sleep() [ Classic API ]

SleepResult class

Since 0.8.0:

This class allows to query the information about the most recent System.sleep(). It is only recommended for use in Device OS 0.8.0 - 1.4.4. There is a newer, more flexible class SystemSleepResult in 1.5.0 and later.

reason()

// SYNTAX
SleepResult result = System.sleepResult();
int reason = result.reason();

Get the wake up reason.

// EXAMPLE
SleepResult result = System.sleepResult();
switch (result.reason()) {
  case WAKEUP_REASON_NONE: {
    Log.info("did not wake up from sleep");
    break;
  }
  case WAKEUP_REASON_PIN: {
    Log.info("was woken up by a pin");
    break;
  }
  case WAKEUP_REASON_RTC: {
    Log.info("was woken up by the RTC (after a specified number of seconds)");
    break;
  }
  case WAKEUP_REASON_PIN_OR_RTC: {
    Log.info("was woken up by either a pin or the RTC (after a specified number of seconds)");
    break;
  }
}

Returns a code describing a reason the device woke up from sleep. The following reasons are defined:

• WAKEUP_REASON_NONE: did not wake up from sleep
• WAKEUP_REASON_PIN: was woken up by an edge signal to a pin
• WAKEUP_REASON_RTC: was woken up by the RTC (after a specified number of seconds)
• WAKEUP_REASON_PIN_OR_RTC: was woken up either by an edge signal to a pin or by the RTC (after a specified number of seconds)

wokenUpByPin()

// SYNTAX
SleepResult result = System.sleepResult();
bool r = result.wokenUpByPin();

// EXAMPLE
SleepResult result = System.sleepResult();
if (result.wokenUpByPin()) {
  Log.info("was woken up by a pin");
}

Returns true when the device was woken up by a pin.

wokenUpByRtc()

Returns true when the device was woken up by the RTC (after a specified number of seconds).

// SYNTAX
SleepResult result = System.sleepResult();
bool r = result.wokenUpByRtc();

// EXAMPLE
SleepResult result = System.sleepResult();
if (result.wokenUpByRtc()) {
  Log.info("was woken up by the RTC (after a specified number of seconds)");
}

rtc()

An alias to wokenUpByRtc().

pin()

// SYNTAX
SleepResult result = System.sleepResult();
pin_t pin = result.pin();

// EXAMPLE
SleepResult result = System.sleepResult();
pin_t pin = result.pin();
if (result.wokenUpByPin()) {
  Log.info("was woken up by the pin number %d", pin);
}

Returns: the number of the pin that woke the device.

error()

Get the error code of the latest sleep.

// SYNTAX
SleepResult result = System.sleepResult();
int err = result.error();

Returns: SYSTEM_ERROR_NONE (0) when there was no error during latest sleep or a non-zero error code.
