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

Antonio,

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.

Hi Dick, I want to order but your website only says contact me with no link? Please provide a link or an email address please.

Hi Dick

do you have any PCBs available?

Best regards,

Malcolm

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.

My firmware is synced to DiSlord Nov 30th version, I will update to the latest version after doing some testing.

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

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!

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)

Sync DiSlord version 1.1 was just released. NanoVNA-Server now connects.

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).


Roger

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

actually, search for "SD CARD SLOT"

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

First of all, thank you DiSLord for the responses, and I echo the many other comments in this forum about the most excellent support you continue to provide!

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?
