And also screen capture now working on all versions.
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.

Firmware on all V2 versions now bug fixed
OneOfEleven 2020/11/07 10:15
Just need DiSlords firmware updates to trickle through for the firmware files to become available.
The mouse dragging lock ups on the VNA itself have been fixed.

Where would I find a download link for the NanoVNA-App by OneOfEleven? It looks a lot more feature rich than NanoVNA-QT.
Thanks,
Neal

It's here ..

But I haven't yet added the calibration routines so is current;y of very limited use with the V2's. All I've so far done is get it talking to the V2's, still debugging/optimising the comms code at the moment.
Neal Pollack 2020/11/08 15:53
OK, very good. No need to apologize for it not being totally done yet. I can at least experiement and learn. Since work is VERY busy for me,
I have limited time to play with this anyway. You will likely been done with debugging the app and adding features long before I get bored waiting :-)
Thanks very much for sharing the app while it is still in progress. I appreciate it.

Dear Cathy,
Thank for your efforts in pushing the support of the NanoVNA-V2 family. I have tried the Capture VNA Screen function, but it does not work for me (versions 1.1.131 and 1.1.135). I also own a NanoVNA-H (2,8") and it works lile a charm with this equipment.
Below are details :
- NanoVNA V2_2 Gold Version with 3,2" screen (320x240) - FPU enabled
- Tested with official firmware (20201013 version) and alternative "Koubou" firmware (binary20200913test)
- PC operating system : Windows 7

I know that you are very busy, as you also provide support to Erik for the tinySA App. I hope that these informations will be helpful, don't hesitate for asking for specific tests. As an other member says, your application will be nearly perfect when you will introduce calibration (SOLT) steps, which are required for working correctly on a remote basis with a NanoVNA-V2.
Once again thank you for your valuable work.

Thank you Siegfried for your advice.
Indeed, the screen capture works now with this version of firmware from Dislord. What I have seen interesting with the "Koubou" software is the possibility of defining narrow RBW values (up to 10 Hz), which is very useful in some situations. This feature has also been included in versions from OneOfEleven for NanoVNA-H family. Im am not sure, but this feature seems not available in this V2 firmware version from Dislord.
Once again thank you for your help.

OneOfEleven 2020/11/09 02:38
Hi Jean-Roger
The V2 firmwares have no option to set or change the RBW unfortunately, so external software cannot request the firmware to change the RBW.
In fact, the V2 firmwares don't allow anything to be changed at all via the USB connection, all they allow is too start a scan/sweep and read the resultant data, nothing else can be done via the USB, the V2 comms protocol is severely limited I'm afraid.
I think you'll have to ask the V2 firmware developers to change that if you want more features via a USB connection.

I use original firmware from github (this allow add all this changes in futute to it), add only fixes for new capture screen feature (add correct support for all displays), also fix some exchange vs LCD (this fix hang on long marker dragging)
Additional OneOfEleven ask for more simply get all points data from device, old protocol limit point count from one scan by 255, and software need several ask for more. I add if ask 0 ponts, device send all scan points data, this allow more easy read and not lost data.
I try not add features by selа, i not want made another firmware as for example https://ojisankoubou.web.fc2.com/nanovna/nanovnav2.html#document, not matter how it good, it lost support after autor stop it. More better way - one official firmware vs added features, this give chance in future update
Jean-Roger Roy 2020/11/09 03:04
Hi Cathy,
Very interesting to learn, as I dont't feel very comfortable with these aspects. Now I have a better understanding of limitations. When you say "nothing else can be done through USB", I think it does not cover the CAL commands, as QT or NanoVNAsaver (0.38) allow these remote calibration steps.
I can also understand that improving or adding functions deal to less motivation, due to these limitations.
For me the RBW adjusting feature (at least as existing in Koubou firmware) is very useful. So for the moment I think that I will go back to this firmware version.
Once again thank you for your extensive work.
Jean-Roger
Siegfried Jackstien 2020/11/09 11:10

will also be added to the official fw

Sorry Dislord,
I have not seen your answer, that has appeared just after pushing my answer to Cathy.
Thank you for additionnal comments and position concerning firmware features and developments. I have an additionnal question for you, which maybe is not relevant. As I explained to Siegfried in a private message, I do not feel comfortable at all for compiling source code files. Is there a technical reason or other such as regulatory reason, why in the release section of your Github there is no "ready to use" bin files as often proposed by other developpers ?
Maybe it is a silly question, already answered !

that is wrong ... calibration when used on pc is done inside pc (you do
not calibrate the device but the software)

if you can not control the device by usb then there is notzhing you can
add in functionality

i hope that some of the code from ojisan fw make it in the official fw
... there are a few nice things in that fw and making a "mix of both"
would be best
