@Puneit-Thukral Thanks. I am not quite sure, so correct me please if I am wrong, but I think I am already using the MiniCore bootloader with platformIO. Or do I need to configure to explicitly use the MiniCore bootloaders? Also I have set BOD to disabled as I read somewhere that no BOD can also save battery.
I'm not sure, but I believe I'm already using the MiniCore bootloader with platformIO. Please tell me if I'm incorrect. Is it necessary to set the MiniCore bootloaders explicitly?
