Roger,

Came back in and checked eMail one more time. I have gone to both URL's and downloaded en.stsw-stm32102.zip and NanoVNASaver.x86.zip. Since I run Windows 7 32 bit, that looks right. will get after this Wednesday. Gone this time. Will let you know via private eMail rain or shine. Thanks a million.

30, Billy

Billy,

I understand your frustration so I will help get you started.

The NanoVNA uses 2 drivers to communicate with the PC. One is when you want to exchange data with a terminal or application program like NanoVNA Saver. The second is when you want to update the firmware by loading a "DFU" file.

In this post I will only cover the first.

Windows 7 does not have the driver installed for exchanging data so you have to install it manually. The procedure to download it from ST is cumbersome and requires registration for some reason. So I have placed it on my Box clouid drive for you to easily download. Here is the link:



Once you have successfully downloaded it you need to unzip it and install the driver Win 7. There are 32 bit and 64 bit depending on what type of CPU you have in your PC. Do not plug in the NanoVNA until after you have installed the driver. When you plug in the NanoVNA after installation you will hear Windows "bing" and you will set it in the Device Manager as a COM port.

Next step is to install NanoVNA Saver. You will find it at this link.



Download the Windows 32 or 64 bit version, unzip and install. Then run it and patiently wait - it often takes 10 seconds or so to load because it is a Python program and it unpacking the support routines. Then in the bottom left hand corner it should show the COM port of the NanoVNA (Rescan if necessary). Click "Connect to Device" and it should plot in the graphs.

This will get you started. In the Wiki for this group and on Youtube there are tutorials on how to use NanoVNA Saver.
