Add missing io import

[NebraskaCoder]

Receiving an error in rx.py that io is not defined. Importing it in rx.py fixed the error.

[boatbod]

Fixed, thanks!

@NebraskaCoder Seems like you’re also checking out the same setup as me. Can you try to run your install with the web server flag? It wouldn’t work for me and had some errors. Just curious if you see the same thing (I also had the io issue this morning and manually fixed it).

@alphafox02 Are you getting the error osmosdr source_c creation failure?

Error in stderr is:

gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.8.1.0

  File "./rx.py", line 145, in __init__
    gain_names = self.src.get_gain_names()

Usually this happens when op25 / gr-osmosdr cannot find the rtl device.
Does it show up in the "lsusb" command?

[NebraskaCoder]

Disregard. My error is now this:

Like Boatmod said, I get the error you first showed when no device is plugged in. I’ll have to check the second error - it’s only when I try to access the web server do I see it in the terminal and nothing loads in the browser. If I run rx.py just in terminal without the web server option it seems okay, but I’m new and still figuring it out. Might take me awhile to report back.

[boatbod]

The waitress error is reproducible and relates to python3 binary vs string. Unfortunately I haven't tracked down exactly what's causing it yet.

[NebraskaCoder]

@alphafox02 your error should be easy to fix as it is the dongle as @boatbod said. My new error is something boatbod will have to look at as it is different.

[alphafox02]

Yes, no issues with an rtlsdr plugged in. Running the web server option is where I see the same error as you. I’ll check back for updates.

[boatbod]

Please pull the update and try it again.

[NebraskaCoder]

Looks good! Thanks!
