GL300 @Tracker Air Interface Protocol
<Mode>: The working mode of the fixed report.
0: Disable fixed report function.
1: Enable the scheduled timing report.
2: Enable the scheduled distance report. Report each time the straight length that the
device moved has exceeded the specified distance. It ignores the detail path the
device has passed along. This function is invalid unless the GPS chip opens always.
Unit: Meter.
3: Enable the scheduled mileage report. Report each time the path length that the
device moved has exceeded the specified length. It calculates the length of the detail
path the device has passed along. This function is invalid unless the GPS chip opens
always. Unit: Meter.
4: Optimum Report. Simultaneously observe time interval and path length between
two adjacent reports. Report device position if the calculated time interval per
current time against the last report time is greater than the <Send Interval>, and the
length of path between the current position and the last position is greater than the
<Mileage> setting. There is a precondition for the function. It is that <GPS on need>
must be 0 (Never close GPS chip) or 2 (Never close GPS chip in ignition on state or
movement state).
5: Enable the scheduled timing report for GSM.
6: Fixed Time or Mileage Report. Simultaneously observe both time interval and path
length between two adjacent reports. Report device position if the calculated time
interval per current time against the last report time is greater than the <Send
Interval>, or the length of path between the current position and the last position is
greater than the <Mileage> setting.
<Discard no fix>: 0 to report last known GPS position if there is no GPS fix, 1 to send
nothing if there is no GPS fix.
<Begin time>: The start time of scheduled fixed report. The valid format is “HHMM”. The
value range of “HH” is “00”-“23”. The value range of “MM” is “00”-“59”. It is noticed to
use system time here.
<End time>: The end time of scheduled fixed report. The valid format and range are same as
<Begin time>.
<Check interval>: The interval time to fix GPS when the device attached vehicle is ignition
off, its value range is 5-86400 and the unit is second.
<Send interval>: The period to send the position information when the device attached
vehicle is ignition off. The value range is 5-86400 and the unit is second.
<Ignition check interval>: The interval time to fix GPS when the device attached vehicle is
ignition on, its value range is 5-86400 and the unit is second.
<Ignition send interval>: The period to send the position information when the device
attached vehicle is ignition on. The value range is 5-86400 and the unit is second.
<Report mask>: Bitwise report mask to configure the composition of GPS position
information for fixed report. If some bit is set as 1, the corresponding field will be filled in
the position related message. Otherwise, the field will be empty.
Bit0(0001): <speed>
Bit1(0002): <azimu
