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.

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 )

maybe you saved files without doing a full calibration (SOLT) so there are values missing? dg9bfc sigi ps as i have noted .. 1.3.15 is newest Am 05.03.2023 um 02:27 schrieb TheSpud via groups.io:
