Thanks Derek and Martin. I followed the instructions regarding permission access to USB. I’m not positive but I think I had to rerun setup_env.sh as well. Now uhd_find_devices functions as expected. Thanks you. I ran the uhd_wbfm_receive flow graph. At first I did not get any audio. I don’t know why but looking in my sound settings, the audio was going to Digital Output rather than Headphones output (never did that before). You will see at the bottom of the transcript below that there are UHD warnings and an “Environment Error” but it is not clear to me if I need to address them. I will do more homework. One more question however, should I run volk_profile or did the pybombs install already take care of that? One more comment, it seemed previously I could just type the python script names our click on a script in my file manager. Now I need to precede the scripts with ./ and clicking on scripts in the file manager no longer executes them. Again I will do more homework on my own. Thanks again for all your help.

I then ran setup_env.sh. However now I cannot seem to connect to the B100. I ran uhd_find_devices and followed the instructions to download images as per the transcript that follows. Was PyBombs supposed to take care of downloading the images? If not, it seems the pybombs instructions should tell one to do so. In any event per the following transcript it now appears I have a permission issue to access my USB ports. Any advice as to what to do next?

You still have an old UHD installed. Remove that and start from scratch. M _______________________________________________ Discuss-gnuradio mailing list
