Hi,
I have been busy a few hours to try to upgrade firmware of my NanoVNA H4 to 1.2.27.

Tried STMCube progammer 2.9.0, which usually is fine, with the correct 1.2.27 bin file, and get a black screen.
Tried to use STMCube progammer 2.15.0 which is said to work, black screen.
Tried NanoVNA app, after updating the driver to DFU, and 1.2.27 DFU file, black screen.

Fortunately, I was able to get my NanoVNA H4 back in business by using STMCube progammer 2.9.0 and 1.2.14 bin file.
The same day, I upgraded the firmware of my TinySA Ultra with STMCube progammer 2.9.0 without any issue.

This subject has been debated, but if someone has an idea...

Best regards and happy new year.

Georges,
Are you sure you are trying to load the correct firmware file for the H4?
If you try to load the 'H' file or a 'V2' file, it will give a black screen.
And where did you get the 1.2.27 file? If you are upgrading your H4, you just as well get the most current release from DisLord, which is 1.2.40, which is well tested, with additional features. You can get it at this link:

Be sure to choose the ...H4.v1.2.40.bin file for use with STMCubeProgrammer 2.15.0, or the .dfu file for nanovna-app

Hi Stan, thanks for your answer.
I did get the working 1.2.20, and the not working 1.2.27 from this page :
My NanoVNA-H4 needs a SI file as there is no MS in its designation.
I don't see the MS or SI reference in the link to the 1.2.40 update. Does it matter?
I am a little confused about the different versions.
Best regards,

Don't worry about the MS vs SI designation. Both are handled by the firmware.
There is a setting in the 'Expert Settings' part of the menu structure to select the MS or SI part.
The firmware files with MS or SI in their names simply have that setting initialized to the stated value.

I see that on initial load of Hugen's release page, for v1.2.27, it only shows one file for the -H4, and it has MS in its name. But if you click the link that says "show all 17 assets", it brings up the rest of the list, which includes the -H4-SI files. These would be the correct ones for you (.bin if you use STMCubeProgrammer, .dfu if you use DFuseDemo or nanovna-app).

I would still recommend, however, getting the DiSlord 1.2.40 build, at the link I previously gave, since it has new features and a few improvements, which apparently Hugen has not yet merged into his release.

Hi Stan,

Problem solved, your advice was accurate and effective.
1.2.40 uploaded without any issue using bin file and STM Cube Programmer.
Many thanks.
Best regards,

hmm .. i own a v2 (saa2n) and a v2plus4 and have made over a dozen fw upgrades on each but but NEVER used a programmer!!

connect to usb, switch on with button pressed and voila its in upload mode ...

fire up nanovna app and it reacts with " found a v2 in upload mode ... do you wanna upgrade?" ... then select bin file and bingo all works fine

(in very early days used naovna qt but nanovna app works much better in my view)
