4.1.8 Tracing interface
The evaluation module has an interface for tracing the traffic in the M2M system
interface between the evaluation module and the Nokia GSM Connectivity
Terminal. Physically there are two D9 connectors on the PCB, one for tracing
the traffic from the evaluation module and one for tracing the traffic to the
evaluation module. Tracing requires compatible PC software that is supplied
with the Nokia M2M ADK.
4.2 SW FEATURES
The evaluation module SW is ported on the µC/OS-II operating system. An OS-
kernel is provided as a read-compiled library, so it can not be reconfigured
without recompiling. To re-configure the kernel, the developer needs the
µC/OS-II licence (Micrium). All other SW for the evaluation module is written in
portable ANSI-C and provided with the source codes. The following SW
components are included:
• Example applications
• ORB software module
• M2M system protocol software module
• OS and hardware wrappers
Example applications are described in Chapter 7 and the rest of the
components are described below.
A detailed description of the evaluation module SW can be found from the
Guide for Evaluation Module SW, which is included in the Nokia M2M ADK
documentation.
4.2.1 ORB SW module
An optimised ORB for an embedded environment is provided as a software
module. The size is about 60kbytes. Example implementation for integrating
this source code to a functional environment is provided.
Developers are free to use an ORB of they own, such as any commercial ones.
The integration procedure of ORB is described; as are connections to other
modules and available services.
4.2.2 System protocol SW module
The terminal to application module serial port datalink protocol is provided as a
software module. The size is about 60 kilobytes. Example implementation for
integrating this source code to a functional environment is provided.
