF to show up in the gqrx devices drop down. I took the following actions...

1. Ensured that the FPGA is loaded with firmware
2. Installed all prerequisite software
3. Purged the gqrx configuration file under ~/.config
4. Ensured the device was plugged into a USB 3.0 port
5. My bladeRF shows multiple green lights lit (three in a row, a space, then a fourth light)

Here are my outputs. Any thoughts on the configurations?

Linux host system:

However, if I even attempt to test using gr-osmosdr derived utilities, such as osmocom_fft, I get the following output...

FATAL: No supported devices found to pick from.

Trying to fill up 1 missing channel(s) with null source(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.

Source has no sample rates (wrong device arguments?).

What am I missing here? Thank you all in advance for your assistance!
