I hope someone can give me some information regarding firmware for my NanoVNA SAA2N
I have bought and just got a NavoVNA-SAA2N, and is a bit confused about which firmware to use. I'm a bit disappointed as this unit does not have the same console command interface as the the other NanoVNAs, the one I'm missing is the screen dump function. I think I have seen some place that the firmware for these utnits have been upgraded with a screen dump function, but I cannot find the message.
To be sure about my unit, I have the following description, "black metal box" with 2 N-connectors and 3.95" screen.
Label on the back:
SAA-2N
Simple Vector Network Analyze
Freq 50kHz-3GHz
HW version 2.2
S/N N2010xxxx
Made in China by Zeenko
Display following information on screen:

I have checked the github mentioned above, the "ttrftech" seems to be ok, the screen shows a version from 17. June 2020, but on github the there are a version from the 20. June and the one from 21. March. The version from the 17. June is not there.
I suppose the version 0.8.0 from 20200620 is ok for my unit.
Another site is also mentioned on the screen, https://github.com/nanovna/NanoVNA-V2-firmware. Here, there are newer versions, lik the one dated 20201013. I go to the link: https://nanorfe.com/nanovna-versions.html to find the correct version for my unit. But the only version 2.2 I find only have a 2.8" screen. I conclude that none of the firmware version at this site can be used on my unit! Is my conclusion right?
Are there any other options for working firmware versions to my unit?
