Re: #general SD card function on H4
#general
Hi Rudy.
I own a H4-clone (hardware version 4.2.1).
It came with the soldering pads free and no Transflash connector soldered on it.
I provided for by myself.
The RTC quartz was missing too and I installed it in the same time of the MicroSD slot.
When I try to save a screenshot I obtain the same error like you:
Fail write

More precisely, the writing of the .BMP file starts but it remains of length 0 and so in the memory card I find the BMP files created but empty.
I reformatted the SD card as FAT, FAT32 and exFAT also.
That didn't solved.
The very strange thing is that I have no problem instead to save S1P, S2P and firmware dump as .bin (about 250kbytes of data).
In those cases the data saving goes perfectly.
I recently reflashed again last release of DiSlord firmware: 1.1 of 2021/12/11.
I lost all my settings and even didn't solved.
Firmware bug?

1. "Is there a schematic published?"
The LiteVNA is not open source so hugen has not released a full schematic. This is not intended to impede users, but rather to slow down the inevitable introduction of LiteVNA clones. If a user wants to make a hardware modification to his LiteVNA, hugen has released a partial schematic to assist him on request.
2. "One issue with some of the later variants on the original NanoVNA is that they are *much* more sensitive to ESD (because they use RF switches on the inputs).? The NanoVNA has resistive pads/bridges and is pretty tolerant to ESD and weird voltages."
The LiteVNA uses the same input ESD protection introduced on the tinySA spectrum analyzer that hugen also manufactures. This was pre-emptive addition to ESD harden the input of the LiteVNA.

website language selection (HA3HZ)
The language selection feature doesn't seem to work on Safari, Chrome, or Firefox (MacOS Big Sur) - I think that something is not causing the translation to work, or it to re-render - If one selects a different language, it shows up as checked the next time, but no translation occurs.
Chrome does bring up a dialog offering Google Translate, which does work.

Re: Nanovna-H4 / F - Very Large Font Firmware?
That firmware was created 2 years ago by forum member REALD.
There was only a few releases and the H4 had not been released at that point in time.
The last release of that firmware was Dec 2019.
If you want to contact the author or grab a copy of his source code, his github is:

Hi Gyula,
Yes, I am using Windows 10.
Are you saying that Windows 10 updates disassemble the DfeSeDemo driver??
Does 'disassemble' mean 'make the driver non-functional'??
And are you saying that nanoVNA-App uses this Driver to update the Firmware??
If so, then I think I should be okay ...

Hi Ian,
I assume you are using Windows 10 where in my reading, the updates cause an error to disassemble the driver that has previously been installed.
Therefore, enter the DFUSE V3.0.6 directory where you can find the necessary drivers in the BIN Library / Driver subdirectory.
You will find a folder corresponding to your operating system where you can install the driver again with the EXE file.
I hope this was the reason for your failure.

I am very happy with my H4, and would definitely get it, unless your
primary use case is at frequencies in the GHz range. The V2 plus4 has a
purportedly better design for the highest frequencies, and has a top freq
of 4GHz, if I remember correctly.
But for HF and VHF useband non-critical work at the higher GHz frequencies,
I don't see much advantage to the V2. The H4 is an excellent device and has
more active firmware support, which has resulted in some excellent
features.

Thanks Gyula, H for Hugen and D for DiSlord .... simple ..... :)
I have connected my nanoVNA to the nanoVNA-App and it is recognized on COM3 etc..
However, when I then put the nanoVNA into DFU mode using the nanoVNA Config Menu ... COM3 shown in top righthand corner of the nanoVNA-App disappears and a message is displayed stating that no DFU device is connected and the Firmware will not upgrade ... see Error message ...
"Loading "D:\OneDrive\Electronics\Test Equipment\nanoVNA\nanoVNA software upgrade v1.1.00\NanoVNA.H.v1.1.00.dfu" ..
94825 bytes loaded OK from D:\OneDrive\Electronics\Test Equipment\nanoVNA\nanoVNA software upgrade v1.1.00\NanoVNA.H.v1.1.00.dfu
DFU element address [0]: 0x08000000
DFU element size [0]: 94516
Firmware size: 94516 bytes
No valid DFU device found
Have you put your NanoVNA into DFU mode ?"
I checked the Device Manager and "COM3' under "Ports" disappeared (as I believe it should?), but 'Other Devices' appears with "STM32 BOOTLOADER"
I believe that this is the file/software used when upgrading firmware via the DfeSeDemo software .... which I have used previously.
My knowledge here is very limited .... is this blocking nanoVNA-App form upgrading the Firmware??? Do I need to delete it??? Rename it?? Is it this file ....
"DfuSe_Demo_V3.0.6_Setup.exe" ???
Any help is appreciated ....
