Re: NanoVNA and PC.

 

OK, I understand but you still have not answered one question: Can you talk to your H4 through Terraterm or putty?
Please install this version of firmware for your H4:
/g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware/NanoVNA%20v1.0.69%20fw%20pack.zip
Unzip and ONLY use the _H4_ DFU file.
Verify you can talk to the command console through a terminal program on your PC before trying to use any of the Nano PC apps.

If not, you need to troubleshoot that first.
I started this topic and I said I have a Nanovna-H4. W10 64 bits
All this does not happen with the original firmware v0.5.0.
I do the tests that you tell me and I answer.
Thanks? /Antonio? EA7HJ

I have updated V1.1 the firmware, but I still can not use the software such as Nanovna, Nanovna-APP, Nanovna-Saver, Nanovna-Sharp and view the PC on-screen curves.
Can someone connect to the PC with the aforementioned software?.
The nanovna-app even update the firmware perfectly, however to see curves does not connect with the device.
I have also tested with the Zadig driver and does not connect either.
Any help about it?
Thanks in advance.

Re: Nanovna H4 very slow sweep speed?

 

Sweep speed depend from bandwidth.
You can see this setting in middle of frequency range at bottom
"bw: XXXXHz 101p"
Lower XXXXHz value - more slow sweep time

For select use DISPLAY->BANDWIDTH (default 1000Hz, more faster 4000Hz), this option stored in config, so after need save it in CONFIG->SAVE

Hugen,

Thanks for the clarification.

Try updating the firmware and if the problem is not solved, provide a photo of the main screen.


Nanovna H4 very slow sweep speed?

 

I just got a nanovna h4 off Amazon with good reviews (seller HUAIFANGPING)

It seems to sweep very slow (about 8 seconds a sweep). Every time I adjust the antenna, it takes about 8 seconds to see the trace refreshed and the SWR updated.
Is this normal for the h4 or do I have a dud? Online videos show much much faster sweep speeds on other nanovnas...

Thanks!


Re: NanoVNA and PC.

 

Does this Hugen releasae include the enhancements DiSlord released earlier today as DiSlord v1.1 beta 1?

DiSlord Update to v1.1 beta 1:
- Init i2c bus devices on low speed, change on max speed after (i hope this allow fix problem vs hang on first power on)
- 2x increase wait time for SD carf (also hope this fix errors on old slow cards)
- Add backup feature, this allow save some settings (freq range / points count / jog step / leveler mode / bandwidth / last used slot)
Backup restore settings only for stored on flash slot (not work for RAM calibration data)
By default loaded 0 slot (if no backup enabled / on error / no battery)
- Small ui changes

Divide Expert settings on 2 screens
Added Remember State (enable/disable backup feature) checkbox (need save config after for apply)

I've got an used NanoVNA-F by sysjoint.
It shows:
Version: Firmware 0.1.5
Frequency: 10k to 1,5GHz
Build time: May 17 2020
My questions are: Which version have I got and is there a new firmware out for it?
I've looked at the sysjoint.com page and downloaded the manual, but I see in
the files folder of this group that there are new firmware versions.
Thanks, Alex
Alex,

You have the latest firmware for your Sysjoint -F. Some people have tried using the -F firmware specifically made for the BH5HNU NanoVNA-F but issues have been reported. Attached is a discussion on the topic from Facebook NanoVNA-F group with comments by BH5HNU (Leon Huang).

What you got is already the latest version listed on their website:

I opened the case on my H4 VNA and found the silk screen outline for the card slot, but in my case the connector is not populated.? The good news is I have sufficient skills to solder one in.? The bad news is I don¡¯t know what part to order..

Gary, if you have a link, please post it??

This has been discussed in the forum messages a number of times - search for sdcard socket or sdcard slot
