Good Morning to the group,
I have an old VNA, I think it's what is called an H. I'm not sure if it's an original or a clone either. If possible I would like to take advantage of some of the semi newer features that this unit does not have. I have been working to update the firmware but am not able to get the device in DFU mode or maybe it is but it's not showing up in DfuSe Demo software. I know this is a super noob question but feel that maybe another user could give a nudge in the right direction.
I was able to find some of the reference material in the Wiki and did do some searches but so far no hard info on the older unit as to whether or not they are upgradable.
Thanks in advance.
Andy,

Hello Andy, have You Driver for NanoVNA installed? If Yes, see this photo : /g/nanovna-users/photo/0/34671.23266.0?p=Created,,,20,2,180,0 please short VDD+BOOT0 and turn on NanoVNA ---> DFU mode Now start DfuSeDemo and upgrade FW. Brgds Vladimir, dl7pga

Thanks for the reply, Vladimir.
Yes, I was able to fumble my way around and did in fact find that at the
time of writing my first note I didn't have the firmware installed right. I
was able to get that accomplished and the rest came together well with the
directions. Boy oh boy does that new firmware make a huge difference. this
little H model has a whole new lease on life.
Thank you.

last fw version from DiSLord 1.0.69.
Attention! ZIP file has FW for all variants of NanoVNA:
NanoVNA-H
NanoVNA-H4
and for
NanoVNA V2/V2Plus/V2Plus, but this FW works not with newest HW of
V2Plus/V2Plus4

Vladimir,
I got my new H4 in the mail today and seen that the firmware in it was old as well. When I went to upgrade it with the same process I got a new problem with the driver. the USB populated under the Universal Serial Bus Controllers tab and had the below items listed in the picture below.
Is there a different driver process for a new to me H4?
Thanks,
|
Hello Andy!
Have You driver for NanoVNA installed?
Driver for H works with H4 too.
Please not use driver from Windows.
Vladimir

Good Morning,
I didn't make any driver change after having a success story updating my H model. When I plug in the H4 and hold the button down and power on to DFU mode it still is not recognized.

Hello Andy!
NanoVNA-H4 in DFU mode has BLACK screen, not milk white on NanoVNA-H.
Vladimir

Correct. The snag is its not recognizing it or populating in the DFU tool.

I had the same or similar problem last week when upgrading my H4.? It was a driver problem. Windows kept loading the STM32 Bootloader driver and I needed the "STM device in DFU mode" driver ......I found this post by Don KB5QR and it got me on the right road:
/"I ran into the same problem with Windows 10 not seeing my NanoVNA in DFU mode. I found the fix via a Google search that led me to forum on www.deviationtx.com. One of the members by the handle of "Nuggetz" suggested that the driver in use was not the DFU version. This is what he did, and it worked for me:
Connect the NanoVNA and put it in DFU mode. Go into device manager and find the STM device under "Universal Serial Bus devices" (at the very bottom of the window). Expand this item and you will probably see "Hub Controller" and "STM32 BOOTLOADER". Right Click on "STM32 BOOTLOADER" and select update driver then choose "Browse my computer for drivers". After that, select "Let me pick from a list of available drivers on my computer".
The driver choices you see there should include "STM device in DFU mode". Select the DFU mode one and that'll do it.
If you don't see both "STM32 BOOTLOADER" and "STM device in DFU mode", /_*then you probably need to install the driver using the dpinst_amd64.exe utility, found in the Win10 folder under Program Files(x86)/STMicroelectronics/Software/DfuSe v3.0.6/Bin/Driver.*_/

Hope this Helps.

That's what I needed. I will give that a try when I get home tonight.
Thanks, Dave!

In my case I had to actually go to the mentioned folder and install the "STM device in DFU mode" as it did not appear as one of the choices of available drivers.
Hope it works for you...let us know. Apparently this problem is not uncommon as the correct driver installs automatically for some but not others.
Thanks again to Don KB5QR who's post helped me out.

Sigh....
I tried to uninstall and reinstall it sven different ways to sunday but no luck. The reply I keep getting is the driver I have is the best.

It looks like there is a problem with the USB connection or the MCU is not entering DFU mode correctly, can I see a picture of the inside of the NanoVNA?

Hello All,
I am new to the group and ended up here as I had major problem upgrading the firmware in my NanoVNA-H. I may have missed a crucial piece of info in my approach (please flag it up if I have!) but now I want to share my solution how it worked for me. I had the same issue of previous members with DefuSeDemo not recognising the VNA in Windows10, first off-the supplied USB cable does not work but you do get the message on windows stating a device has malfunctioned giving you the impression it's not just a charging lead, change the lead first! So I went down the Zadic route of installing the drivers which got me further to the point of 'STM32 BOOTLOADER' now showing in device manager under 'USB Devices' but I could not get it to show "STM device in DFU mode" in device manager even though the VNA was definitely in this state. I could not get past this stage no matter what I tried so I gave up on DefuSeDemo and tried STM32CubeProgrammer loading the v1.0.4.5 bin version (changing from V0.4.5.1), and it worked immediately, no issues! Hope this helps someone else.
|
I have a USB 3 on the PC that has an 8 port hub plugged into it, I can't use that hub it won't see the VNA. Now plugged into that hub I have a unit that has 2 USB 3s, 2 other USB and 2 slots for inserting disc drives. I can use the USB 3s on this unit with no problems, even though I can't get a connection using the hub it is plugged into!!??
