Hi Nigel,
I don't think NanoVNA-Saver ever outputs (from its own code) a message with
the text "unable to find" anything. So it might be from a module or
something.
Could you start the software with "-D logfile.txt" as a command line
option, and send me the log file? This should show any errors. You can send
direct to mihtjel@..., or here.
Thanks for trying the software :-)

Am enjoying the journey learning how to use the nanovna but have
encountered a problem relating to using nanovna saver that requires
guidance from those more knowledgeable than I am regarding interfacing the
device to a Windows 7 notebook.
I have connected the nanonvna to the same notebook to upgrade the device
firmware (Release 0.1.1 with added scan command and battery.dfu) using
dfuSe_Demo_3.0.6 with no issues.
Trying the 'original' P.C. application (Nanovna-Sharp) I can establish a
connection of sorts (able to change Connect - Disconnect indication but
that is all) if using COM3 (Com1 is the only other port shown and if
selected then unable to connect/disconnect) but no data transferred so
probably an anomaly.
Have installed the latest Nanovna-Saver (along with Python) and after
start up and GUI displayed, an error in the command / DOS window (behind
the GUI) shows as "unable to find..." - am guessing that the blank between
' ' is looking for the Com port and performing a scan shows no device or
port available.
Checking the Windows device driver properties shows nanovna to be using
ChibOS/RT Virtual Com port and Windows recognizes device being attached /
removed.
Booting the same notebook into Linux (Puppy) the result of a 'lsusb' shows
the nanovna as connected. As an aside, I considered trying to build
nanovna-saver on the Puppy system but too many dependencies and not good
experience in the past with other applications (I am not really a software
person).
Searching for similar posts I only see Windows 10 issues and perhaps I
have missed the answer to this challenge so apologies in advance.
Sincerely hope is an easy fix and that biggest issue is my ignorance... an
idiots 'how to' (step by step) guide is probably needed.
MANY thanks for any guidance / suggestions.
