My Android phone has always worked with the NanoVNA app and I now get a “No Device Found” error.

Any ideas, please?

C connector to C connector cable which works fine using NanoSaver on my laptop, so that's not it.

I am certainly no expert here, but my experience points to a
security setting?

If I recall correctly, I tried the app with my newer USB-C connector phone, and it didn't work either. Not without the OTG (On The Go) adapter which I had to use with the older phone.

Both VNAs have worked fine before, but now both have the same problem.

No change in settings that I can see.

A local ham came around on the weekend with the same problem.

Frustrating!

Try it re-install: /g/nanovna-users/wiki#Android-NanoVNAC2A0app

Hi, Gyula.

I tried that with no change.

Changed a few known working cables, but no luck.

Frustrating!

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)

Thanks, Gyula.

I use my NanoVNAs with the nanosaver and NanoVNA-App apps on my PCs, with no problems.

I just want to be able to go back to using them with my 'phone.

I am sure that the Linux users will be grateful for your information on that.

Where can I find v1.1.211 please?

Sigi, it doesn't work for me. This is the last one that goes well.

Chris, the author has a github page here.
This page might help:
If you know this, then I must ask for your forgiveness.

Which Documentation folder did you put the .exe file in?

Was it /home/pi/Documents or Wine's virtual My Documents?

Mike,
Yes, in this. You can do it somewhere else, only when you start Wine, a window opens and it's there next time.
