Environment

  • Development Kit: esp32-c3-devkitm-1
  • Module or chip used: ESP32-C3
  • IDF version (run git describe --tags to find it): 4.4.1
  • Compiler version (run xtensa-esp32-elf-gcc --version to find it): 8.4.0+2021r2-patch3

Problem Description

ESP32-C3 wakes up from deep sleep by using a GPIO. esp_sleep_get_wakeup_cause returns 7 which stands for ESP_SLEEP_WAKEUP_GPIO which is documented as "light sleep only".

Is this a documentation issue or is this the wrong wakeup cause?

Hi,

You are right, the docs are wrong here. C3/C2 do support ESP_SLEEP_WAKEUP_GPIO from deep sleep (see SOC_GPIO_SUPPORT_DEEPSLEEP_WAKEUP)

I'll update the docs to reflect this.

ESP_SLEEP_WAKEUP_GPIO is also a valid deep sleep wakeup cause on targets
