Protocol watchdog and Function key setting in Queclink GL300 GPS / GLONASS tracker

1. Protocol watchdog - the ability to automatically or

forcely restart the tracker The AT + GTDOG command is used to automatically restart the Queclink GL300 tracker either after a certain period of time or when the ignition is turned on in the vehicle.
Automatic, periodic reboot of the tracker helps to avoid the device functioning in an “exceptional state” for a long time. In addition to automatic reboot, the tracker supports forced reboot, on command of a digital input.



The command for activating the Protocol watchdog function in the GL300 tracker:
AT + GTDOG = gl300,1,60,30,1200,, 1,1,1,60,60,, FFFF $
In the Manager Tool - a program for configuring the tracker via a PC - this looks like that:



I note that it is not necessary to configure Queclink trackers through the Manager Tool; just send, for example, the above command via SMS to the mobile phone number on the SIM card that is installed in the tracker.

Consider the parameters that affect the operation of the Protocol watchdog.
Mode:
0: Do not activate the “protocol watchdog” function
1: Automatically reload the tracker in accordance with the values ​​defined in the “Interval” and “Time” cells
2: Reboot the tracker when the vehicle’s ignition is turned on, in case the tracker GL300 is connected to the ignition of the car
Ignition Frequency:
this parameter is used in the “2” mode from the Mode cell - rebooting the device when the ignition is turned on. The tracker automatically reboots when the vehicle ignition is turned on, if the time elapsed from the moment the last ignition was turned on to the current ignition is greater than the value specified in the Ignition Frequency cell; the value is indicated in minutes, the minimum interval is 10 minutes.
Time: time.
Interval: frequency of device reboot; This parameter depends on the options in the Unit cell. Unit: The unit of measure for the Interval cell is either days or hours.
Example: a) Interval = 1, Unit = 0: unit is day, Time = 1200, then the GL300 will reboot once a day at 1200; b) Interval = 1, Unit = 0: unit is hour, Time = does not matter, then the GL300 will restart once an hour from the moment the AT + GTDOG command was sent.

Report Before Reboot: before an automatic or forced restart, the tracker will send a + RESP: GTDOG report on its location to the server / mobile phone number (depending on the tracker's settings).

And, a very useful feature is the automatic restart of the tracker if there is no GSM signal or the GPRS channel is unavailable.

Gsm interval : the time during which there is no GSM signal, and in this regard, the tracker automatically reboots (minimum interval is 5 minutes).
Pdp interval:the time during which the GPRS channel is unavailable, and in this regard, the tracker automatically reboots (minimum interval is 5 minutes).

Input ID: port through which it is possible to implement a forced reboot of the tracker by sending a command either from the server or via SMS. “0” - disable forced activation of the reboot, “1” - port number, only the first port can participate in forced activation.

Type of report:
+ RESP: GTDOG, 1A0800,135790246811220 ,, 0 , 0,1,1,4.3, 92,70.0,121.354335,31.222073 ,
20090214013254,0460,0000,18d8,6141,00,2000.0,20090214093254,11F0 $
where 92,70.0,121.354335,31.222073 - azimuth, altitude, longitude, latitude, respectively.

0- depending on the value - 0, 1, 2 - the user will understand in connection with what event the device rebooted:
0 - automatic or forced
reboot 1 - reboot, because GPRS channel
2 is unavailable - reboot, because no GSM signal



2. Function key setting - configuring external buttons Tracker Queclink GL300
Tracker Queclink GL300 has a pair of external buttons, they can be set up on your own.




An example of a command for programming buttons:

AT + GTFKS = gl300,0,1,1,1,1,1,3,, FFFF $

In the Manager Tool - a program for configuring the tracker via a PC - it looks like this:



Consider the parameters that allow you to configure the buttons on one or another mode of operation.

Power key mode: programming the power button of the device (power button).
0: pressing the button does NOT turn off the device; sometimes it’s necessary - the inability to turn off the device forcibly, only automatic shutdown, after the battery’s discharge
1: pressing the button turns off the device
2: after pressing the power button and hold for 1.5 seconds, the SOS mode is activated

Full power up: the behavior of the tracker when external power is applied while the tracker is turned off.
0: when external power is supplied to the tracker, if the tracker is turned off, the tracker will not turn on automatically; external power is considered - a power adapter through the cigarette lighter of the car, a USB cable connected to a PC, etc.
1: when external power is supplied to the tracker, if the tracker is turned off, the tracker WILL turn on automatically; external power is considered - a power adapter through the cigarette lighter of the car, a USB cable connected to a PC, etc.

Function key mode: user button programming.
0: Ignore user button presses.
1: Geo-Fence mode - geo-zones mode. Turn on / off the geo-zone with the assignment of ID = 0 by long pressing the user button. In addition, + RESP: GTSWG will be sent to the server to enable / disable the geo-zone with ID = 0.
This function is convenient if we want to mark the boundaries of a territory, zone, site on the spot (in the field).
2: Geo-Fence Mode- geo-zones mode. Turn on / off the geo-zone with the assignment of ID = 0 by long pressing the user button. But the coordinates of the location where the button is pressed will be used as the center of the geo-zone with ID = 0 (compared to mode 1). Also, in addition, the tracker will send + RESP: GTGCR to the server with the result of GPS-fix and the inclusion status of the geo-zone with ID = 0.
3: SOS mode. After a long press for 3 seconds, the tracker will send a report with the last recorded coordinates, and then it will begin to determine the current location and, based on the GPS fix, will send an SOS message. It is also possible to send a report immediately with the current location. It depends on the settings in the SOS Report mode cell.

SOS Report mode:here the user has the opportunity to configure the sequence of reports in SOS mode when a user clicks a button.

1: Report only the last location immediately after pressing the user button in SOS mode
2: The tracker will try to fix and report the current location after pressing the user button in SOS mode
3: The tracker will report the last recorded coordinates (determined before the user button was pressed), and then try fix and report the current location and send the SOS message by the result of the fixation.

Report type:
+ RESP: GTSOS, 1A0800,135790246811220,, 0,0,1,1,4.3,92,70.0,121.354335,31.222073,
