GL100 @Track Air Interface Protocol
4.8. Over Speed Alarm
The backend server can set a speed threshold for the terminal. The terminal will report its position
and speed to the backend server when its moving speed is over this threshold. The setting of over
speed alarm is done by the
AT+GTRTO
command.
Please note that the terminal will check the speed every time after successful GPS fixing.
Example:
Enable “over speed alarm”:
AT+GTRTO=gl100,
9
,
1
,
10
,20090101000000
This command will enable “over speed alarm” and the speed threshold is 10km/h.
