Hello Shirley. I am very confused. I feel I need to update my NANOVNA-H 4.
Current version is 1.1.01, build time Dec 20 2021.
The unit has a flickering blue line at the top of its screen. I am hoping an upgrade will help.
I want to use it for SWR for amateur radio antennas. Nothing more fancy that this task.
- I have downloaded and installed STM32CubeProgrammer.
- I have downloaded and extracted NanoVNA v.1.0.69 fw pack.zip.
- I pressed the "wheel button" and turned the unit on. The screen stayed dark. I plugged it into the USB cord. And, nothing.
- I opened Device Manager to see if one of my USB ports was USB2. Nope. All USB3.
What needs to be my next step?
I appreciate your help.
David
