Hi
I have tested this "random nerd" code, it wakes up but I need to know witch button was pressed to make if sentences do different jobs according to button pressed.
Any tip to make code reply with witch button pressed?
Code is for 1 of 3 buttons, gpio34
Serial print gives
>GPIO that triggered the wake up: GPIO inf
Witch is not what I expected
Schematic:
Testing 34:

Deep Sleep with External Wake Up
=====================================
This code displays how to use deep sleep with
an external trigger as a wake up source and how
to store data in RTC memory to use it over reboots
This code is under Public Domain License.
Hardware Connections
======================
Push Button to GPIO 34 pulled up with a 10K Ohm resistor
NOTE:
======
Only RTC IO can be used as a source for external wake
source. They are pins: 0,2,4,12-15,25-27,32-39.

First we configure the wake up source
We set our ESP32 to wake up for an external trigger.
There are two types for ESP32, ext0 and ext1 .
ext0 uses RTC_IO to wakeup thus requires RTC peripherals
to be on while ext1 uses RTC Controller so doesnt need
peripherals to be powered on.
Note that using internal pullups/pulldowns also requires
RTC peripherals to be turned on.
