Hello:

I am a new user, and just received one of the recent, but not "-H" versions of the NanoVNA.
It seems to have a build date of second half 2019. No case, but shielded, and the sides are open,
with removeable backplate to see the battery and RF shields.

Is there a command, either in the PC software via USB cable, or else via the USB serial console,
that will show what version firmware I have?

Second, how can I tell if I can use the newer firmware, perhaps the H version, so that I can
get the added features such as TDR?

Sincere Thanks for helping/teaching.

I should correct my post above, since upon reading more on the wiki,
it appears to be a NanoVNA-H hardware version but without the plastic case.
It is black, USB-C, with RF shields and LiPo battery containing charge/protection
circuits on the battery.

Which versions of firmware can be used on these?

Thanks!

Neal,

Welcome to the group!

I suggest installing the NanoVNA-saver software.



IIRC it can show the firmware level. It /may/ also be displayed when you boot the device (mine doesn't).

Yours sounds like the one I have and I use edy555 firmware.

The NanoVNA-H is hugen's newest release of the NanoVNA with plastic case, battery monitoring circuit, and USB-C to USB-C resistors. The "-H" suffix was added to distinguish it from other NanoVNA's.

More recent firmware can display the version number through the menu by selecting <CONFIG-VERSION>. I believe on earlier firmware you could connect the NanoVNA to a PC and then using a terminal program type "version" to get the version number.

The various firmware available is useable with all NanoVNA and NanoVNA-H models. They cannot be used with the NanoVNA-F which is the 4.3" screen model.
