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.

Problem trying to update firmware

Francesco 2022/01/17 03:15

Is frustrating to get problems with firmware with the V2plus4  I don't get the opportunity to load the calibration standard feature to have better calibration.
The device became less util for this firmware issue.
I hope the team from Nanoforte resolve this problem a soon as possible.

For our information, what firmware number is creating the calibration

Neither of the 2 windows software GUIs show any place to upgrade the firmware. The manual is very poorly written for this, maybe you have to use the linux version to update?

*I continue with the impossibility to upgrade the firmware on my device, the bootloader is blocked to close the possibility to use different firmware, this reduces the possibility to get better use of theV2 plus4.
Please provide the possibility to open the boot-loader to use different firmware.* *This personal dispute go to damage the owner of NanoVNA v.2plus4 buyer and in the end, go to damage the seller,*

Clones complicate everything, however, NanoQT software was (in my experience) the easy way to update firmware.  Good luck !

V2plus4 is not a clone
