Re: Problems Upgrading firmware on nanoNNA H4.


 

If you have DfuSeDemo installed, what is preventing you from doing the upgrade with it?

Oh, and when in Dfu mode, the Nano's ID changes, so you would see it as a Dfu device, not as the NanoVNA - that much is normal.

I have been unable to carry out this update. I currently have vesion 0.5.0.
I have downloaded several newer versions, have DfuSedemo installed with up to date drivers - did i say i am using windows 10.
I have aslo got NanoVNA-APP installed. this recognises the vna and will download screens from it which indicates that the lead i am using is ok, but when i put the vna into dfu mode it no longer recognises the vna.
I have tried all this in 'administrator' mode without any luck !
Help - what am i doing wrong ?
