I have seen an option for the esp8268 called early_pin_init = false. I can't find a similar thing for the ESP32 - S3 - wroom module. I have a board where the internal pull up is enough to turn on the transistor that drives a relay causing it to pulse on multiple times during ...

Tested it for all GPIOs that can be a DI. Works for all of them but not for GPIO34 ... GPIO39. They work as input but get not pulled up. Same with INPUT_PULLDOWN. These input-only pins don't have PU/PD circuits. OK, thanks for the information. ...
The idea is that at first ESP32 goes through some UDP broadcasting - IP recognition (with server) handshake algorithm, then establishes the TCP connection and starts to constantly sample GPIO states (the ESP32 reads whole GPIO state registers and sends that information via TCP to the server. ...
The push button can be interfaced with ESP32 either through a pull-up resistor or a pull-down resistor. In Pull up resistor mode, when the push button is not pressed, input to the GPIO pin will be logic high or vice versa. In pull-down resistor mode, when the push button is pressed...
