(1) Upload by interval
The default upload interval is 20 seconds, which means every 20 seconds the

sending SMS command: TIMER,T1,T2# (5≤T≤18000 seconds)
e.g. TIMER,20,30#
It means when ACC is on, GPS data upload interval is 20 seconds; when ACC is
off, GPS data upload interval is 30 seconds.
(2) Upload by distance
Send SMS command: DISTANCE,D# (100≤D≤10000 meters)
e.g. DISTANCE,300#
It means for every 300 meters, the terminal will upload GPS data to platform.
NOTE: if the upload interval is short, the GPRS current will add up. Please set
the suitable upload interval.
