sleep() [ Sleep ]

STOP (SystemSleepMode)

SystemSleepMode::STOP, STOP, SystemSleepMode.STOP

// EXAMPLE
SystemSleepConfiguration config;
config.mode(SystemSleepMode::STOP)
      .gpio(WKP, RISING)
      .duration(15min);
System.sleep(config);

// EXAMPLE
SystemSleepConfiguration config;
config.mode(SystemSleepMode::STOP)
      .network(NETWORK_INTERFACE_CELLULAR)
      .flag(SystemSleepFlag::WAIT_CLOUD)
      .duration(15min);

The SystemSleepMode::STOP mode is the same as the classic stop sleep mode (pin or pin + time).

• Real-time clock (RTC) is kept running.
• Network is optionally kept running for cellular, similar to SLEEP_NETWORK_STANDBY.
• On the Argon, network can optionally be kept running for Wi-Fi.
• BLE is kept on if used as a wake-up source (Gen 3 devices only).
• UART, ADC are only kept on if used as a wake-up source.
• GPIO are kept on; OUTPUT pins retain their HIGH or LOW voltage level during sleep.
• Can wake from: Time, GPIO, analog, serial, and cellular. On Gen 3 also BLE and Wi-Fi.
• At least one wake source must be specified in STOP sleep mode.
• On wake, execution continues after the the System.sleep() command with all local and global variables intact.

Typical power consumption in STOP sleep mode, based on the wakeup source:
