64 bit system and loaded 32 bit dfu tools, so no compat driver? -- Sent from my Android device with K-9 Mail. Please excuse my brevity.

Well, It may be related to Windows 11 and I have only Windows 10 machines. Sorry I can't be of more help.

Hmm. That file is there but when I point to it, windows 11 says it’s a non compatible file and if I choose to use it the system mdt become unstable. I chose it anyway and the when going back to the

I have Windows 11 pro so maybe that’s the problem. What is the actual name of the file? Thanks Steve

OneOfEleven developed the NanoVNA App for personal use and after moving on to other projects kindly posted it as open source for the community to use and modify. Owen Duffy has created a fork of the

The calibration algorithm takes a bit of effort to understand. It was discussed in a previous series of posts. /g/nanovna-users/topic/68975032?p=Created%2C%2C%2C20%2C1%2C0%2C0 There

Hi Sigi, I have identified the problem. I was naming my saved files as XX-METER, for easy identification. But recalls always failed. So I tried saving the file as XXMETER, with no dash, and it worked.

Does not find the STM Device in DFU Mode file. I manually tried to locate and it is not found anywhere. I searched both rprogram x64 and x86 STM Electronics folders and cannot find a compatible

@Roger, thank you for these tests that confirm the problem, you did a good job! @Siegfried - after all, the whole topic is about getting an incorrect result despite calibrating the cable. Did you

Sigi, let's just say yes, today DiSlord uploaded v1.2.20 for NanoVNA-H and NanoVNA-H4. v1.3.15 still applies to NanoVNA V2 family and LiteVNA! :D -- Gyula HA3HZ ( http://ha3hz.hu )

I use my NanoVNA from 0.4 to 150 MHz. I wonder of installing a 10uF coupling capacitor with the 1uF would help the low frequency response. Can anyone recommend a SMD part from Mouser or Digikey?

Steve, I had a similar problem. DFUseDemo was loaded with the Bootloader driver which I use with STM32 CubeProgrammer for my Malahite DSP2 receiver. It uses the bootloader mode to update firmware.

I got to the point of starting DiFUse and also downloaded the latest firmware. Following the directions in the beginners guide I started the DFU demo program and started the nano in DFU mode as

Hi Igor, if you still need a new display, I recommend this one. In 2020, during an installation, a warm part softened in the middle of the display and left a mark. So I ordered and tested a new

TheSpud, I recommend a complete memory wipe before uploading the new firmware. That will probably help. link: http://www.ha3hz.hu/images/download/DMR-Clear_Memory.zip -- Gyula HA3HZ ( http://ha3hz.hu

Hi Sigi, You are talking about NanoVNA v2, where 1.3.15 is indeed the latest. In contrast, 1.2.19 is the latest version for H and H4. -- Gyula HA3HZ ( http://ha3hz.hu )
