Problems Upgrading firmware on nanoNNA H4.


David Grace
 

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 ?
