+WWAKE
Query Wakeup Event
Return a mask indicating the event(s) that have pulsed the Ring Indicator (RI) signal since the
module was powered on or since the last time this command was successfully issued,
whichever is most recent.
When the command is successfully issued:
•
the mask is cleared and,
•
the RI signal is de-asserted (if it is still being asserted when the command is issued)
Usage recommendations:
•
The application should poll the module immediately upon starting up to determine the
event that triggered the RI. Some events depend upon external resources (for example,
the network) and may terminate if not handled immediately. For example, if an incoming
voice call is not handled in a timely manner, the network will reroute the call to voicemail.
•
The host application should issue this command immediately before powering down if the
intention is to leave the device powered on. This resets the wakeup reason, and no "old"
events are indicated when in fact they did not happen during the time the host application
was powered down. This is necessary because the wakeup reason can be set, and the RI
pin asserted during normal execution when the host application is powered on.
Notes:
•
Notification of losing or finding service implies that the module first had service, and then
the service changed the triggering the event.
•
If an established call is dropped after the notification of an incoming call, the module does
not reflect the dropped call in the wakeup status. The dropped call should be handled like
a dropped call in the case where the application was monitoring the device all along.
