Clean transition from automatic light sleep to deep sleep

Postby boarchuz » Fri Sep 06, 2019 8:23 pm

I'm wondering if there's a 'proper' way to do so. Without any intervention, the ESP32 will immediately wake after esp_deep_sleep_start() with reason: ESP_SLEEP_WAKEUP_TIMER (from the automatic light sleep scheduler).

I've been getting around this so far with a simple:
esp_sleep_disable_wakeup_source(ESP_SLEEP_WAKEUP_TIMER);
esp_deep_sleep_start();
This is fine for now as I don't need to use a timer wakeup from deep sleep, however I'm sure there must be a better way. Setting a new power management config with light sleep disabled has no effect.

Doesn't work?

Doesn't appear to be.
Minimal:

Code: Select all

#include "sdkconfig.h"

#include "esp_sleep.h"
#include "esp_pm.h"

void app_main()
{
    printf("Wakeup cause: %d\n", esp_sleep_get_wakeup_cause());

    esp_pm_config_esp32_t pm_config_ls_enable = {
        .max_freq_mhz = CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ,
        .min_freq_mhz = CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ,
        .light_sleep_enable = true
    };
    ESP_ERROR_CHECK(esp_pm_configure(&pm_config_ls_enable));

    vTaskDelay(5000 / portTICK_PERIOD_MS);

    esp_pm_config_esp32_t pm_config_ls_disable = {
        .max_freq_mhz = CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ,
        .min_freq_mhz = CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ,
    };
    ESP_ERROR_CHECK(esp_pm_configure(&pm_config_ls_disable));

    vTaskDelay(1000 / portTICK_PERIOD_MS);
    
    printf("Sleeping...\n");
    esp_deep_sleep_start();
}
Relevant config: (PlatformIO)

Code: Select all

#define CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ 160
#define CONFIG_FREERTOS_HZ 100
#define CONFIG_PM_ENABLE 1
#define CONFIG_FREERTOS_USE_TICKLESS_IDLE 1
#define CONFIG_FREERTOS_IDLE_TIME_BEFORE_SLEEP 2

The time spent in deep sleep correlates directly with this delay "vTaskDelay(5000 / portTICK_PERIOD_MS);", ie. in the above log, the ESP32 was in deep sleep for ~5 seconds; if I change it to "vTaskDelay(30000 / portTICK_PERIOD_MS);" the ESP32 is in deep sleep for ~30 seconds.

Ok yes I think clearing wakeup triggers before switching modes is standard like
