Power saving modes

Introduction

The Avisaro Modules supports three power saving modes, one for the main controller and two for WLAN unit. All of them can be combined.

Putting the main controller asleep

Send a SLEEP command over the I/O interface to freeze the MCU so that it consumes very little power. The sleep can be time-controlled, this means the MCU awakes after a specific time, or it can sleep forever until it detects a pulse on its wakeup-pin. Please look here for further information.

Switching the WLAN unit off and on

Send WLAN SLEEP NOW over the I/O interface to switch the WLAN unit off. If can later be switched on again by the WLAN AWAKE NOW command. Please look here for further information.

Running WLAN in power save mode

The WLAN unit is able to save energy while being fully functional. To bring the WLAN into power save mode, use either the WLAN command (see here), or activate the checkbox on the web page.
