State view, satellites out of sight
The main screen contains two tabs: State and Log. You can navigate between the tabs with left and right arrow keys.
The State view contains three icons showing the connection state and a few dynamic text fields showing most important GPS data values.
The leftmost icon
shows whether the Bluetooth connection to the GPS
receiver is active or not. Explanation:
- Figure 1: GPS not connected.
- Figure 2: GPS connected, three satellites in sight
- Figure 3: GPS connected, but the satellites are out of sight and thus the position fix is not valid (Note the letter V before the latitude degrees).
The middle icon 
shows the GPRS connection status. Explanation:
- Figure 1: GSM tracker is not connected to the database server.
- Figure 2 and 3: GSM tracker is connected to the database server. (Actually GSM tracker has requested the system to open an UDP socket to the logging database server IP and port. Because the server does not confirm the connection, this icon does not guarantee that the connection works.)
The rightmost icon
shows whether the GSM network cell
tracking has been activated or not. Explanation:
- Figure 1: Cell tracking is not active
- Figure 2 and 3: Cell tracking has been activated
The active cell tracking means, that the program has asked the Symbian OS to inform it about changes in the current network cell. Whenever the cell changes and the cell tracking is active, the program does the following:
- If the setting "Cell change beep" is on, the program beeps, shows a short note dialog and adds cell information to the log.
- If the setting "Cell trigger" is on and GPRS connection has been opened, the program transmits network cell data together with possible GPS location data to the database server.
The UTC time field shows the time from the latest interpreted data read from the Bluetooth GPS. UTC time should go on in real time with a few seconds interval. This is a good indication that the Bluetooth GPS connection is working and is in sync. The number of currently visible satellites is shown at the end of the UTC time row.
The data row with label Msg at the bottom of the state view shows counters for the NMEA messages received from the Bluetooth GPS. The first counter is the total count of all the received NMEA messages since the application start. The second counter shows the number of NMEA messages received since the previous display refresh. The display is periodically redrawn with a few seconds interval.

This chapter explains the meaning of each configuration settings item.
1 Store GPS BT name
- On: Do not show the Bluetooth device selection dialog, when issuing the connect GPS command. Connect to the same Bluetooth device as on the previous time without asking the user to choose the device.
- Off: Ask the user to choose the Bluetooth device, when the connect GPS command is executed.
2 On startup GPS
- On: Causes automatic execution of connect GPS command when the application is started and whenever the GPS connection is lost.
- Off: User must manually choose the connect GPS command from the Options menu to get connected with the Bluetooth GPS.
3 On startup GPRS
- On: Causes automatic execution of connect GPRS command when the application is started and whenever the GPRS connection is lost. Use the stored GPRS Server IP and GPRS Server Port numbers instead of asking them interactively. Opens an UDP socket to the logging database server. The socket must be open before any information can be sent to the server.
- Off: User must manually execute the connect GPRS command from the Options / GPRS data menu to open an UDP socket to the logging database server IP and port. The UDP socket must be open before any data

4 On startup tracking
- On: Causes automatic execution of Start Cell Tracking command when the application is started.
- Off: User must manually execute the Start Cell Tracking command from the Options / GSM menu to enable some action based on GSM network cell change. Possible actions are: 1) show a note dialog with a beep tone each time the network cell changes, 2) send cell data possibly together with GPS coordinates to the database logging server each time the network cell changes.
NB. Series 60 version 2.x phone owners Please read known issues before switching this setting on.

5 Cell change beep
- On: Show a note dialog with a beep tone each time the network cell changes. Add cell change information to the list in the log view. Cell tracking must be activated or otherwise this settings item has no effect.
- Off: Be silent about the cell changes. However, send data action may still be fired based on cell change even if this settings item is Off.
6 Time trigger
- On: Send GPS coordinate data periodically to the logging database server every <Time period, min> minutes. Requirements: GPS and GPRS must be connected, before this settings item has any effect.
- Off: Do not use a timer based send data action.
7 Time period, min
The time interval in minutes for timer based GPS data send action. Must be greater than zero for the trigger to work. In addition, Time trigger must be switched On.

8 Cell trigger
- On: Send GPS coordinate data together with the GSM cell information to the logging database server each time the network cell changes. Requirements: GPRS must be connected and cell tracking must be activated, before this settings item has any effect. If this trigger is switched on and the GPRS is connected before the cell tracking is activated, the current network cell at the activation time gets immediately transmitted to the server.
- Off: Do not use a GSM network cell based send data action.
9 Distance trigger
- On: Send GPS coordinate data to the logging database server, when the current position fix differs at least by <Distance, meters> from the previously sent position fix. Requirements: GPS and GPRS must be connected, before this settings item has any effect.
- Off: Do not use a distance based send data action.
10 Distance, meters
The threshold distance, which causes GPS data send action, when the distance trigger is set on. In addition, Distance trigger must be switched On.

11 GPRS Server IP
The IP address of the logging database server. The GSM Tracker application sends the GPS data and / or GSM cell data to this IP address as UDP datagram. You must have a GPRS service subscription from your GSM service provider and a suitable Internet Access point created in you phone's Connection settings.
If you are using a public internet GPRS access point, you can use Aspicore's test server for testing purposes. Aspicore's IP address is shown in Figure 9. You can see the data stored by Aspicore's test server at URL http://www.toimii.com/gps/. You need to submit your IMEI code to see the data collected from your phone.
12 GPRS Server Port
The UDP port, the logging database server is listening. Aspicore's test server is currently listening on port 1002.

13 Diagnostics mode

14 Store Access Point
- On: Do not show the Select access point dialog, when issuing the connect GPRS command. Connect to the same Internet access point (IAP) as on the previous time without asking the user to choose the IAP.
- Off: Ask always the user to select access point, when the connect GPRS command is executed.

15 On startup backlite
- On: Causes automatic execution of keep backlight on command when the application is started.
- Off: Backlight is in power save mode when the application is started. The backlight is de-activated after approximately 13 seconds of inactivity. You can still manually execute the keep backlight on command from the Options menu, but the command does not stay in force when you restart the application.
16 Global backlight
- On: This setting makes the keep backlight on command to affect also other applications even when the Aspicore GSM Tracker is not in foreground. This setting does not turn the backlight on. It adjusts the scope of the keep backlight on command.
- Off: This setting makes the keep backlight on command to work only locally, when Aspicore GSM Tracker is running in foreground. Backlight power save mode is always enabled, when the application is put to the background even if the keep backlight on command is active.
(End key, i.e. Red phone key)
to leave Aspicore GSM Tracker running in the background while using your phone
to other purposes.
(Menu key). The application switching window opens
showing a list of applications that are currently open. Scroll to an
