System.sleep (SLEEP_MODE_DEEP, longSeconds) makes no mention of waking up on external interrupts #423
Description
The documentation on System.sleep (SLEEP_MODE_DEEP, longSeconds) says "the device will automatically wake up and reestablish the Wi-Fi connection after the specified number of seconds".
In fact, the device also wakes up on external interrupts while in SLEEP_MODE_DEEP. The documentation should mention this, especially as it appears that there is no API for deep sleep purely on a timer, ignoring external interrupts.
