7. APPLICATION EXAMPLES
The Nokia M2M Application Development Kit includes application examples
that show how the Nokia M2M Platform application can be implemented. All
application examples are available in source codes that make application
development easier, as the codes can be copied, modified and used in the
customer’s own applications.
7.1 EVALUATION MODULE CONTROL APPLICATION
The evaluation module control application is an end-to-end application, i.e. the
evaluation module is controlled from the server end through the Nokia M2M
Gateway Trial Version, GSM network and Nokia GSM Connectivity Terminal.
The server application can query the current state of any individual input or any
combination of up to 8 inputs from the database at any time. In addition, the
server application can register its ORB to get an indication immediately, if any
state transition is detected in the input lines.
LEDs in the circuit board show the status of the digital outputs. When a digital
pin is set up, an LED is lit correspondingly. To verify analog outputs, an external
device is needed (e.g.,a potentiometer).
This application includes a very simple user interface in the server application
with radio buttons and scroll bars.
The evaluation module control application is implemented in Java (server
application) and C (embedded application).
7.2 TERMINAL END APPLICATIONS
These applications control the Nokia 30 and use CORBA messaging via an RS-
232 interface. To run the applications a terminal must be connected to the
evaluation module with the system connector (flat cable). The evaluation
module must be connected from the RS 232 port to a PC’s communication port
with a serial cable. The Nokia M2M Gateway Trial version is not needed with
these applications. The purpose of these applications is to show developers
how terminal IDLs can be used to control the terminal.
There are two applications: SetLed and SendSMS.
SetLed is used to control the terminal LEDs that are provided for application
usage.
SendSMS is used to send and receive SMS messages in the Nokia GSM
Connectivity Terminal connected to the PC by a serial cable.
