!POWERWAKE
Configure ULPS (ULPM/PSM) wakeup sources
Configure the wakeup sources (triggers) for Ultra-low Power State (Ultra-Low Power Mode
(ULPM) and Power Saving Mode (PSM)).
Note: WPx5xx supports only ULPM, not PSM.
When a module is in ULPS, the module is almost completely powered off (Note: In PSM the
module is in a network-aware state. The module’s low state is registered on the network and
sleep time is negotiated.). When a configured trigger is detected (e.g. when the trigger meets
the <above> and <below> conditions), the module boots.
Note: Use <above> and <below> as follows:
• To set a trigger condition inside a range (e.g. trigger in the range 0.5 to 1.0V),
set <below> > <above> (e.g. trigger: <above> 0.5V and <below> 1.0V)
• To set a trigger condition outside a range (e.g. trigger outside the range 0.5 to 1.0V),
set <below> < <above> (e.g. trigger: <below> 0.5V and <above> 1.0V)
After configuring wakeup triggers, the command AT!POWERMODE can be used to enter
ULPM or PSM.
Password required:
No
Notes:
•
Timer must be configured for PSM mode.
•
At least one wakeup source must be configured before !POWERMODE can be used to
select a power saving mode option that requires wakeup sources.
Usage:
•
Execution (clear) (WP76xx/WP77xx only):
AT!POWERWAKE=<clear>
Response:
OK
Purpose:
Clear all wakeup sources.
•
Execution (timer):
WPx5xx:
AT!POWERWAKE=<type=1>,<timeout>
WP76xx/WP77xx:
AT!POWERWAKE=<type=1>,<timeout>,[<active_time>,[sync>]]
Response:
OK
Purpose:
Set the timeout period for a wakeup timer.
•
Execution (GPIO):
AT!POWERWAKE=<type=2>,<gpio>,<edge>
Response:
OK
Purpose:
Configure a GPIO as a wakeup source.
•
Execution (ADC):
AT!POWERWAKE=<type=3>,<adc>, <above>, <below>, <interval>
Response:
OK
Purpose:
Configure an ADC as a wakeup source.
