There have been many upgrade suggestions for the correct software to use
when upgrading the NanoVNA-H4 and the instructions on how to use that
code. I have not found anything that is supposed to be golden for the H4.
It has all been see if this or that works. I would like to use the STM
software. Is there a package there that is not a demo but the real thing
and then I need the latest DFU file.

Thanks

Fred,
If you follow *exactly *the instructions in the latest version of the
"Absolute Beginner's Guide" (available in the files section here in this
group), you will have the correct STM software and drivers installed, and
be able to install the firmware updates. If you have upgraded to Windows
11, these instructions have not been well-tested that I am aware of, but
likely will still work. Note that the Dfuse-demo software is not really a
'demo', it is released software intended to demonstrate capabilities of the
STM processors. And yes, the website notes that it is replaced by newer
software, but still has it there for download. I understand the newer
software may also work, but the instructions for its use are not as clear
(unless someone else here can clarify for you).

Thank you Stan. I will give all that info a good read. So what is the
difference between the DEMO version and the latest version?

I don't know the difference. Note that the STM software is meant for
programming / flashing the STM processor chips - so I expect that it is
more full-featured for a programmer.
The only thing we need it for is the driver and the firmware flashing -
which is fully functional in the demo version.

Good evening Stan,

I have had a UID and PW to STM for several years now and tried all this STM
updating the NanoVNA-H4 at least a couple of years ago. I ultimately had a
friend upgrade my Nano using his process that I did not understand. So now
I am trying to do it myself again. So I did the download from STM out of
the book you recommended to me successfully and chose to install the W8
64bit driver and it failed right off the bat. This seems like this was my
major stumbling block back in time. I literally spent a week attempting to
do this and had people telling me to read the book. Well I did this time
and I got the same message.

First, let's just install the driver, not the DfuSE DEMO software.
The driver can be downloaded from the STM32 microcontroller manufacturer's
website:
When you click
on ''Get Software'' the site will ask your e-mail address to send you an
email with a download link. Click on the link inside the received e-mail to
download zip file to your computer. Save the file en.stsw-stm32102.zip in a
separate folder and unzip it. The unzipped file contains four drivers as in
the Figure 51.

The zip file contains drivers for Windows 7 and Windows 8, 32 and 64-bit.
Win 8 drivers are OK for Win 10.
NanoVNA should not be connected to a PC yet!
To begin the installation, double-click the appropriate file, 32 or 64-bit.
If you are installing on Windows 10, select W8 (32bits or 64bits) file.

My system is a W10 64 bit system and I got the message #1626 that the
driver failed to install.

Any suggestions?
