| Mar 21 at 19:22 | comment | added | timemage | I don't understand the distinction you're making between "powered on for the first time" and "power off and on again". If booting after having been powered off isn't what you mean by "the first time" then, what does the that actually mean? Or is there not a distinction between these? | |

| Mar 21 at 10:22 | comment | added | 6v6gt | This is for an ESP32 but the situation is the same for the ESP8266 where the enable (EN) pin is broken out: reddit.com/r/esp32/comments/ou6r8d/… The idea is to delay enabling the device for a few milliseconds after power is applied to it to help ensure the power is stable. But also add some details of the power supply to your question. | |
