ESP8266 和 ESP32 之间使设备进入深度睡眠的推荐代码有何不同？

Question

The following code is recommended to put an ESP8266 in deep sleep for 60 seconds:

ESP.deepSleep(60 * 1000000);

I use it on the ESP32 it also works, but the recommended code for ESP32 is:

esp_sleep_enable_timer_wakeup(60 * 1000000);
esp_deep_sleep_start();

Is there a difference between the two for the ESP32?

Answer 1

With ESP.deepsleep you can't use different wakeup sources – only a timer:

void EspClass::deepSleep(uint32_t time_us)
{
    esp_deep_sleep(time_us);
}
