Cannot update firmware on new NanoVNA-H4

JS2OLO · ‎2024-09-03

Hello,

My new NanoVNA-H4 arrived today. I immediately set out to update its firmware to the latest version (v1.2.29) but have been unable to get the DFuSe_Demo_V3.0.6 bootloader to "Choose" the DFU file (NanoVNA.H4.v1.2.29). I get a "This file doesn't have a correct format..." error every time I make the attempt. I therefore cannot update the firmware in my new NanoVNA.

How can I fix this problem?

See attached screenshot.

Thank you,

JS2OLO
