Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Trouble with NANO VNA Saver


TGundo 2003 2021/05/21 21:09

I finally got my V2 Plus4 from the official store. I had a clone previously and returned it to get the real deal.

I had the clone working fine with NanoVNA Saver. I cannot get the official one to work.

Running 0.3.8.

I can connect fine to the V2 Plus4 using NanoQT, I assume everything is ok with the PC and driver.

The Nano comes up on COM5 with the proper driver in the Device Manager.

I've tried everything I can find on all the boards & forums with no luck. Nothing ever populates in the serial port field on NanoVNA Saver.

Any help or thoughts?

Thanks!
Tom

This topic has been already discussed.The solution is to update the firmware to the last release.
I did it and it works

NanoVNA Saver creates a folder in this path:
C:\Users\your account\AppData\Roaming\NanoVNASaver
Try deleting the NanoVNASaver folder which is used to keep your previous settings.
In many cases it solves the problems.

I deleted all files (two .ini files) under
%USERPROFILE%\AppData\Roaming\NanoVNASaver\, the NanoVANSaver still
crashes while connecting to the device.

Deleting the ini files did not work for me either. I flashed the latest
stable firmware in the (now obsolete V2.2) and then it worked!

Unfortunately my hardware is version 2+4.
