< Analog Input VCC>: The value of the analog input voltage. When the voltage of the analog
input meets the alarm condition as set by command AT+GTEPS or AT+GTAIS, the device
will send the current analog input voltage with +RESP:GTEPS or +RESP:GTAIS message
to the backend server.
<Report ID/Report Type>: The report ID and the type of the report type in hex format. 4 high
bits mean report ID and 4 low bits means report type.
Report ID has different meanings in these two messages.

+RESP:GTLBC,
If the parameter <Location By Call> is set to 1 by the command AT+GTCFG, the device will get
and send the current position to the backend server by the message +RESP:GTLBC when there
is an incoming call.
Example:
+RESP:GTLBC,080100,135790246811220,,+8613800000000,1,4.3,92,70.0,121.354335,31.222
