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.

"You just lost the game." shows on the device listing for Win 10


Robert Mueller 2021/04/24 04:05

What, is any, meaning does this notation mean when I look at "Devices and Printers" at Windows 10?  Attempts to connect to vna- qt have so far failed, but it is early; the VNA SAA V2 plus 4 just arrived.
Can I just ignore this label or does it mean something needs replacement or repair?

Which is the best choice of software to quickly get started?

Thanks in advance for all help to a beginner!

You need to reinstall the Cypress USB driver, see this thread:
https://groups.io/g/NanoVNAV2/topic/82325632

Robert Mueller 2021/04/24 18:23

Thanks, but how did the driver get damaged; is that some kind of external
attack or did something just fail spontaneously? The driver was working
previously and this marking does not look like something from Microsoft.

I have never met a programmer (30 years in the industry) who would put a
line that says:
"You just lost the game." in any commercial software product. The
company would fire
them immediately.

That type of language showing in your device manager would seem to indicate
you have
larger problems with hackers/virus'

Thanks; this tends to support my intuition on the subject. It does seem
like a funny target for a hacker, however. The message appears when I
switch the VNA on and goes away when I switch the VNA off, but at this time
the VNA is the only device using that driver as far as I know. I should
try another VNA which never displayed this message.

Run the program SPYHUNTER, it is free and very effective.
I have it on all of my computers. Some free, some payed for license.

Maybe it's an open source library, where commercial standards are not
enforced? and even commercial products are notorious for "easter eggs"
(look it up).

I find it hard to believe someone's VNA got hacked.

Much more investigation and examination is called for, regardless.

Robert Mueller 2021/04/24 23:06

I tried to connect to a different computer which has not run for weeks but
which is equipped with the Cypress driver. AS soon as I turned on the VNA
it showed the same error, strongly suggesting the message is coming out of
the SAA V2 plus 4 I was watching the place where the connection of a USB
instrument to the computer shows immediately the making of that connection
on the computer screen. I should add, the first computer I tried is
running Windows 10 but the second one runs Windows 7. To me it seems quite
probable that somebody is putting troublemaking firmware into the VNA. Is
there any way to reliably tell whether this particular VNA is authentic or
is a clone already being sold at Ali-Express very soon after the real VNAs
were announced as being available? I suppose then I must argue with Ali
Express to get a properly working unit, along with more delay.

Please let me know if there is any method I can use to verify whether this
is just a one-time mistake at the correct factory or a defective copy which
never came from the real manufacturer.

And by gawd, This hobby for sure has lots of "experts" and most don't know shit from chocolate lol.

This message comes from MCULIB when enumerating the USB device. It
should not be visible if the driver is correctly installed. The phrase
comes from this: https://en.wikipedia.org/wiki/The_Game_(mind_game)

Erich Kaltenbrunner 2021/04/25 05:02

Aliexpress is known for having sold clones of everything.
As you are the first and only reporting this error you should add 1+1=2 and make a conclusion.
If you are able to you can try a Linux system just for fun and research.

I bought mine on Tindie and have no problems what so ever. My laptop is a win10 ryzen7.

OwO 2021/04/25 11:08

There aren't yet any clones of the plus4. The design has many details
that are hard to copy and just copying the PCB isn't sufficient anymore,
but if clones do appear I will update the website.

I will release a firmware update to change "the game" text to something
more helpful.

mdpaige 2021/04/24 22:02

I purchased my Nanovna2 from the approved tindie store and I also received
this message in the Win10 notifications area. It definitely was confusing
and I thought some shady program was showing some message. I googled for
the message and went digging through the notifications but I had no idea
what caused it... To add insult to injury, I lost the game. Glad to find
out what caused this message though.

OWO, I saw the humor in that message and appreciated it. At the same time I
can imagine some people having a bit of concern for one reason or another.

I received my shipment via AliExpress intact and seemingly in good
condition. I hope to have the chance to test it out soon. Thanks for making
a very cool piece of kit.

Fixed in 20210425 firmware:
https://nanorfe.com/downloads/20210425/nanovna-v2-20210425-v2plus4.bin

CONFIG/VERSION will still show 20210225 because the change was made in
mculib and no changes in the firmware source.

Robert Mueller 2021/04/25 11:42

To be honest, the game text is not my problem; not connecting is the
problem. Naturally, getting rid of the game text does "feel" better also
but one quickly forgets that once the measurements are working well.
However, I am glad to learn that the clones are not yet possible; I would
be happy if the folks investing all that development effort could get the
profit from what they have done.

If NanoVNA-QT won't connect but the device shows up in device manager,
then it is a driver issue and usually reinstalling the Cypress driver
(and rebooting) should fix it.

If NanoVNA-QT works fine but nanovna saver isn't connecting on windows
10, see if this firmware update fixes it. I suspect nanovna saver might
be looking for the old device strings, which used to be "Black Sphere
Technologies" (the default in libopencm3). I had changed that after
someone in the discord chat suggested I rename it (as it could be
confused with the Black Magic Probe), but I didn't think it would break
some software. The new firmware reverts this.

Robert Mueller 2021/04/26 14:55

First of all, thanks for the advice on this, However, it interestingly
more complex than it originally appeared. When I first wrote I was using a
ThinkPad running Windows 10. Even with your advice I have basically been
bumping my head against a wall. With a newly installed Cypress driver,
rebooting, and after installing the VNA_QT software (again and again, just
in case), I gave up (temporarily) and I went to an older HP laptop and
after loading the vna software followed by the recommended Cypress
software, the first try worked! This runs Windows 7, and Not Win 10. I
have no idea whether the problem is the operating system or some difference
in the firmware of the two computers (I cannot believe the hardware is a
likely cause) but the difference in behavior is interesting. If somebody
can figure out what is critical maybe this can help others to get past any
similar experiences., or warn them to fall back on an older computer if
worst comes to worst with a newer model and operating system. One can
wonder whether some obscure setting in the Windows 10 is making trouble
here although it is harmless or beneficial in other cases. Anyway, your
advice was the basis of getting things running.
One other thing is that I suspect some slight tweak in the vna could
prevent such problems; I run several quite different devices on the
ThinkPad with no trouble. I should add that I also have an older vna
(probably a clone but I am less than sure of that) and the ThinkPad did not
agree with that either so that old device always ran by itself. Now, on
the HP it also instantly started to operate. Too bad, because the Plus4
will totally replace the old one because the measurements will be better,
leaving the old one as a gift or backup doing nothing until something fails
in the better model.

That was long but if it helps anyone recognize a similar situation it will
be worth the effort.

Good evening everybody,
Yes, I confirm that OwO's firmware 20210425 is the solution to this bug!
I got NanoVNA V2 Plus4 (firmware 20201013) working on VNA-QT (directly on W10Pro 64bit, AMD chipset), but when I tried to use NanoVNASaver-v038.x64 , it could not connect to the device. So, I searched for posts on the topic, and initially I found this:
https://www.gitmemory.com/issue/NanoVNA-Saver/nanovna-saver/390/832432599
So I arrived here and downloaded the 2021045-v2plus4.bin, and after loading into the nanoVNA, all is working fine.

Thank you, OwO !
Best regards -
Bob
