EMBEDDED APPLICATIONS FCT
This application note illustrates how an embedded
application can be created to provide a simple Telematics
demonstrator.
The radio device is connected to a GPS receiver via
UART3, a Telematics Core Service (TCS) is provided by
an embedded application script described here.
The script can be triggered to route data from the GPS
receiver via SMS on receipt of a command SMS. An
Administrative Front End application or GSM handset can
be used to issue the command, once the command has
been accepted the application in the radio device will reply
to the originator with an SMS containing positioning data
captured from the GPS receiver.
The Administrative Front End application may process the
data by plotting the position on a map for example.
The commands supported are:
• Request – send a single GPS update
• Schedule x – send GPS updates continually at 'x'
second intervals
• Stop – stop the current schedule process
The system is illustrated in figure 6.1
