Please explain more about voltage supervisors I will research about that.

I found the problem, as you said thats a circuit problem not a code erasing. When battery voltage is not enough to supply voltage regulator, the ESP not not powered on and pwm pins of led driver becomes floating positon and gives as much power as they can to leds, so i have one more question that pr...

I dont look serial values, but i think thats not a battery issue because my schematic based on AL8805 led drivers and when no pwm signal is enter the driver leds lights at maximum, and when 'erased status' occurs, leds running on maximum value, i think that no pwm means that no active esp. Because m...

Not works like as expected. Even onboard led not works. After reuploading code, it works again.

I have Esp32 based pcb, some leds, drivers, 18650 battery etc. I just simply control the leds with esp but i have flash(code) erase problems, when i leave the esp at ON for example 7-8 hours, the code in the board are deleted, but i dont know the reason. Please help me, i attached the whole schemati...
