Java platform
JDK Version: 1.4.2_09
Java Virtual Machine with APIs for AT Parser, Serial Interface, FlashFileSystem
and TCP/IP Stack.
Major benefits: seamless integration into Java applications, ease of program-
ming, 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 is around 1.7 MB in the flash file
system and around 400k RAM. Application code and data share the space in the
flash file system and in RAM.
SIM Application Toolkit SAT Release 99
TCP/IP stack Access by AT commands
IP addresses IP version 6
Remote SIM Access AC65/AC75 supports Remote SIM Access. RSA enables AC65/AC75 to use a
remote SIM card via its serial interface and an external application, in addition to
the SIM card locally attached to the dedicated lines of the application interface.
The connection between the external application and the remote SIM card can be
a Bluetooth wireless link or a serial link.
The necessary protocols and procedures are implemented according to the “SIM
Access Profile Interoperability Specification of the Bluetooth Special Interest
Group”.
Firmware update Generic update from host application over ASC0, ASC1 or USB. Over-the-air
(OTA) firmware update is possible via SPI interface.
