GL300 @Tracker Air Interface Protocol
<mode>: A hex numeric to determine how the function works. Each bit of the hex numeric
indicate different behavior that device could do. If the corresponding bit is 1, the device will
behave as the description. Otherwise, it won’t behave as the description.
Bit0(1): Suspend the report of FRI(including +RESP:GTGSM for FRI) and
Geo-Fence when it detects non-movement.
Bit1(2): Report the message +RESP:GTNMR to the backend server when it detects
non-movement.
Bit2(4): Report the message +RESP:GTNMR to the backend server when it detects
movement.
Bit3(8): Change the fix interval and send interval of FRI(including +RESP:GTGSM
for FRI) to <rest fix interval> and <rest send interval> when it detects non-movement. In the
case, it just modify the fix interval and send interval of FRI(including +RESP:GTGSM for
FRI) but not suspend the report of FRI(including +RESP:GTGSM for FRI) even if Bit0 is 1.
<Non-movement duration>: A time parameter to determine whether the device enters
non-movement status, i.e. if the motion sensor detects that the device keeps in non-movement
for a period of time defined by <Non-movement duration>, the device will be considered as
in non-movement status.
<Movement duration>: A time parameter to determine whether the device enters movement
status. If the motion sensor detects that the device keeps in movement for a period of time
defined by <Movement duration>, the device will be considered as in movement status.
<Movement threshold>: The threshold for the motion sensor to determine whether the device
is in movement. The less, the more likely to be treated as movement.
<rest fix interval>: the fix interval for the report of FRI when the device is in rest state if Bit3
of <mode> is 1.
<rest send interval>: the send interval for the report of FRI when the device is in rest state if
Bit3 of <mode> is 1.
<pm rest threshold>: The threshold for the EBK motion sensor to determine whether the
EBK enters non-movement status.
<pm motion threshold>: The threshold for the EBK motion sensor to determine whether the
EBK enters movement status.
<Urc report>: Enable or disable output sensor state through urc.
0: Do not output the sensor’s state to UART.
1: Output a URC to UART to indicate state changing. “SENSOR:REST” means state
changing from MOTION to REST. “SENSOR:MOTION” means state changing from
REST to MOTION.
