Anyone member can add a new Wiki page and/or edit existing ones,
so that is probably the easiest way to implement a document modifiable by others.
So far as I know, Groups.io has no specific FAQ mechanism.

I see that both eddy555 and hugen have recently released new versions of their respective firmware.
My nanovna is the -H model, 2.8", HW version 3.3
Can I indifferently load one or the other of those firmware, or just a specific one ? Currently I have the 0.5.4 by hugen, compiled on December 9,

Second question : before I played with it, my nanovna at power on did show a splash screen with some version info.
After some time, and a lot of recalibrations, at power on it goes directly to the graph screen, no splash screen anymore.
Is it caused by some mine wrong actions, or should I be worried ?

see post #9737 for a workaround.

HTH

Error during the update caused problems:
- Screen completely white and without commands;
- Does not connect to the PC (COM port);
- Does not access DFU mode (jumper);
- It does not appear in the device manager list.
Any suggestions on how to access the nano?
Thanks!! 73 !!

Judging by a number of recent posts, a lot of folk are now having problems installing nanovna-saver on Debian based linux.

I've identified the problem, and have written some notes on how to fix it.

I'd like to share this with the group. Please could you gentlemen advise as to how best to do that. pdf in Files section, wiki, or even FAQ?

I tried just running the program as suggested in post #9840. Tried everything so far that been suggested. I do have it running in windows 7, but I just despise windows.
This is what I am seeing at this point.

Hi-

I've spent three interesting days updating my EeePC notebook PC's Debian Linux OS so I could install the nanovna-saver software. Finally got there and all was good until I decided to load a calibration file and/or create a new one.

I've found that the calibration panel doesn't fit the screen. The bottom third or so is not visible, so I don't have access to the buttons for loading and saving calibration data. I hoped that I could drag the panel upward, but I cannot - I can move it down only, or stretch it horizontally, which is no help.

I did a few generic Debian/gnome searches on the issue and it seems to be not uncommon, but the solutions offered don't seem to help in my case.

Anyone got a suggestion for this? If there's no resolution, perhaps the author would consider changing the layout of the panel to accommodate screens with limited vertical space(?)

Thanks,

Nick, WA5BDU

Hi Dennis,

I think the solution is written here:
/g/nanovna-users/topic/51160730

if not, use and read the wiki description
it seems to me that for the first time the lack of a driver between the computer and nano is the source of the problem.

Hi All, had my VNA-H for a short while and decided it was time to update it, mine is board V3.3, firmware 0.2.3.2, using DFUse, I put my unit into DFU mode and uploaded the latest upgrade. As i have the DFU option in my config, i assume i did not need to short the 2 pins together, that said, the software showed success at every stage, but my device is still stuck on its original firmware, help please.

Bob,
have you tried running the software, rather than the install procedure? The
install pulls in the dependencies - if you already have them installed, you
can just run the program instead.

('python3.7 nanovna-saver.py' should work)

Currently I have owner read and write permission on both /.cache and /.cache/pip but only group read and write permission on /.cache/pip.
Anyway I have NanoVNA-saver running through Nick's requirements.txt hack so will leave alone

den@den-ThinkPad-T520 ~ $ ls -dl /home/den/.cache
drwx------ 36 den den 4096 Dec 9 19:08 /home/den/.cache
den@den-ThinkPad-T520 ~ $ ls -dl /home/den/.cache/pip
drwxrwx--- 5 den den 4096 Jan 15 22:23 /home/den/.cache/pip

Thanks for the suggestion

I have the above tablet and wonder if anyone has been able to run their
HF+ from one? If so, what did it take to enable it?

=====================================

Ray, I expect you meant to post to: /g/airspy. I don't see why it shouldn't work from /any/ Windows tablet as there are no extra drivers required.

I've ran into issues too with Ubuntu 18.04.3 LTS

All of the dependencies are present. Below is the results of the install.

I've tried creating the tmp folder and manually moving setup.py . It really didn't make much difference.

If any other information would be helpful, let me know.
