WiFi

off()

// EXAMPLE:
Particle.disconnect();
WiFi.off();

WiFi.off() turns off the Wi-Fi module. Useful for saving power, since most of the power draw of the device is the Wi-Fi module.

You must call Particle.disconnect() before turning off the Wi-Fi manually, otherwise the cloud connection may turn it back on again.

This should only be used with SYSTEM_MODE(SEMI_AUTOMATIC) (or MANUAL) as the cloud connection and Wi-Fi are managed by Device OS in AUTOMATIC mode.
