I downloaded nanovna-solver64 from github, installed LabView and NI-VISTA from the NI website. The COM port associated with my nanovna-H appears in the NanoPort drop-down list on solver64's Setup/Diagnostics tab, but pressing LINK does not produce the desired "green light" status indication and the control wheel on the nanovna-H remains active.

Can anyone tell me what I have failed to do? Or, is the nanovna-H not supported by solver64?

After rereading the docs, I did a proper clone of the github repository and used the author's preferred unzipping tool to recreate the directory. Program startup found defaults.set, which was missing from earlier (improper) installation.

But, LINK to nanovna-H still fails, producing error code 1073676294 from source "VISA Read in NanoVNAPlus_r3_01.vi". I am using the supplier's (ttrf) firmware v0.8.0-20200620 ( https://github.com/ttrftech/NanoVNA/releases ).

Clues?

Brian, this firmware is to old.
In attache is version 1.1.01 from DiSlord
73 de Vladimir, dl7pga

I think not work with the NanoVNA H is different protocol of NanoVNA V.2

Thanks for your suggestion, Vlad. The new firmware did not fix my problem.

NI-VISA package installs utilities. Running nivisaic (interactive control
utility) finds the device on COM6, but returns this message:

Error opening resource:
ASRL6::INSTR
VISA: (Hex 0xBFFF0072) The resource is valid, but VISA cannot currently
access it.

The NIMAX utility also finds the device on COM6, but reports the speed as
9600 even though the firmware (CONFIG>CONNECTION>SERIAL SPEED) reports
38400. Maybe this doesn't matter if the connection is USB.

Thanks, Francesco. I think you are right.

The old version 32bit work with NanoVNA H

Thanks, Francesco. Can you show me a link to the 32-bit software? I can't find it on github. Perhaps it was removed when the 64-bit version was released?

I have been using Sharp. It is fine to generate sweeps and download Touchstone files, but I would like to use the additional features of Solver.

Hello the adress is this :https://github.com/joeqsmith/NanoVNA_Software

the 32 bit software still there.

See the attached picture.

First instoll the version 0.10 and afer on 3 you found the software for the
NanoVNA H

Thank you for the clear instructions, Francesco. Reading the documentation,
I see that I must first go back to the ttrftech 0.8.0 firmware.

I will update if I am able to make this work.

Brian,
https://github.com/joeqsmith/NanoVNA_Software/blob/NanoVNA/NanoVNA_original_2p10.zip - after installation of version 0.1.0 please unzip and copy this programm for nanoVNA-H to folder of main programm
https://github.com/joeqsmith/NanoVNA_Software/blob/NanoVNA_V2Plus/NanoVNA_V2Plus_2p08.zip - unzip for NanoVNA-V2Plus/Plus4 ---> to folder of main program

Vladimir

Screenshots from my computer.

Thank you, Vladimir. 2p10 works with my nanoVNA-H using ttrftech 0.8.0
firmware. I am very grateful for your help.

Brian
