Function esp_idf_svc::hal::sys::esp_deep_sleep_try

pub unsafe extern "C" fn esp_deep_sleep_try(time_in_us: u64) -> i32

@brief Enter deep-sleep mode

The device will automatically wake up after the deep-sleep time Upon waking up, the device calls deep sleep wake stub, and then proceeds to load application.

Call to this function is equivalent to a call to esp_deep_sleep_enable_timer_wakeup followed by a call to esp_deep_sleep_start.

@note In general, the function does not return, but if the sleep is rejected, then it returns from it.

The reason for the rejection can be such as a short sleep time.

@param time_in_us deep-sleep time, unit: microsecond

@return

• No return - If the sleep is not rejected.
• ESP_ERR_SLEEP_REJECT sleep request is rejected(wakeup source set before the sleep request)
