Beware of cheap underperforming clones

As of 2023 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.

Hi, you can download the official firmware updates here: https://nanorfe.com/nanovna-versions.html
The next firmware release for the V2 Plus4/Plus4 Pro series will come in a month, with a few bug fixes and usability improvements.
Thanks

Hello Sigi,

can you provide a link to read more about this alternative FW ?
I try to search in the web but I reach only old repository with 2-3 years old versions.
Changelogs differnce and fix ?

Thank you sigi.

To your question IW6BFE

As I have researched there is a group with updated firmwares into https://groups.io/g/nanovna-beta-test.
You have tu ask for the subscription and then go to Topics.

Regards.

You are going tell about it here in the forum too, aren't you?

I ask more info about that but seems that @nanovnasupport do not reply to customer questions.

Hello All,

all of us expect to get new firmware in next 9-10 days this is the month after that nanov2support announce it.
I hope to receive with new formware also a changelog ...

What I really do not understand is :
In the official github repositori lastes available version is 20201013 https://github.com/nanovna-v2/NanoVNA2-firmware/releases

In the official webpage lastest available version id 20220814 https://nanorfe.com/nanovna-versions.html

Would be great to have only one reference with a readme file with listed all version with changelog and improvements

This is only a my problem or some other user would like this ?

Arrio

István 2023/09/11 14:09

Yes, many of us are really looking forward to the new firmware.

But please don't put pressure on the developers, because then it will never be finished.

IW6BFE 2023/09/12 01:13

I think you don't understand my question.
Changelog is not a pressure.
You will load a new firmware whit non known changes ?

I purchased my nanoVNA V2 Plus4 in July 2022.  It came with firmware version 20220301.  In January 2023 I was interested in finding out if a firmware update was available.  On the nanlRFE website, in the Hardware Versions/Firmware Downloads section, firmware version 20211227 is listed as stable and version 20220814 is listed as latest.  Version 20220301 is not listed.  I wanted to get a copy of version 20220301 before loading any version of firmware so I could get back to what I currently have in case of issues.  Since I purchased my unit on Tindie I contacted them about obtaining a copy of version 20220301 and asked about the stability of version 20220814.  Following is their answer.

" Hi, the 20220301 version can be found at:
*https://nanorfe.com/downloads/20220301/nanovna-v2-20220301-v2plus45.bin* ( https://mandrillapp.com/track/click/30145078/nanorfe.com?p=eyJzIjoiSE50OWRZS0pGNmdQekFyeWFFWUU5emZiZWkwIiwidiI6MSwicCI6IntcInVcIjozMDE0NTA3OCxcInZcIjoxLFwidXJsXCI6XCJodHRwczpcXFwvXFxcL25hbm9yZmUuY29tXFxcL2Rvd25sb2Fkc1xcXC8yMDIyMDMwMVxcXC9uYW5vdm5hLXYyLTIwMjIwMzAxLXYycGx1czQ1LmJpblwiLFwiaWRcIjpcImQyYTBlZmVlYTU0YjQ4ZjBiNDkxYTUwYWFhNjcxY2M0XCIsXCJ1cmxfaWRzXCI6W1wiODU2MTRlOWE2MTViOWYyNzZlNTk1NWUzMmQxMTRiZDJkZGJlZmRlN1wiXX0ifQ )
20220814 has been tested for some time now and is considered stable. We may release another firmware update next month to add a few features requested by users.
Thanks"

As you can see they indicated a firmware update might be available in February 2023 but I haven't seen one yet.  It will be interesting to see if one shows up in October 2023.
