Running NanoVNA-App on Raspberry Pi

 

Please note this is about NanoVNA-App NOT NanoVNA-Saver!

I've got it to run successfully on a Pi4 with the Twister OS (if anyone's interested I'll tell you how) but it has a couple of issues which limit its usefulness.

The trace is noisy and the amplitude scale reads 0.0001dB low (see attachment).

Unless anyone has any idea how to fix this I'll reluctantly have to revert to using Windows.

Re: RF Demo Kit for NanoVNA H4? #nanovna-h4

 

it will work with any item that uses sma connectors.
It is a basic educational tool - good fun to learn with.
The durability of the connectors is time - limited , but you should have got bored with it before they give up.
Practical use - well you could use it for S.O.L.T , but swapping those connectors might get onerous.!
Just get one - play, learn, & have fun..

RF Demo Kit for NanoVNA H4? #nanovna-h4

 

I see RE Demo Kit for NanoVNA-F for demonstration. Would it also work for the H4?
Is this a good kit for NanoVNA beginners for learning?
Does it have any practical use than educational?

I also read a lot of complaints about the kit.
How do you find it yourself?
Re: Running NanoVNA-Saver on Windows 7

 

Here is a link to a post I made earlier with download links for WIN 7 drivers and a version of NanoVNA Saver which runs on WIN 7.

Re: Android NanoVNA app

 

Chris,
I can't help you any more with the NanoVNA App running under Android.
But if you are interested in the topic, you can use the 32-bit version of the NanoVNA-App running under Windows on Linux OS with Wine.
You can run it on a Raspberry Pi (4B), which is where I tried.
You need to install Twister OS v2.1.2 on the microSD card.
The files required to run the OS and Wine are already installed on it.
First you need to start Wine Config, then it will install two programs.
When finished, select the OS you want to emulate in the Config window. By default, Windows 7.
Then copy NanoVNA-App-1.1.211.exe into the Documentation folder.
After starting Wine, select it in the file manager window and run it.
You can see how the program will log in on the attached link.:
Use the NanoVNA with the latest firmware, the NanoVNA-App is updated for this. (v1.2.x)

Correction - normally an udev rule is not required for operation via the USB serial port - it is sufficient to be in the group "dialout" - should be the case for Ubuntu, you can check with the command "groups".

But nevertheless this udev rule above can be helpful, because it creates a symlink "/dev/nanovna" that points to the USB serial port where the NanoVNA is connected, regardless of the port name (either ttyACM0 or ttyACM1,...), and "/dev/tinysa" for the tinySA. If you have both devices connected to your system, these links are always correct, no need to check where the nano and the tiny are connected.

Why do you try the "exe" on a Linux system? - just follow my advice from below - open a terminal, go to a project or development directory and do this (maybe you need to install git: "sudo apt install git").

git clone

Then enter the directory:
cd nanovna-saver

and just type
python nanovna-saver.py

Check the error messages (missing modules) and install them, e.g. these are essential:
sudo apt install python3-numpy python3-scipy

until the program starts without complaint.

To follow the development, just fetch an update with
git pull

If you want to install the tool in your path, you can create a Debian package by typing
make deb
For this you need to install python3-stdeb, the module for converting Python code and modules to a Debian package.
sudo apt install python3-stdeb

You need also an udev rule that allows user access to the USB serial port of NanoVNA and tinySA.
This is currently not part of the package - just use this one and install it into /etc/udev/rules.d:

Re: Nanovna Saver stopped working

 

Hi,

I guess its wine that has stopped working after the upgrade. Can you run
any other Windows (exe) programs on your computer? (Something like LTSpice)
Check the software center if wine is installed. If it is, and you are not
able to run any windows programs, you need to search for help on fixing
wine.

Or, you could run the python version of nanovna saver instead. Instructions
should be in the repository.


Regards,
Askild

Re: "Bricked" after attempt to update FW #nanovna-v2 #firmware #crash #newbie #flashing

 

You most likely had a weird chip and firmware combo too. Take it as a
learning experience.

- know your hardware
- make backups of firmware (ideally 2x & crc)
- check if updates are compatible with your device, only flash if you¡¯re
100%sure.
- learn jtag level reflashing for the device.

As for the GD, glad my tip helped point things in the right way.

This gave me an idea.

Does the reverse apply? If the manufacturer used STMCube, could I have
successfully loaded an old NanoVNA dfu with DfuSE-Demo which ran with
anomalies but then when I tried to load a different version the computer
would not recognize the device being plugged in when booted with jogwheel
pressed?

You're right, I destroyed the bootloader so I cannot use either
NanoVNA-App or QTbut I already verified that I can communicate to the MCU
via STLinkso I'll go ahead and flash it keeping my fingers crossed....I'll
return with good news of success.

Yes.
Re: "Bricked" after attempt to update FW #nanovna-v2 #firmware #crash #newbie #flashing

 

that is still an older fw .. but at least you have a working unit with a working bootloader (so your pc should find it)

dislord sure has a newer fw for it ... 17th (19th) of june 2020 is VERY old! (why 17th (and 19th in brackets)?? see version NUMBER .. there you fint the 17 ... and below that when it was compiled (2 days later it seems) ...but .. it is from 2020!! and i surely know that we have many many new versions since that year

... DISLORD?? what is newest he can throw on his unit?? 1.309?? or even newer like the 1.312??

(he sure can better answer what fw is newest from his workbench) ... that one he sent is not new but it works (to realive your unit)

and soon he wil tell you what is newest fw that matches (i bet he has a 1.312 or so if not newer)

Re: NanoVNA H4 OSL calibration question (newbie) #calibration #nanovna-h4

 

There is one particular use case where no calibration is needed at all, and that is when tuning a magnetic loop or similar antenna, where the only adjustment is resonant frequency. The S11 VSWR/log mag dip will be at the same frequency regardless of calibration status.

Depending on your firmware version, you can save multiple sets of
calibration data.

I saved all five sets in my nano, specifically, 3 Mhz to 15 Mhz, 15 Mhz
to 30 Mhz, 3 Mhz to 30 Mhz, 143 Mhz to 149 Mhz, and 420 Mhz to 450 Mhz,?
I then load the calibration data as needed for the antenna span being
checked.

Yeah, I think my set allows 6 or 7 setting savings, and can recall them I remember in the menu.
It seems a great idea. Putting on the tiny Open Short Load bits unto the SMA port and taking them out can be a bit of pain, if it has to be done often. But saving and recalling the calibration settings for most commonly used frequency ranges sounds solving the problem. cheers. 73.
