RTC Pins Exposed for Deep Sleep Wake?
-
Are any of the ESP32 RTC Pins exposed that I can use to wake the Core2 AWS?
I can't figure out which pins could be used to wake from a Deep Sleep.

I found my answer. Looks like I can use either pins 35 or 36. Considering that I have comms on those two pins, 36 is the RX pin, so I can just toggle the RX input to wake the Core2 from Deep Sleep.

For Core2 AWS Deep Sleep Wake:
The M5Stack Core2 AWS exposes ESP32 RTC GPIOs GPIO36 (VP), GPIO39 (VN), GPIO34, GPIO35, GPIO25, GPIO26, GPIO27, and GPIO32 for external wakeup triggers. Configure via esp_sleep_enable_ext0_wakeup() or esp_sleep_enable_ext1_wakeup(). Check the Core2 pinout to avoid conflicts with built-in peripherals.Note: Some pins may require pull-up/down resistors. Test with low-power triggers (e.g., buttons) to verify wakeup reliability.
