[BUG] NUC-UPS write dumped settings breaks the settings

[RafaelKa]

After running
openups -t nucups -o NUCUPS_SETTINGS

the file ("NUCUPS_SETTINGS") contains:

NUC_UPS_MODE=0

Then after changing some values and write the stuff back to the UPS
and its rebooting, the values of settings are broken and following nonsense is happen:

Why there are no protective validators for settings/options?
Why there is no option or command for "factory reset"
Is this device reliable and safe to operate with Li-Ion at all?

The NUC-UPS has the
Firmware Version: (null):
VerMajor: 1
VerMinor: 3

Why i need to write settings:
The device didn't charge the cells and was stucking on "State machine CHG: END ||| State machine UPS: LPWR(or similar)"
even worse it discharged the cells.
So i found the setting "VIN_MIN_STARTUP=20000"(is it set from factory?) and decided to switsch to 11.5V...
And now I have broken device?

I have the same problem!
One fix: Flashing the firmware resets all parameters and one get a "working" device.

I also want to change some values. After doing so with a changed dump file, the NUCUPS stops charging, cause it starts to measure a voltage of > 18V in "BatPack" but "BatteryOverallVolage" is around 14.7V. This seems to happen only when parameters are written. In factory mode it seems working ok. Seems that this software write in the wrong memory areas.

This software seems to be buggy. you should not use it to write parameters.

Also the Windows software has some issues it worked only at the third computer.

@frahe-ama

Also the Windows software won't work.

Try to use the zipped binaries from "Software download" Link on https://www.mini-box.com/NUC-UPS
I vas able to connect to the NUCUPS

Flashing the firmware resets all parameters and one get a "working" device.

Which firmware and how did you flashed the NUCUPS?

@nicupavel
Where to get the Version 1.3 of NUCUPS firmware?

[RafaelKa]

@nicupavel
Please prioritise this issue, because the NUCUPS device is really not usable.
Please provide the 1.3 firmware on official site.
Please provide the ability to reset the devices(not only NUCUPS) to factory reset.

Please implement the confident mechanism in firmware(ignoring all settings) to avoid deep discharge at all and specially on present DC-IN(I'm confused, why in general this happens?), because of cell blowing hazard on cells without protection circuit.

Don't disdain the Li-Ion are really dangerous on wrong usage!

Which firmware and how did you flashed the NUCUPS?

Here is the "manual" for the NUCUPS: https://wiki.mini-box.com/index.php?title=NUC-UPS#Features
On this page you will find a section with description of the firmware update. There you can also find the updater and the firmware 1.3: https://wiki.mini-box.com/index.php?title=NUC-UPS#Firmware_update

It needed three computers to get the Windows software working. I found one older device, which is possibly not on the newest updates? Don't know what the software is doing. So far it seems that the NUCUPS work as expected when configuring with Windows software.
So this Linux Software must have a big bug regarding the NUCUPS. I would not recommend it anymore for configuring the NUCUPS.
Sadly the is the issue with the Windows software not running on all Windows devices.
