Notes
• When this command is used, it will generate event group 0 events in the
event table when the AT$EVENT? command is issued.
• The <retry period> parameter of this command populates the event timer
value when the AT$EVTIM4? command is issued. The AT$EVTIM value
will be in seconds. The parameter will also generate additional event
group 0 entries.
• If AT$EVDEL=0 is issued or any entry for group 0 is deleted, this
command MUST be re-entered for proper functionality. If a read
command is issued, it will not reflect the true state of the AT$WAKEUP
setting.
• Wakeup messages are sent to the IPs specified in AT$FRIEND and to the
port specified in AT$UDPAPI command.
