[Discuss-gnuradio] GRC 3.7.11 on Windows crashes python.exe

[Gavin Jacobs]

I have a hackrf-one working fine on Windows 10 with GRC 3.7.11, so it should be possible.

Here are some things to try:

1) Open a windows command prompt, navigate to C:\Program Files\GNURadio-3.7\bin

then run hackrf_info . You should see some information about your hackrf (serial # etc.)

2) In the same place, run this command (but change YOURNAME to your actual username)

hackrf_transfer -f 100700000 -s 10000000 -r C:\Users\YOURNAME\Documents\test

Wait a few seconds and then type CTRL-C. If the hackrf is working, you will see something like this:

call hackrf_sample_rate_set(10000000 Hz/10.000 MHz)
call hackrf_baseband_filter_bandwidth_set(9000000 Hz/9.000 MHz)
call hackrf_set_freq(100700000 Hz/100.700 MHz)
Stop with Ctrl-C
19.9 MiB / 1.002 sec = 19.9 MiB/second
19.9 MiB / 1.001 sec = 19.9 MiB/second
20.2 MiB / 1.000 sec = 20.2 MiB/second
Caught signal 0
19.9 MiB / 1.001 sec = 19.9 MiB/second

User cancel, exiting...
Total time: 4.00359 s
hackrf_stop_rx() done
hackrf_close() done
hackrf_exit() done
fclose(fd) done
exit

3. If the above works, try running GQRX. If the Hackrf is the only radio on your system, it should pick it up automatically and you should be able to receive a wideband FM radio station in your area.

4. If you think the problem is in the hackrf , you can also try the hackrf mailing list

Good luck,

Trying to use a HackRF One with GNU Radio on Windows 10 (64-bits), installed from gnuradio_3.7.11_win64.msi.
When using osmocom Source and executing the flow graph, execution halts with message: python.exe has stopped working. GRC remains alive.
Crashes happen both with WX and QT. The HackRF One module is put into Receive mode (Rx Led of HackRF One is on).

GNU Radio, GRC, Hack RF and computer do work as expected with the GNURadioLiveDVD<https://wiki.gnuradio.org/index.php/GNURadioLiveDVD>.
