bladerf_sync_rx error: Operation timed out

[arBalasquide]

Hello,

I'm following this GNURadio tutorial for making a spectrum analyzer. I'm using osmosdr block to use my bladerf as a source, I'm also using gnuradio 3.9.2. My bladeRF sdr is this one.

However, when I run the flowgraph I get the following error:

I downloaded the latest FPGA and flashed it to the device with no errors.

I've uploaded the grc flowgraph I made here if someone can spot any obvious errors.

I'm new to this so I'm not sure what might be causing this issue. Perhaps a hardware issue? I have it connected to a 3.0 USB port, although not entirely sure if the cable I'm using supports 3.0.

It appears there might be a version/compatibility mismatch. To upgrade the bladeRF's firmware, please take a look at: https://www.nuand.com/fx3_images/ and update the bladeRF using bladeRF-cli -f .

If you're using GR 3.9, please give gr-bladeRF a look. https://github.com/Nuand/gr-bladeRF/

The time out seems to be fixed now by updating the firmware. Thank you!

I tried using gr-bladeRF blocks but I get a module not found error every time.

I've already opened an issue a few days ago here

Everything works now, the module error was an issue with my python path. Thanks for the help!
