MEITRACK P88L GPS Personal Tracker User Guide

Note:

1. The heartbeat packet positioning mode is enabled after users set the super deep sleep

mode and heartbeat packet wakeup positioning time. The minimum heartbeat packet

reporting interval can be set to 10 minutes.

2. In this mode, heartbeat packets may be delayed. After the device is woken up, you need

to enable the GPS module first, and then a heartbeat packet can be sent. If the GPS

positioning time exceeds the preset heartbeat wakeup positioning time and the GPS is still

invalid, an invalid heartbeat packet will be sent. If the GPS is valid, a valid heartbeat packet

will be sent. Therefore, the heartbeat packet reporting interval will be affected by GPS

positioning time.

3. In sleep mode, the device can be woken up by pressing any button of the device instead of

SMS messages or calls.

2.3.13 Smart Working Mode

In the smart working mode, the working mode of the device is determined according to users'

habits, including the settings of GPS or WiFi frequent stop places and the data tracking time

interval.

1. If frequent stop places are set, when the device enters a frequent stop place, it stops data

uploading and determines that the trip ends. Then the scheduled tracking event is disabled.

When the device leaves the frequent stop place or the SOS button is triggered, the device

determines that the trip starts. Then the scheduled tracking event is enabled. If no frequent stop

places are set, no trip ending events will be generated.

2. When the data tracking time interval is less than or equal to five minutes, the GPS module

always works. When the data tracking time interval is greater than five minutes, the GPS module

may work or not. In this way, the device will determine whether it continues to work or enters

the sleep mode based on users' behaviors, so as to save battery power. But the condition is that

this action cannot affect the device's travel routes. After the smart working mode is enabled, the
