Hi
I'm wworking with Windows 10 and when I click on the link that Herb advises I get a blank screen in my browser (Mozilla FireFox), however my NanoVNA-H4 works well with the "Teraterm" terminal softwarte, you could try that one as well.

Jos,
FYI, the browser link only works out of the box with the Chrome browser. Internet explorer requires a special driver, and from your response I'm guessing so does Firefox. What's really strange with Rick's H4 is that he can charge from the USB port, he can put the unit in DFU mode and load firmware from the USB port, but cannot establish comport communications via the USB port.
The above indicates the hardware is O.K. but that the serial port driver is not working. The NanoVNA-H4 uses the STM32F303CCT6 and it supports serial communications via a virtual comport (VCP). I checked to see if there was a Windows 10 driver at but the Windows 10 native STM32 VCP driver is recommended:
"The STSW-STM32102 software package contains four installation files based on the various versions of the Microsoft? operating system.
OS versions prior to Windows? 7 are compatible with the Windows? 7 installations included in the package.
Starting from Windows? 10, the STSW-STM32102 driver is no more adequate and the usage of the native inbox driver is recommended. "
I thought when Rick tried loading the x64 VCP driver from the ST web site that it might have messed up his configuration, but he tried connecting to another Windows 10 PC and also could not establish comport communications.
Very puzzling.
