GV200 @Track Air Interface Protocol
TRACGV200AN003 – 85 –
3.2.30. ID authentication
The command AT+GTIDA is used to protect against unauthorized use. This is achieved through a
ID card reader for driver identification, and connecting an external relay to cut the starter or the
fuel pump. To use this command, both the ID card reader and the external relay must be connected
to the device, we suggest using the Normal Close realy which is more appropriate. When the
device reads a ID, it will report event message +RESP:GTIDA to the backend server. If the ID is
in the white list, it will be authorized until next time the ignition is off. After the ignition is off
again, the authentication will be last for a short period of time according to the setting. Within this
period, the driver can turn on the engine again without identifying himself again.
