MEITRACK T622 GPRS Protocol

Description
Set the automatic smart sleep mode when the tracker is idle.
Sleep level = 0: function disabled (default).
Sleep level = 1: normal sleep. The GSM module always works, and the GPS module
occasionally enters the sleep mode. The tracker works 25% longer in the normal sleep
mode than that in the normal working mode. This mode is not recommended for short
interval tracking; this will affect the route precision.
Sleep level = 2: deep sleep. If no event is triggered after five minutes, the GPS module
will stop working and the GSM module will enter sleep mode. Once an event is
triggered, the GPS and GSM modules will be woken up. A heartbeat event will be
triggered only in the deep sleep mode, which will be uploaded every one hour by
default.
Triggering events include: SOS alert, low internal/external battery, external power
status, GPS antenna cutoff alert, towing alert, high temperature, low temperature, fuel
theft, vehicle theft, ACC ON, (button) changes on any input port, vibration, incoming
call, SMS receiving, call, and heartbeat event (The GPS is disabled during heartbeat
wakeup.).
