Parameter name Description Units
temp_int

The real time temperature value of the terminal. It must be noted that the
temperature
function must be enabled in the in the AT+GTTEM command, otherwise this field is empty

rx_level

The network signal strength level. The range is 0-31, and 99 is for unknown signal strength

avl_driver

The id number of the driver represented in decimal format

active_mode

Current mode of the device.
0: Power saving mode (PSM)
1: Continuous mode

battery

Current volume of the battery

%
cell_id

Cell ID (CID) is a generally unique number used to identify each base transceiver station (BTS) or sector of a BTS within a LAC if not within a GSM network

gps_acc

A numeral to indicate the GPS fix status and HDOP of the GPS position.

0 - GPS fix fails and the last known GPS position is used

1-50 - GPS fix is successful and represents the HDOP of the current GPS position

lac

Each location area has an assigned unique identifier, made up of numbers, called a "location area code" (LAC). The LAC is broadcast by each base station at regular intervals. Within a location area, each base station is assigned a distinct "cell identifier" (CI) number

mcc

Mobile country code. It is 3-digit in length and ranges from 000–999.

mnc

Mobile network code. It is 3-digit in length and ranges from 000–999.

movement_status

The movement status of the device. It must be noted that the sensor
function must, otherwise this field is empty.

0: Stillness
1: Motion

msg_type_name

The message ID of HEX format report

proto_ver

The protocol version that the terminal conforms to.

rep_type
GTGEO GTNMR GTDOG GTDIS GTAIS
0: Exit the correspondig Geo-fence 0: The state of the device changed from motion to rest 0: Reboot periodically according to the Interval and Time Settings 0: The current logical state of the input port is disabled state. 0: Outside of the predefined range
1: Enter the corresponding Geo-fence 1: The state of the device changed from rest to motion 1: The current logical state of the input is enabled state 1: Inside of the predefined range
report_type

The message type of ASCII format report

rx_ber

The network quality of the signal. The range is 0-7, and 99 is for unknown signal quality

0 0 The temperature alarm state: 0 The light sensor alarm state 0 The light sensor tamper state 0
1 - The current temp is lower that the low temp threshold specified by Min. Temperature. 0: Normal state 0: Normal State
2 -The current temperature is higher than the high temperature threshold specified by Max.Temp 1: Above threshold alarm state 1: Tamper alarm state
3: The current temperature is within the temperature threshold range. 2: Below threshold alarm state
4: The current temp is outside the temperature threshold range
rep_id

The type of the messages GTGEO, GTDOG and GTNMR.
For other reports, it is 0.

For GTGEO
0: Exit the corresponding Geo-fence

1: Enter the corresponding Geo-fence

For GTNMR
0: The sta
te of the device changed from motion to rest
1: The state of the device changed from rest to motion

For GTDOG
0:
Reboot periodically according to settings

For GTGEO
0:
The current logical state of the input port is disabled state
1:
The current logical state of the input is enabled state
