AT Command Set

7.1AT^SSTA Remote-SAT Interface Activation

Test command

Response

AT^SSTA=?

Read command

AT^SSTA?

^SSTA:(list of supported <state>s), (list of supported <alphabet>s) Parameter description see below.

The read command can be used to request the current operating status and the used alphabet of the Remote-SAT interface.

Response

^SSTA:<state>,<alphabet>,<allowedInstance>,<SatProfile> <state> device state:

<allowedInstance>

0SAT is already used on an other instance (logical channel in case of the multiplex protocol). Only test and read com- mands can be used.

1SAT may be started on this instance via the write version of this command (see below).

<SatProfile>

SAT profile according to GSM 11.14.

The profile tells the SIM application which features are supported by the SIM Application Toolkit implemented by the ME.

Write command

AT^SSTA=

<mode>

[,<Alphabet>]

Reference

Siemens

The write command is used to activate the AT command interface to the SIM Application Toolkit in the ME, and must be issued after every power on. How- ever, removing and inserting the SIM does not affect the activation status.

SAT commands which are not using the AT interface (non MMI related SAT commands , e.g. PROVIDE LOCAL INFORMATION) may be executed without activating Remote-SAT.

Response

OK

Parameter

<mode>

1Activate Remote-SAT (to enter state IDLE)

<Alphabet>

0ANSI character set

Input of a character requests one byte , e.g. “Y”.

1UCS2

To display the 16 bit value of characters represented in UCS2 alphabet a 4 byte string is required, e.g. “0059” is coding the character “Y”. For details please refer to ISO/IEC 10646.

MC35 specifications

The Siemens MC35 is a compact and versatile modem designed primarily for mobile communication, data transmission, and machine-to-machine (M2M) applications. Launched in the early 2000s, it quickly became popular due to its blend of performance, reliability, and ease of integration, making it a solid choice for developers and businesses.

One of the key features of the MC35 is its support for GSM and GPRS technologies. This allows it to connect seamlessly to various networks, enabling users to transmit data at speeds that were impressive for its time. The GPRS capability can offer data rates of up to 171.2 kbps, allowing for efficient data transfer even in areas with limited connectivity.

The MC35 is designed to support both SMS and voice functionalities, making it adaptable for a range of applications. This includes remote monitoring, telemetry, and alarm signaling. The ability to send and receive SMS messages is a significant advantage for applications that require immediate alerts and notifications, enhancing its utility in security systems and industrial automation.

Furthermore, the modem is equipped with a range of interfaces, including serial communication (RS232), which makes it compatible with various hardware devices. This facilitates easy integration into existing systems, whether for industrial machinery or consumer electronics. Additionally, it features a robust software development kit (SDK), which enables developers to create custom applications tailored to their specific requirements.

Power consumption is another notable characteristic of the Siemens MC35. It is engineered to be energy-efficient, which is especially important for battery-operated devices or systems that require a prolonged operation without frequent recharging or maintenance.

In terms of physical characteristics, the MC35 is compact and lightweight, allowing it to fit into various enclosure designs without occupying much space. Its durability ensures it can perform reliably in different environments, making it suitable for outdoor and industrial applications.

To summarize, the Siemens MC35 stands out as a reliable modem with a rich feature set that includes GSM and GPRS support, SMS and voice capabilities, easy integration through various interface options, and energy-efficient operation. Its adaptability makes it a valuable tool for a wide array of communication and data transmission tasks, solidifying its place in the evolution of mobile communications technology.
