Brown Out reset
Posted: Fri Apr 06, 2018 7:24 am
I am encountering an issue with ESP32 hardware brownout detection and reset.
Scenario: i have some bulk capacitors on the 3.3V power supplies to be able to send out "I am dying" message while power is going away.
if the board gets powered back, before the capacitor gets fully powered down ( 1.4V ), the ESP32 doesn't reboot.
is there a way to set the ESP32 to shutdown before it is unsafe to operate or this is a bug?
