Hi Dave,

Thanks for the information,very helpful 🙂 I haven’t looked at this topic for a while, so I’m not surprised it’s been fixed.

W8ism,just thought I’d tell you ,I googled NanoVNA-Saver release,on web page I selected top search option which took me to a github page ,scroll down page to latest releases you will see latest raspberry pi version approx 107mb ,download file to wherever you use,it’s an execute file I had to change my execute permissions,right click exe file then properties and allow yourself to open exe files ,then double left click on file ,after a wee while NanoVNA WILL SHOW ON SCREEN,mine works a treat on my Raspberry Pi 400,totally stoked I am,and no Terminal code to deal with ,Dave 2E0DTB 73 take a look Mike G4WNC

Instead just download and unzip/extract the 5.5 version:
https://github.com/NanoVNA-Saver/nanovna-saver/archive/refs/tags/v0.5.5.zip
or
https://github.com/NanoVNA-Saver/nanovna-saver/archive/refs/tags/v0.5.5.tar.gz

Works like a champ on a pi5! The initial screen may come up larger than the display, so just use Alt-(mouse-left-click), or sometimes FN(WindowsKey)-(mouse-left-click) which allows you to drag the image so it can be resized from the corner.

Hi Russ,

Unfortunately, the latest version of NanoVNA Saver requires PyQt6, which is not currently available or easy to install on the Raspberry Pi. When this situation changes I’ll update the instructions.

Regards,

Mike

rcnixon@raspberrypi:~/nanovna-saver $ python3 nanovna-saver.py

During handling of the above exception, another exception occurred:

Do you have any enlightenment for me?

Thanks.

Hi Tim,

It’s usually automatic because Linux loads the appropriate driver as soon as a new hardware connection is detected.

You can check to see if your NanoVNA is being detected as follows.
With your NanoVNA disconnected, open a terminal session and enter ls /dev/ttyAMA*
This will list any connected serial ports
Next, plug in the NanoVNA and run the command again. The NanoVNA will normally appear as /dev/ttyAMA0

Hi Bob,

Glad to hear that you’ve got it going. Also very pleased to hear that you’ve found my book useful. I was trying to make it a practical rather then a theoretical resource.

Hi Bob,

I’ve just used the instructions to install NanoVNA Saver (0.5.4) on a fresh copy of 64-bit Bullseye and it’s working fine with my NanoVNA-H4 and NanoVNA V2 plus

Mike
