Beware of cheap underperforming clones

As of 2023 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.

Error Msg connecting NanoVNA V2 plus4 to VNA QT

HB 2023/04/08 14:10

Just received a V2 Plus4 - version 20220301

Was going to update the firmware to 20220814 - so I downloaded the .BIN file.

Downloaded the cypress windows driver.

Downloaded VNA QT (ver 1.1).

Installed driver, extracted QT zip, and started the V2 PLus4 connected to Win 10 PC via USB cable.  Determined COM port number from device manager, started VNA-QT and selected correct COM port.  I receive an error message that says "Exception" and then No Error.

Rebooted everything, tried again, same error.

I downloaded VNA Saver.  It will connect and control my NanoVNA V2 Plus4.  I do not know how to update firmware with VNA Saver.

Any help?  Do I need the new firmware?

Probably another d@mn clone.

As far as i know the plus4 does not exist as a clone...

Try nanovna app... That works fine with saa2n and v2plus4...

Best frontend of the 3 available software (personal view)... If i try nanovna
qt or saver.. Or app... The last one is the best one

I couldn't get VNA QT nor Saver working at first despite installing the Cypress USB driver.  I couldn't update the firmware because QT couldn't connect.
I then tried changing the COM port # from COM10 to COM7 in device manager and was able to get VNA QT to connect.  I was then able to do a DFU, updating the firmware to the latest firmware.

To make the COM port assignment change, I first had to show hidden devices and uninstall one of the various unused devices that had previously claimed COM4-COM9.  I then went into the driver properties for the NanoVNA and changed the COM port assignment under the Port Settings tab... Advanced...

After doing this, VNA QT was able to communicate with my NanoVNA.  Still no luck with Saver, though.

Update -- I got 0.4.0 to work while 0.5.3 of Saver still will not run.
