Figure 1. GSM Tracker automatic execution settings

Before making any step-by-step testing make sure that all automatic execution settings are Off in Options -> Settings. Otherwise the program tries to automatically start different services at a few seconds interval, which is confusing, when trying to manually configure and test individual functions.

In other words, make sure that the settings are like shown in Figure 1, press the soft key Back and restart the Aspicore GSM Tracker application before making any other troubleshooting or testing.

Test each service (the three icons in the Aspicore GSM Tracker state view) individually one by one before trying to activate them simultaneously.

• Connect and disconnect GPS:

  Initially the status icon should be like

  Execute Options -> Connect GPS
  Check that the status icon changes to and you get meaningful position data to the screen. A good sign of an active Bluetooth connection to the GPS receiver is the UTC time field, whose value should go on in real time with a few seconds interval.
  
  Execute Options -> Disconnect GPS
  The status icon should change back to

• Connect and disconnect GPRS:
  Initially the status icon should be like

  Execute Options -> GPRS data -> Connect GPRS
  Check that the status icon changes to
  Execute Options -> GPRS data -> Send GPRS test msg
  Check that Aspicore's test web site received your test message. Detailed instructions in the following chapter.
  Execute Options -> GPRS data -> Disconnect GPRS

  The status icon should change back to

• Start and stop GSM cell tracking:
  Initially the status icon should be like

  Execute Options -> GSM -> Start Cell Tracking
  Check that the status icon changes to
  Execute Options -> GSM -> Stop Cell Tracking
   

  The status icon should change back to

• Exit the Aspicore GSM Tracker application
  This is the final step of the test that the services work individually. If the application exits smoothly, you can restart the application and start configuring the settings like you want. Now you can also turn on the automatic execution settings (Figure 1), if you want.

Make sure that the phone is not connected to the Internet via a PC. (The possibly installed PC Suite mRouter or similar PC connectivity link is disconnected).

Figure 3. Server IP and port query

You can use Aspicore's test server for testing. Aspicore's IP address and port number are shown in Figure 3.

Figure 4. Select access point dialog

Figure 5. GSM Tracker Log.

Also a small letter G inside a rectangle should appear instead of the antenna symbol in the top left corner of the screen. This shows that there is an active GPRS connection.

A note dialog with text Test msg sent should appear for a short period.

You need to submit your IMEI code and click Send button on the web page to see the data collected from your phone. 

The resulting web page shows the test messages received by Aspicore's test server from your phone. If there is a message with a suitable time stamp, your GPRS connection is working properly!

If your test message does not reach the test server and you know your GPRS connection is working, one possible reason is that your operator has got a NAT gateway, which filters out UDP datagrams to the IP address and port Aspicore's test server is using. You may want to try sending the test message over a dial-up connection (CSD, circuit switched data) or via another operator. If it works, the cause probably is a NAT gateway at your operator!
