GT300 @Track Air Interface Protocol
- 46 -
Examples:
AT+GTTRI=gt300,1000,2300,8,120,1,20,500,3,0002
— Reports from 10:00 to 23:00 every day.
— Power on GPS every 120 seconds and power off after GPS fixing finishes.
— Send fixed timing report every 8 minutes.
— Please note in this example each fixed timing report message will include 4 (8*60/120)
position records.
AT+GTTRI=gt300,1000,2300,5,30,1,20,500,3,0002
The terminal will enter “emergency mode” as the <fix interval> is less than 60 seconds, and the
GPS part will never be closed. The terminal will report the real time position every 30 seconds.
AT+GTTRI=gt300,1000,1000,5,60,1,20,500,3,0002
The terminal will report on the whole day as the <begin time> is equal to the <end time>.
AT+GTTRI=gt300,1000,2300,0,60,1,20,500,3,0002
The fixed timing report is disabled as the <send interval> is “0”.
4.3.2. Movement Detect
The “Movement Detect” function is used to temporarily disable the fixed timing report when the
terminal stays in the same place without moving for a long time in order to save the
communication cost and power consumption.
Examples:
An example is given as following:
AT+GTTRI=gt300,1000,2300,5,60,1,20,500,3,0002
<movement detect mode> = 1;
<movement speed> = 20;
<movement distance> = 500;
<movement number> = 3.
The parameter <movement detect mode> is used to enable/disable the movement detect function.
The terminal will check the movement status according to <movement speed> and <movement
distance>:
— If the distance between current position and previous is longer than <movement distance> (in
meter), the terminal will be considered as moving.
— If the speed is faster than <movement speed> (in km/h), the terminal will be considered as
moving.
The method to report is described as following:
