GL300 @Tracker Air Interface Protocol
<GPS on need>: Whether to close GPS chip after retrieving GPS position information.
0: Never close GPS chip
1: Close GPS chip after retrieving GPS information every time.
2: Never close GPS chip only in ignition on state or movement state.
3: Never open GPS chip.
<GPS fix delay>: This is the time to wait after GPS fixing succeed. After GPS fixing succeed,
the device will wait for a period of time (defined by <GPS fix delay>) and then get the result
of GPS fixing because maybe it is not accurate to get the position immediately after GPS
fixing succeed. (e.g. if <GPS fix delay> is set as 7, we will wait for 7 seconds after GPS
fixing succeed and then get the position as the result). The range of the parameter is 5 – 60,
and the default value is 5. Unit: second.
<Report items mask>: Bitwise report mask to configure the composition of all the uplink
message. Each bit represents a field in the uplink message. If some bit is set as 1, the
corresponding field will be filled if it is included in the uplink message. Otherwise, the field
will be empty.
Bit0(0001): <speed>
Bit1(0002): <azimuth>
Bit2(0004): <altitude>
Bit3(0008): GSM LAI and CI, including <mcc>, <mnc>, <lac>, <cellid>
Bit4(0010): <send time>
Bit5(0020): <Device name>
<Event mask>: A Hex value to configure which event reports can be sent to the backend
server: Each bit corresponds to a report message. And if the bit is set as 1, the corresponding
report message can be sent to the backend server. Otherwise, it can not be sent to the backend
server. Here is the mapping between each bit and each report message.
bit0(0001): +RESP:GTPNA
bit1(0002): +RESP:GTPFA
bit2(0004): +RESP:GTEPN
bti3(0008): +RESP:GTEPF
bit4(0010): Reserved
bit5(0020): +RESP:GTBPL
Bit6(0040): +RESP:GTBTC
Bit7(0080): +RESP:GTSTC
bit8(0100): +RESP:GTSTT
bit9(0200): Reserved
bit10(0400): +RESP:GTPDP
bit11(0800): +RESP:GTPNL
bit12(1000): +RESP:GTIGN and +RESP:GTIGF
bit13(2000): +RESP:GTIGL
<Gsm report>:
If GPS fixing for the report m
essage +RESP:GTSOS, +RESP:GTRTL,
+RESP:GTLBC and +RESP:GTFRI were failed and the parameter <Gsm report> was set as
1, the terminal reports the message +RESP:GTGSM, including the information of the service
cell and the neighbour cells after those messages.
0: Not allow the cells’ information report after failed to get GPS position.
