This is a Windows app what made DisLord...

- start the exe file after download, search "upload VNA firmware" button then choose the "NanoVNA H4 v.1.2.24" button for your H4 device...




Yes, possible make a fw update from phone, but I never tried:

for example:
WebUSB
here is the topic:
/g/nanovna-users/topic/34347906#3654

or this:


- also exist some kind of application for iPhone...

- sorry on the picture just the dfu file

- but You can also download the app in the same way.

You can see the picture attached

Thank you for the link, but when I tried I received this message:

404 - page not found
The main branch of NanoVNA-App does not contain the path Win32/Release*

if You see STM32 BOOTLOADER,

- then You can use the app for fw upgrade.

- You do not need anything else, firmware included:

Istvaan,

I went to the URL and received this message: (Sorry about that, but we can’t show files that are this big right now.).

Can you tell me about the app? Will I use it from my cell phone? Will it be an icon on my Windows desktop?

Thank you.

David

I did not know there was an app. I went to the URL and it says that a file this large cannot be viewed at this time.

Thanks, Roger. I've seen plenty of NanoVNA App plots here, but none with phase unwrapped.

for the NanoVNA-H4 the app already included the latest firmware...

here is only the fw:

STM32 BOOTLOADER
is good if you using the app

- here is the latest version from DisLord:

The simplest and most problem-free for firmware update.

NanoVNA App has graph selections for S11 and S21 phase unwrap. This program only works on Windows and I prefer it to NanoVNA Saver for several reasons (easy graph selection, better scaling options, robust calibration, better measurement comparison)

for uploading use nano vna APP

on my v2plus4 and my saa2n (a v2 clone with 4 inch and n sockets) the upload of a new fw is with pressing the left (connectors down) or the right (connectors up) button to switch the unit into bl mode .. in your case pressing the jog dial in is the same as when i press MIDDLE button (not left or right!!) ... so you need to press jog dial sideways? and switch on to get the unit in bl mode (just a guess)

for uploading i use nano vna APP (nice frontend, easy to use and besides using the nano with it you also can make SCREENSHOTS from the nanos display)

Hi John.

My Device Manager says that it is STM32 BOOTLOADER. I cannot seem to get a driver for the software. I went into the location your suggested. Would you have another idea?

Thank you.

David

I have been reading the Absolute Beginner's Guide, especially the pages referring to installing the correct driver, page 37, and following. In Device Manager I see Other Devices, STM32 BOOTLOADER. I have followed all of the steps and no driver can be found. Any ideas? Thank you.

Hello. Reading Shirley's post, it looks like I need BIN and not DFU files for my NanoVNA-H 4. I currently have version 1.1.01.

In the files section is see Lite VNA2 62 v 1.3.02.bin, NanoVNA H v1.2.08.dfu, V2 320x240.bin, and V2 480x320.bin.

I am not able to get DeFuSe Demo v 3.0.6 to connect to my Windows 10 laptop and its USB3 ports.

Thank you for your guidance and help.

Hello Shirley. I am very confused. I feel I need to update my NANOVNA-H 4.

Current version is 1.1.01, build time Dec 20 2021.

The unit has a flickering blue line at the top of its screen. I am hoping an upgrade will help.

I want to use it for SWR for amateur radio antennas. Nothing more fancy that this task.

- I have downloaded and installed STM32CubeProgrammer.
- I have downloaded and extracted NanoVNA v.1.0.69 fw pack.zip.
- I pressed the "wheel button" and turned the unit on. The screen stayed dark. I plugged it into the USB cord. And, nothing.
- I opened Device Manager to see if one of my USB ports was USB2. Nope. All USB3.

What needs to be my next step?

I appreciate your help.

David

MATLAB unwraps phase with a single command line.

Thanks KD8CDG. It is just an exchange at AMZ. Nanovna.com says if buying from AMZ besure AURSINC, which is where I got it.

When you get your refund go here, buy this one...
