2. INTRODUCTION
As we are quickly moving towards the world of third generation mobile traffic,
more attention than ever is being paid to the wireless data market. So far, we
have seen only the first steps towards the mobile information society, but it has
already become clear that wireless data means more than just web browsing.
M2M communication is just one of the aspects of wireless data services. The
market potential is huge; new applications are emerging continuously and
operators are searching for opportunities for growth. The telecom industry is
shifting in the direction of end-to-end solutions, which requires reliable
communication and information transfer.
The Nokia M2M Platform is a complete, wireless, end-to-end solution for M2M
communication. Nokia M2M ADK offers development tools for application
development on the Nokia M2M Platform.
2.1 NOKIA M2M PLATFORM
The Nokia M2M Platform is an object-oriented software platform based on the
widely accepted industry standard. The Nokia M2M Platform is adaptable to a
wide range of purposes and communication methods, and it meets the needs of
many different applications. The Nokia M2M Platform hides mobile network
complexities and, thanks to CORBA method calls, is transparent to different
machines, operating systems, and language implementations.
The Nokia M2M Platform consists of the Nokia M2M Gateway and Nokia GSM
Connectivity Terminals as shown in Figure 1.
1 CORBA is a widely distributed computing infrastructure, standardised by the Object Management
Group (OMG) consortium. In short, CORBA applications are composed of objects that can locate in
different machines. These objects have services, and they are utilised with request messages.
CORBA hides the underlying transfer network, such as the Internet or GSM network, an also the
underlying protocols so that a user can use the functions as local procedure calls.

2.2 OTHER NOKIA M2M PLATFORM PRODUCTS
2.2.1 Nokia M2M Gateway
The Nokia M2M Gateway provides wireless CORBA access and interoperability
to the Internet. The Nokia M2M Gateway bridges the GSM network and Internet
by wireless connection establishment and protocol translation between
applications located on the Internet and in remote devices. The CORBA
middleware is optimised for the wireless bearer, and the Nokia M2M Gateway
translates the protocol into a standard CORBA Internet Inter-ORB Protocol
(IIOP).
The following three editions of the Nokia M2M Gateway are available:
Nokia M2M Gateway Corporate Edition is targeted for companies choosing to
own and manage the gateway along with the server application. This gives the
company independence and control over the service quality. Access to SMS-C,
USSD-C and GGSN can be rented from the network operator.
Nokia M2M Gateway Service Provider Edition is targeted for telecom
operators and other Nokia M2M Gateway service providers (GSP). The
distributed architecture enables the hosting and maintaining of applications for
many customer companies. Separate Gateway Access Software is provided for
client companies and the service-provider. Access control from terminals to the
company intranet is handled by the Gateway Access Software so that the
companies can freely manage the access rights.
Nokia M2M Gateway Trial Version is intended for trial purposes and for
testing the applications in the development phase. The Nokia M2M Trial

Supply. The input voltage range is 6.4 V - 13.5 V, and the absolute maximum
rating is 16.5 V.
This power interface is not needed if power is supplied from the terminal
through the M2M system connector. Alternatively, the evaluation module can
supply the terminal through this same interface.
4.1.3 Service interface
The service interface in the evaluation module is a D9 female connector with an
output voltage range of 0 – 3.3 V. This interface supports tracing the SW
running in the evaluation module and downloading a remote-end application
SW into the evaluation module. Controlling the evaluation module with a PC is
also possible through this interface.
4.1.4 RS-232
The evaluation module has a D9 connector for the standard RS-232 interface.
Through this interface, the developer can control the Nokia GSM Connectivity
Terminal connected to the M2M system interface with AT commands. Through
this interface the evaluation module can be used as a CORBA over an RS-232
adapter when testing the Nokia 30 terminal.
4.1.5 Digital output interface
One D9 connector in the evaluation module is reserved for digital outputs.
There are 8 conventional digital outputs with HIGH and LOW states in a voltage
range of 0 V – 3.3 V. LEDs on the evaluation module circuit board indicate the
ON/OFF status of the digital outputs.
4.1.6 Digital input interface
One D9 connector in the evaluation module is reserved for digital inputs. There
are 8 conventional digital inputs with HIGH and LOW states in a voltage range
of 0V - 5V. These inputs also have a tolerance of 5 volts, for example for
interfacing with 5V logic.
4.1.7 A/D and D/A converter interface

The Nokia M2M Gateway Trial Version is intended for trialling the Nokia M2M
Platform technology and for testing purposes in the software development
phase. The server application may be run on the same host as the Nokia M2M
Gateway Trial Version.
Due to the limited connectivity services offered, the Trial Version has restricted
suitability for commercial applications.
5.1 FEATURES
5.1.1 Bearers
The Nokia M2M Gateway Trial Version supports GSM short message service
(SMS) and data calls (CSD) through a GSM terminal attached to the gateway
host machine.
5.1.2 Traffic Optimisation
The Nokia M2M Gateway Trial Version optimises traffic on the wireless path by
carrying out the CORBA naming service lookup for the actual object reference
called. The address is the developer’s chosen text string with which the object
has been registered to the naming service.
This feature optimises the air interface usage for SMS connections and speeds
up the operation of the Nokia M2M Application Development Kit (Nokia M2M
Platform)
5.1.3 Messaging Reliability
The Nokia M2M Gateway Trial Version uses the reliable Transmission Control
Protocol (TCP) for Internet connectivity. Wireless communications utilise
message acknowledgement and retransmission for all bearers to ensure
message delivery. In cases where the message cannot be delivered to the
recipient, the originator is informed of the communications failure.
5.2 SYSTEM REQUIREMENTS
The Nokia M2M Gateway Trial Version is a software product running on

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.

These terminal end applications are implemented with C.
7.3 SERVER END EXAMPLE1 AND EXAMPLE2 APPLICATIONS
Nokia M2M ADK includes example applications for controlling the terminal
connected to the evaluation module at the embedded end from the server side.
In example application 1, the server end queries the remote terminal for a list of
names of objects that are registered to the Object Request Broker (ORB) of the
terminal (i.e. objects that can be found from the remote terminal). Example
application 2 causes an LED to blink in the remote terminal. Both applications
show how terminal IDLs can be used remotely.
These application examples are implemented with Java.
7.4 REMOTE I/O CONTROL APPLICATION
This application example shows how the remote I/O control feature of the Nokia
30 GSM Connectivity terminal can be used. The Nokia 30/31 offers remote
input/output control for the M2M System Connector. Three pins of the M2M
System Connector can be configured as digital or analog input, and five pins as
digital output. Digital input states or analog voltages are sent over the network
to the server where they are interpreted.
This example application includes a graphical user interface with scroll bars and
radio buttons for easy controlling and monitoring. The states of the I/O pins
(analog/digital) can be changed.
This application is implemented with Java.

8. M2M TRACER
The Nokia M2M Application Development Kit includes a tracer for logging the
traffic over the M2M system interface between the evaluation module and the
Nokia GSM Connectivity Terminal.
The tracer includes a tracer interface in the evaluation module and PC
software. The PC is connected to the evaluation module tracing interface by a
he/she wants. Logs are saved in text files.
Traces can also be taken directly from the evaluation module by connecting the
PC to the evaluation module’s service interface with a serial cable, see
evaluation module service interface Chapter 4.1.3.

9. IDL COMPILER
The Nokia M2M ADK includes an IDL compiler for the embedded application
development. The IDL compiler is a program that reads IDL files and produces
the necessary programming language-specific files: skeletons and stubs. These
translate message data into a form that is appropriate for cross-platform
code-calling a method on the server only sees a local method call, which is no
different from the mundane method-calls in non-distributed programming. The
ORB, together with the generated stub and skeleton code, hides the distribution
completely.
