Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Using The ST Tool Dfuse with the S-A-A V2

Sam Reaves 2020/07/22 08:32

It would be useful if I could figure out how to use the ST Dfuse DFU tool for updating firmware for the V2 just like the NanoVNA H and NanoVNA H4.

I took the .BIN file and converted it to a DFU but the ST Dfuse tool does not seem to recognize the V2 device. Is there some driver or something I can load/update so the Dfuse tool can be used? I really don't like having multiple tools to do the same job and I use the NanoVNA Saver as I personally like it better than the QT tool.

Thanks for reading!

Why are you so impudent?

Are you sure you mean impudent?

I meant no offense and I don't know why one would take it that way. I asked a simple question to which I expected to get a simple answer. I don't mean to start a flame war over VNA QT verses NanoVNA Saver.

I just issued my own observation and opinion that for me the NanoVNA Saver tool is more to my liking and if there are standard tools for firmware updating I was wondering why the same tools could not be used for multiple DFU supported devices. That would make it easier for porting the tools when one has more than one PC or laptop that is used to support the device.
