Specifications

Java Midlet
Major benefits: integration into Java applications, no need for application
microcontroller, extremely cost-efficient hardware and software design –
ideal platform for industrial GSM applications.
The memory space available for Java programs is10.0 MB flash file
system and 1.8 MB RAM. Application code and data share the space in
the flash file system and in RAM.
