Hello @MCU1536
assuming you are using Arduino and the M5StamPLC library then it is clear as to why the date and time are not retained. There is no code in the M5StamPLC library to enable charging the RTC backup battery.
I created a PR which enables RTC backup battery charging.
Thanks

Hi! Could you please provide us your result for us to check?

EZData 2.0 for UiFlow2 is now on maintaining, we're adding exciting new features. Stay tuned!
Using this example is fine.

Hello @RPI25
hmm, I am afraid I am out of ideas, sorry.
Edit: BTW: I now tested with both, M5Core2 (original) and M5Core2 v1.1. RGB LED on port A work with both of them.
Thanks
Felix
Hello @RPI25
ok, three RGB LEDs should definitely not draw too much power.
When you add the RGB unit did you choose port A? By default port B is selected which uses different GPIOs.
Also, just to make sure, you did connect the input side of the RGB unit to M5Core2 port A, yes.
Thanks

Hello @RPI25
how many RGB LEDs are connected to port A? The flicker could indicate that port A is overloaded if too many RGB LEDs are attached.
Also, how do you power your M5Core2? Via USB-C or battery or other?
BTW: My test was with 6 RGB LEDs.
Thanks
Felix
Hello @RPI25
hmm, I've tested M5Core2 v1.1 and RGB with firmware v2.3.7 in UIFlow 2.3.7 and it works for me. No power issue at all.
You can find my example in the UIFlow2 Project Zone: M5Core2_RGB_Test_UIFlow2.3.7
Thanks

Hi @felmue @Physalice
This issue seems to be related to any unit with a screen. Anyway, we have fixed it!
