AT Java Open Framework (AJOF)

7.1

AT Commands

The TC65 AT Command Set [4] contains all of the standard AT commands needed to ope-
rate a GSM/GPRS mobile. Please note that no fax commands are supported when the TC65
is operated in the Java environment. Simply issuing individual AT commands can control the
TC65 module. See the "AT Command Set" to learn more about AT commands. The AT Java
Open Framework allows an application to be built without dealing with individual AT
commands. This framework sits on top of the AT command API.
The AT commands have been divided into six functional areas. Each area is represented as
a package. Documentation for the methods of each area and the AT commands covered by
these methods can be found in ...\Siemens\SMTK\TC65\AJOF\doc\index.html, [10].
Extensions are possible to this framework. The Java tutorial in Chapter 13 gives examples
on how to use this framework.
7.1.1

Mobile Engine Sstatus

This area abstracts AT commands which affect the ME status, either by setting or returning
device parameters. The methods supplied in this category are mostly query methods. Most
of the methods in this category can be called regardless of the ME's current status. The
values set by these methods remain valid after the method call is finished.
7.1.2

Voice Call Handling

This category provides the methods for the handling of voice calls. Some of these methods
can only be executed successfully when the module is in a particular state.
7.1.3

Short Message Service

There are two formats, text and PDU, for sending short messages. The developer can create
messages of both formats, however, AJOF handles SMs internally in the PDU format. With
this framework, sending a short message should be as simple as writing a string to the
screen. The methods provided do all the appropriate conversions for reading or preparing an
SM. These conversions are transparent to the application programmer.
7.1.4

Phonebook Features

The phonebook methods provide access to the phonebook storage media. This class
provides methods to select a storage medium, list the stored entries, write into, browse
through, read or delete from a storage medium.
7.1.5

Pin I/O

The pin I/O class provides methods for configuring the pins, writing to and reading from the
pins, configuring the pins as a port and listening to the pins/port.
