Can ESP32 Support WFE Signal Mechanism Similar to ARM-vX Architectures for Power Saving?
Do you have an idea whether ESP32s support the WFE signal mechanism or something similar which is found in ARM-vX architectures?(To be more precise if the SOC can be woken up by an event loop)
Solution
Yes, the ESP32 supports mechanisms similar to ARM’s WFE. It uses deep sleep and light sleep modes and can wake up on events like timers or GPIO interrupts. Use the ESP-IDF API to configure sleep and wake-up behavior.
