Tail Character 1 $ $
 <Analog Input VCC>: The value of the analog input voltage. If using command AT+GTAIS
to set the device report the analog input voltage periodically with fixed report, the device will
send the current analog input voltage along with +RESP:GTFRI message to the backend
server. If not set, this field will be reserved.
 <Report ID/Report Type>: The report ID has no meaning in +RESP:GTFRI and it is always
0.
Report ID has four meanings as below.
1: fixed timing report.
2: fixed distance report.
3: fixed mileage report.
4: fixed timing and mileage report.Report type has two meanings as below.
0: the normal fixed report.
1: corner report which indicates that the device just turns around a corner.
 <Number>: The number of the GPS position included in the report message. In the message
+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:GTAIS,
If the analog input alarm is enabled by the command AT+GTAIS, the device will send the
message +RESP:GTAIS to the backend server when analog input voltage enters the alarm range.
