But notice there is NO pip-install directory.

Check under /usr/tmp and /usr/local/tmp and see if there might be a pip-install directory in there somewhere.

I'm reporting my experience with the Web app in case it might be helpful to somebody.

I opened the web page on two Android devices. They are versions 5.3 and 6.0, which I know are old, but both worked with a USB memory stick so I know that the OTG cable was good. However neither one would connect to my NanoVNA. Both said "Error: Failed to open. Error: failed to claim interface". I guess the NanoVNA firmware is too old or something. The firmware works fine for me as standalone so I don't want to upgrade it at this time.

After that, I installed nanovna-saver-v0.2.2 on Windows 10. The NanoVNA connected and transferred the scan to the graphs, so that worked.

We are very sorry for this situation, it seems that the touch screen was damaged during transportation, if you buy a model made by us, we can provide the accessories for free, please contact your dealer. If you buy through alibaba, we will send you a new one for free.

Check for us, please. Does this file exist?

If you search for it, can you find a file somewhere in the file system named "setup.py"? (Probably in a PyQt5 subdirectory somewhere else.)

Do you actually have a tmp directory in the root?

Hi Chuck,
i see you need to install a driver on windows 7 so that your computer can see
nanoVNA. To do this, download and install en.stsw-stm32080.zip (DfuSe) or
STSW-LINK004 (ST-Link) or en.stsw-stm32102.zip (STM32 Virtual Com Port
driver). DefuSe or ST-Link is required for a firmware upgrade.
After installation, plug the nanoVNA connector into your computer's USB port.
Use the USB cable (not OTG) supplied with the nanoVNA.
I don't know what the usb connector of white nanovna.
You can see in the device manager of your computer that it is present at COM &
LPT.
If not, a little utility (USBDeview) will help you to remove the faulty driver.
To run nanoVNA-Saver on Windows 7, you must have the SP1 Service Pack
installed and MS VC ++ multipack (2005-2017) installed, then the windows exe
version of nanovna-saver will work. It starts up slower when you first start
up, later it is faster.

Hope I was able to help with the solution.

================================
Gyula, thanks for the feedback.

I had attached a PDF including the information I had hoped would show the problem and system information for my computer. I've attached it to this message for reference.

This problem is above my level of understanding and knowledge. The list of ports and drivers is included on the PDF. Which is what and correct or wrong is not obvious to me.

So then, I'll need to educate myself and hope to figure out what is what from the information you provided. I believe I do have the correct connection cable once the other problems are corrected.

Regards,

Thanks for the ideas, guys. There was a tiny amount of plastic film under the bezel. But, removing it made no difference. Operating with the bezel off is no different, either. There does not seem to be a visually detectable problem. Bob W7PUA

I have this book and it useful.

But it's mostly about the NanoVNA history, features and functions and not much about step-wise setup, use and worked examples.

This one has more about useful applications and how to make measurements. Not so much with step-wise instruction but many worked examples.

Hi Jim I don't see where my program starts. But it does (is it compile?) Go
thru the process of trying to get there.
I was wondering if I loaded a Python IDE and tried to get the program to
run from there if I would have a closer look at the problem. There are a
whole lot of tools to use in the world of Linux maybe I could put one to
use. I think it would take a whole lot of videos on YouTube to get me up to
speed.!.

That might be the same error message I got when I installed the
latest Nanovna-saver yesterday. The program still starts, but I haven't
tried actually connecting to the NVNA.

Your plot should be a little tighter together. Did you calibrate the NanoVNA before attaching the cable?
The plots below are 30 cm of RG316 with an open BNC connector on the end. One up to 299 MHz. and the other up to 900 MHz. offset delay was set to -1536 ps and no calibration done in NanoVNA saver.

I'm getting a program crash when enabling Continuous Scan after loading a
calibration file on 0.2.2, Win7 SP1. Anyone else seeing this? I've posted a
new bug issue on Github.

Here is a picture when running a stylus all over the screen in a touch test

Take the four screws holding the screen bezel down, and check to see if there aren't scraps of the plastic film still stuck under there. I had that problem for a few minutes when mine arrived, until I noticed a tiny corner of the film sticking out of the bezel.

It sounds like you may have a bad touchscreen or, make sure that
There is nothing pinching the touchscreen around the front bezel.?You can remove the 4 screws on the front bezel and do a visual chaek ofnthe touch surface.?

Rune,

Thanks for fixing the "Offset Delay" bug in Calibration. I checked it out with several coax cables and got good results. It also correlates with the "electrical delay" parameter in the NanoVNA hardware.
