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

I’m running “buster” on a Pi 3b+ and I’ve installed NanoVNA Saver per your instructions. When I run it from the command line, I get this output:

rcnixon@raspberrypi:~/nanovna-saver $ python3 nanovna-saver.py
Traceback (most recent call last):
File “/home/rcnixon/nanovna-saver/nanovna-saver.py”, line 28, in
from NanoVNASaver.__main__ import main
ModuleNotFoundError: No module named ‘NanoVNASaver’

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File “/home/rcnixon/nanovna-saver/nanovna-saver.py”, line 33, in
from NanoVNASaver.__main__ import main
File “src/NanoVNASaver/__main__.py”, line 31, in
from PyQt6 import QtWidgets
ModuleNotFoundError: No module named ‘PyQt6’
rcnixon@raspberrypi:~/nanovna-saver $

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 Mike –
Thank you so much for this posting. I can get the software to work from the command line but not the desktop. That’s ok I’ll figure it out. But what is the trick in getting the NanoVNA to shake hands with the pi?

Best .

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 Mike,
Many thanks for checking the instructions. I reloaded and now nanoVNS-Saver works OK on the Pi, although I note that there were changes made yesterday to NanoVNA-Saver software and I am not doing anything different from the day before!
Thanks again.
PS Your book “NanoVNAs Explained’ is exellent and very useful to any nanoVNA user.

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

Regards,

Mike

Hi Mike,
Can you confirm that the above instructions still work with the latest NanoVNA-Saver release 0.5.4? I find that the programme runs but aborts on connection to the NanoVNA. (AttributeError: module ‘scipy’ has no attribute ‘signal’ – Aborted). Using Pi4 with OS Bullseye 64 bit.
Regards
Bob

Hi Derek,

It’s probably a typo. However, there is an alternative way to assign an icon to a desktop link.
1. Right-click on the desktop link
2. Select Properties
3. Click on the icon image – this will open a panel where you can choose your desired icon.
4. Once you have your selected icon hit OK to exit the panel and you’re done.

Let me know how you get on.

Installed per instructions. Program works from the command line (even got it to recognize my nano vna) but I cannot get the desktop icon directions to work? I am new at this so please bear with. In the command lines for the desktop icon do I need to change anything for my specific device, ie; instead of just “pi”? Using a new Pi4 with Raspbian. Any help is appreciated.
