Figure 4: Data flow of a Java application running on the module.

The diagram shows the data flow of a Java application running on the module. The data flow
of a Java application running in the debug environment can be found in Figure 15.
The compiled Java applications are stored as JAR files in Flash File System of module.
When the application is started, the JVM interprets the JAR file and calls the interfaces to
module environment.
The module environment consists of:
· Flash File System:
· TCP/IP:
· GPIO:
· DAI:
· ASC1:
· AT parser:
The Java environment on the module consists of:
· JVM:
· AT command API:
· File API:
· RS-232 API:
· IMP 1.0:
