Re: My NanoVNA is not recognised by DFUse when using V 0.2.3 firmware

 

Just a thought...
Have you tried doing the link on the nano vna to pop it into boot mode???
Re: firmware edy 555 in dfu extension

 

Thanks Oristo ! I succeeded now with your info. Dean thx too !

Re: firmware edy 555 in dfu extension

 

you need dfu file manager, that should have unpacked with DfuSe 3.06 software.
This will covert the hex file into the .DFU you require
Re: firmware edy 555 in dfu extension

 

Hi Hans

Can i find anywhere the firmware from edy555 in .dfu extension ?
No

I use DfuSe v3.0.6 that's is flashing with files with dfu extension
In /g/nanovna-users/wiki you will find
/g/nanovna-users/files/Firmware/Windows%20guide%20on%20how%20to%20write%20firmware.pdf

.. which describes how to convert to dfu, using DFU File Manager,
which came in the package with DfuSe Demo.
firmware edy 555 in dfu extension

 

Hello all,

I looked at github for new firmware 0.4.0 and i found at only the firmware in hex or bin.
Can i find anywhere the firmware from edy555 in .dfu extension ? I use DfuSe v3.0.6 that's is flashing with files with dfu extension.
Thanks in advance,

Hans

Re: DL9CAT version 0.4.0-2? I have encountered the following problem. CW FREQ once started can not be stopped,you have to shut down the device.

Greetings DL9CAT,
I have loaded reald 0.4.0-2 and tested; the C0/C1 reverse text colors for selected trace works fine; I can now see which trace is selected before changing trace parameters.
I will also note that your vbat offset works well for the 1N4148 diode I installed; it indicates full for most of the cycle, then 2/3, 1/3, and when it turns red there are only a few minutes before it shuts down. So it does what it should! :)
Also, noted that the "Ch-0 Info" screen works even if all traces are off (reduces clutter) and freq is CW, so it works like a text-based antenna analyzer and is very easy to read, with those 5mm high digits! And with only SWR trace on, and a small span, the jog switch will move the frequency in small steps, and Marker > Search > Minimum will find lowest SWR point in the swept span.
I'm sure these added features will make the nano more attractive to hams with primary interest being antenna analyzer.
Thanks again,

Re: My NanoVNA is not recognised by DFUse when using V 0.2.3 firmware

 

Well, the PC regognises the device as "STM32 Bootloader" , is that not OK?

I have loaded several versions of version into my NanoVNA before, without any problem.

Thanks anyhow

Hi Rune,

Yes, I used Zadig to install the USB drivers like WinUSB for use with SDR hardware? (Software Defined Radio).

Besides, the PC recognises NanoVNA, you hear the sound when connecting and the device manager reports " USB Device STM32 bootloader" .

Thanks for you rerply

Re: 1500Mhz, usable ?

 

Hi Andy,
upgrading to a higher frequency range doesn't lose you any other features,
and you don't *have* to use it ;-) But the newer firmwares DO contain
bugfixes, and new features. QRP RX has been very active in fixing errors
and improving the readings of the NanoVNA. So even if you won't use it at
1500MHz, do consider upgrading. :-)

I'm not exactly seeing overwhelming evidence that I should upgrade to a

I'd probably be better off with an old GDO and a field strength meter up
there ;-)

Ok, I stand corrected, Nooelec is the ttrftech authorized distributor. I hadn't look at edy555' GitHub page in a while.

Re: Any plans to publish the NanoVNA board files

 

I don't know where you got your info from but ttrftech's edy555 was the original designer of the NanoVNA and hugen modified the charging circuit and designed the current PCB and was selling them on taobao.?
Nooelec is NOT the official seller, hugen is through his taobao site and on a site on AliExpress. As far as hugen is concerned, Nooelec is selling clones of his design.?
If you're looking for board files, look at the ttrftech GitHub repo. If you ask hugen nicely, he might share his redesigned PCB with you. The biggest area to be concerned with in the design is around the port 1 and 2 bridge circuits and the mixer.?

Re: Reply to Rune

 

Vaclav,
it sounds like you have the background for it then, but maybe just not
recent experience! The error you got concerning C99/C11 should be fairly
self-explanatory, and probably just depends on what compiler you are using
- setting the right options in the Makefile should clear it. :-)

Good luck!

Hello,
I found your idea of adding Bluetooth interesting, but I am a little
confused: Are you normally a C-programmer? Do you work with embedded
software? The firmware is written in C, and I probably wouldn't recommend a
project like this as a first go - it would take at least some experience
:-)

Rune,
here is SOME of my background.

I wrote my first (professional ) program in 1972 , in an assembly.
The task was to set-up a path thru long distance telephone switch and test
it for continuity.
I "switched" to C language and wrote another (paid for) program passing
data thru similar network - somewhere around 1980ish.

I am happy retired and as form of punishment I write C/C++ code - for fun.
I "did" Arduino and ditched the "kindergarten educational toy" after few
years.
I have several project "work in (slow) progress" using Raspberry Pi 3 ,
I did tried Raspberry Zero and ditched that - it did not yield to remote
programming .
I am still working on my own version of VNA , got the hardware about 75%
wired , and got stuck on adding Bluetooth to that hardware.
So I decided to use NanoVNA to do the Bluetooth addition there.
No, I am not doing all this for money , just a hobby.
Cheers
Vaclav AA7EJ
