Re: NanoVNA not connecting to DfuSeDem V3.06


 

Hi Mark,

What were the circumstances that seemed to trigger that particular response
in your device?

FWIW I had the same problem. I moved back to the previous version and then
it worked. I'm also using Win10.

I have a bricked nanovna with old firmware that I am trying to update.

The brick seems to be that it picked up an electrostatic charge on CH0
and
now the impedance trace is all over the place.

Anyway. I am trying to update it. My PC recognizes the device on Com6 and
I use the nanosaver app with it.

The problem arises when I try to get DfuSeDem V3.06 (the latest version I
could find from st.com.

The app does not register my device, no matter if I short the boot
contacts or not.

When I short the boot contacts (I mounted a microswitch to these
contacts)
the white screen comes up.

Any help in getting this unit updated would be appreciated. The firmware
presently on it is old, and does not have

facility for either Update/Dfu or Config.
