Photon power consumption clarification

I just wanted to clarify. Does sleep on the data sheet refer to the sleep system call or some other sleep mode?

The sleep current on the data sheet is far below that of the Wi-Fi off current but the sleep system call appears to simply turn off the WiFi. My question is what is the sleep mode referred to on the data sheet?

There are multiple “sleep” modes, not only the WiFi-off one.

Sleep Current will probably refer to so called Stop Mode (STM32 jargon) sleep which puts the µC in low power mode and the WiFi module off.

System.sleep(pin, triggerEdge);
// or
System.sleep(pin, triggerEdge, timeout);
