GV200 @Track Air Interface Protocol
TRACGV200AN003 – 110 –
+RESP:GTFRI, it probably includes one or several GPS position according to the setting of
<Send Interval> and <Check Interval>. If multi-position in one +RESP:GTFRI message, the
green part repeats.
 <Hour Meter Count>: If hour meter counter function is enabled by the command
AT+GTHMC, total hours meter counted when engine is on will be reported in this field. It is
formatted with 5 hour digits and 2 minute digits and 2 second digits and ranges from
00000:00:00– 99999:00:00. If the function is disabled, this field will be reserved.
 <Multi Analog1 VCC 1
～ 3>: The value of the multi analog input 1~3 voltage. If using
command AT+GTMAI to set the device report the multi analog input 1~3 voltage
periodically with fixed report, the device will send the current analog input 1~3 voltage along
with +RESP:GTFRI message to the backend server. If not set, this field will be reserved.
 +RESP:GTERI,
If extern report is enabled, the device will send the message +RESP:GTERI to the backend
server instead of +RESP:GTFRI.
