Just to see what user think is the best currently available firmware. I use the device to process data via Python because the first one I received had a faulty screen (strap was actually not soldered

This is indeed how I started...

I use the main page to quickly find links to even my own pages. FWIW, I expect (and try to help) Wiki main page to be mostly up-to-date, but necessarily brief. Other pages and links are for more

Looks like this was a scam after all. The negative feedback is now pouring in with buyers complaining of fake tracking numbers and never receiving the product. "If it is too good to be true...."

I didn't know why you liked the BAV99 until I just looked them up. Nice! Puzzled because the BAV99 data sheet says VF=0.7V max @ 1mA, and we are well below that...so I'd expect much less than 0,7V

Carlos, The 400mAh batteries that came with my two units have charge controllers built into the battery packs. Most certainly if you use a battery pack without a charge controller it will overcharge

Hmm, that wants updating. Latest versions should be linked in Wiki main page /g/nanovna-users/wiki

IZ5GVP, Go to this link https://oristopo.github.io/nVhelp/html/software.htm#firm for a list of NanoVNA programs that will allow you to plot and save return loss, VSWR and impedance data for your dummy

If you already have Python installed, then this script lets you send commands to nanoVNA and capture data directly to files from your cmd.exe or bash terminal window, without a separate serial console

Hi Maurizio - First send 'pause', then use 'scan'

According to the datasheet, the IP5303 charging current is 1.0A. I think the "adaptive charging current control, excellent adapter compatibility" refers to the capability of lowering output current if

That could work, but no pads on the pcb for the second resistor, and not sure if NanoVNA-Q-0.4.3 will allow sufficient vbat_offset, so I'll stick with the "BAV99 2 diode solution" for now. Life too

With BAV99 2 diodes and a fully charged battery set vbat_offset to 1000 and VBAT reads 4210mV on Version screen. Very nice - thank you very much :) After flashing and restarting the nvna I did

Thanks for your reply, However I am not trying to upload to the vna, I am trying to download the existing firmware for backup. The dfu-util man page says:- " -t, --transfer-size SIZE Specify the

Same for me Pedja, Tried on a virtual windows 7 machine (on my MAC) Gave up after a half an hour, and then tried on an old laptop, and everything is now ok. But when I tried again on the Virtual

I had the same issue and installing drivers did not help. Windows did not recognize device in manner that did not allow it to link it with drivers at all. However, device was properly recognized on

I have a lot of dummy load and i would make a graph to compare the return loss of all. With my older miniVNA i can get the data for each one because with VNAJ i can get out directly the return loss

Yes, you need to install the driver first. You can read the wiki for more help. Note that dfu-util and DfuSe Demo use different drivers. hugen
