First connected image posted for on-coming Newbies to see what it looks like. Please reply back via nanovna-users the following info for my guidance and future newbies.:

? 1.? Do you use FIRST METHOD, SECOND METHOD, or THIRD METHOD to update your device?
? 2.? What is the latest software update to use?
? 3.? Should I use DfuSe DEMO V3.0.6?
? 4.? What PC programs should I load to start out with?

Thanks in advance

Magic! Absolute Magic! Heinlein would be pleased. Ok, now to read the rest in detail. May be a while before I post again, need to dig in now.

Thank you so much,

Roger,

Downloaded en.stsw-stm32102.zip from:



Unzipped en.stsw-stm32102.zip to six files:
readme.txt
VCP_V1.5.0_Setup_W7_x64_64bits.exe
VCP_V1.5.0_Setup_W7_x86_32bits.exe
VCP_V1.5.0_Setup_W8_x64_64bits.exe
VCP_V1.5.0_Setup_W8_x86_32bits.exe
version.txt

Since I run windows 7 32bit, I installed:

VCP_V1.5.0_Setup_W7_x86_32bits.exe

Went through install procedure Got install confirmation. Plugged in nanovna, no bing! Turned on nanovna, no bing! No indication at all anything happened! Go to device manager and find:

STMicroelectronics Virtual COM Port (COM15)

General: Port_#0003.Hub_#0004

Is this what I am looking for. Is everything oi?

Thanks Roger,
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.

Roger
