Hi

I am having problems (i can't calibrate) with OneOfEleven NanoVNA-App, I am using the nanoVNA V2 plus4 model maybe its not compatible with that model. here is what i have done so far:

re-installed USB driver
I tried 2 other computers, same problem ( Windows 8.1 and Windows 10)
I tried another USB cable

here are two videos so show what is going on:

part 1 video:


part 2 video:


any help would be great! thanks

what fw is on the plus4?? (i use 1.3.7 from dislord)
next is .. i see you are using version 209 of the nano vna app
but there is a newer one
so .. with new software and new fw here the plus4 just works fine
i can calibrate on the device or in the nano vna app
both do work fine
dg9bfc sigi

yes i have to flash dislord but i want to backup my firmware first what is the best program to do that with?

Thanks
