Mike,
You can just leave the connector empty instead of using the "open" standard. There is very little difference at 1500MHz and below. (This assumes you are using the normally supplied standards which are SMA male.)

Re: Where can I find the latest STM upgrade SW download for a NanoVNA-H4
Unfortunately some users have this problem, due to some driver conflict in
windows. It has been discussed in several prior message threads - search
for dfu driver to find them.
It is possible that the driver really did install, which you can check by
continuing with the next steps in the document which check the driver
installation. If not, likely you can fix it by continuing through the
document, installing dfuse-demo, which also installs the driver. Then
there is a section with details on troubleshooting the driver installation
which you can work through. I remember having to do a couple of these
steps on my system. Make sure for your system that you install the driver
with a 64 in the name (not x86).
If that doesn't work, search the messages as I noted above. A few users
have found that they needed to use a third party utility to clean the
driver installation before the new installation would work.

I am trying to do it myself again. So I did the download from STM out of

major stumbling block back in time. I literally spent a week attempting to

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?

Mike,
The error message means, as Hugen wrote, that you need to update the
NanoVNA firmware because the software you were using did not recognize the
command. So the firmware has not been updated for you, but the software is
waiting for new commands.
Updating the firmware will probably resolve your issue.

The likely cause of your current issue is that when you upgrade from a
substantially earlier version of firmware, you need to "clear config", and
then power-cycle the nano. Thus clears the config variables that may be
incompatible with the new firmware. I think the "clear config" command is
under the config/expert settings menu in that firmware.
There is a newer version of firmware, which has not yet been added to the
files section of this group. It is at DiSlord's github:
Scroll down the page and click.on the NanoVNA.H4.v1.2.00.dfu file to
download it. It will also need the clear configfollowed by re-doing the
touchscreen cal, etc.

Re: NanoVNA 4 version 1.0.? Only save at 800Hz
When you say you "set the stimulation to 7.025 - 7.3MHz for both CW and
SSB", did you press the "CW Freq" menu item as part of this action? And
did you 'save' the calibration to the slot?
Typically when we say we are going to "verify a calibration", we just
attach the 'open', 'short', and 'load' standards in turn, and look a the
display to verify that they each show the correct values, which are a point
a the far right of the Smith chart, a point at the far left, and a point in
the center (respectively).

software may also work, but the instructions for its use are not as clear
(unless someone else here can clarify for you).

It has all been see if this or that works. I would like to use the STM

and then I need the latest DFU file.

Where can I find the latest STM upgrade SW download for a NanoVNA-H4

NanoVNA 4 version 1.0.? Only save at 800Hz
NanoVNA 4 version 1.0.?
I had all slots filled with band segments mainly SSB 5.3305 - 29.7MHz, 3.8 - 4MHz, 7.175 - 7.3MHz, etc. I decided to verify the calibration, I set the stimulation to 7.025 - 7.3MHz for both CW and SSB, then performed the calibration and the slot now shows cw 800Hz - 800Hz. What have I done wrong?
Thank you, 73,

I've been using a 4GB one in my H4, about 10y old. A cheap Kingston. Works fine, no problems yet.
The issues with modern cards I gathered from different projects:
1. the new fast cards 8GB+ are much more power hungry, and need a good stable voltage and well made decoupling at Vcc against GND, a capacitor soldered close to its socket (like 10-22uF ceramic multilayer smd one for 25V)
2. some may not support SPI (I heaven't see any yet)
3. ALL sdcards have got so called "write latency", WL with modern cards is up to 250ms (!!) long. WL means the card does not respond as it provides its internal "house keeping" - like wear-leveling, etc. The WL is a random process, not predictable, and it is always there, usually 5-10ms long in average, but sometimes much longer, and quite frequent. Applications which needs to write a certain amount of data without be interrupted during the write needs a FIFO to overcome the sdcard's WL.
4. modern bigger and faster cards have more options for speed and type (ie voltage levels) of the interface - needs to be maintained within the code properly
5. Timeouts - some cards need more retries or longer timeouts when you requesting something out of them..
