Hi all, in April 2020 I purchased a NanoVNA H with the following characteristics:
Based on edy555 design
Licensed under GPL see https: // etc ect
Version 0.4.5-1-gfbbceca
Build time: Dec 26 2019 - 19:32:31
HW version 3.4.
Then I updated the firmware to version 0.4.5-4 of 1/18/2020. From that moment on I have not updated because I noticed that there are many Hardware versions, many specific firmware and I was afraid to make it a brick. These days I wanted to check if there was any new firmware and looking a bit on the web both on the Hugen portal and on our group, I saw that the latest firmware are NanoVNA-H-SI_20210130.dfu and NanoVNA-H-SI_20211230.dfu . Of these latest firmware I have seen that there are 2 versions, the MS and the SI, which are respectively for the SI5351 cpu (that of mine) and the MS5351.
I first installed the NanoVNA-H-SI_20210130.dfu firmware very easily (having already installed dfu drivers and software because I often update Tyni SA with DFUSE 3.0.6.)
I noticed that the characters got bigger and there were other functions. Then I wanted to install the latest firmware: NanoVNA-H-SI_20211230.dfu
I noticed that there are even more functions and settings even the date and time and the possibility of using an SD card.
Considering that my version is the NanoVNA H 3.4 with 2.8 "display, I would really like to know which is the most suitable and compatible firmware. I would not mind leaving the latter NanoVNA-H-SI_20211230.dfu installed because it is really complete. Rather, where can I find a guide that explains how they are set up and what are the usable functions it has in addition (example I use sd card. Many thanks for the help
