Feature request: Screen OFF serial command

[DiSlord]

Made some test on my nanoVNA H4 power usage:
Set Power 2ma (for constant generator power usage)
Now set backlight value (config->brighntess):
brighntess 100% 0.367mA
brighntess 50% 0.312mA
brighntess 0% 0.253mA

Next I set backlight to 0 (but hardware on allow off backlight)
Additional I send LCD module off command and disable any display update
0.231 mA

As can see most good just set brighntess to 0%

Most power usage on V2 - ADF4350 or MAX2870 generators, LCD display module need ~20mA power + power for backlight (you can set to 0 in config for minimise power usage)

If you set sweep range to SI5351 range ( < 140MHz) then V2 disable ADF4350 / MAX2870 generators

Thanks for your reply,
Please excuse this question, but use of your firmware for V2 is recommended, but it seems you do not maintain V2 version?
Does this NVNA-D F/W work with V2?

My variantV2 firmware not open
Better say my variant for LiteVNA firmware not open, privided by me V2 firmware based on LiteVNA code, nanoVNA-D for H / H4 also use parts of LiteVNA code (and open)
