AT Command Set

- For every channel a different <text> parameter can be stored.

- <text> will be output on the same logical channel the alarm was entered.

 

If not in multiplex mode, <text> will be output independent of the related

 

channel.

 

- The read command returns all pending alarms, independent on which

 

logical channel an alarm was entered. It´s up to the user to identify these

 

alarms by specific <text>s.

 

 

Examples

Example 1:

 

You may want to configure a reminder call for May 31, 2001, at 9.30h, including

 

the message "Good Morning".

 

Write command:

 

AT+CALA="01/05/31,09:30:00",0,0,"Good Morning"

 

OK

 

Do not switch off the GSM engine. When the alarm is executed the ME returns

 

the following URC:

 

+CALA: Good Morning

 

 

 

Example 2:

 

To set a fresh alarm using the same message as in Example 1, simply enter

 

date and time. <n>, <type>, <text>, <tlength> can be omitted:

 

AT+CALA="01/05/31,08:50:00"

 

OK

 

When the alarm is executed the URC comes with the same message:

 

+CALA: Good Morning

 

 

 

Example 3:

 

To configure the alarm mode, e.g. for May 20, 2001, at 8.30h, enter

 

AT+CALA="01/05/20,08:30:00"

 

OK

 

Next, power down the ME:

 

AT^SMSO

 

^SMSO: MS OFF

 

When the alarm is executed the ME wakes up to Alarm mode and displays a

 

URC. If available, this line is followed by the individual <text> most recently

 

saved. If no individual message was saved only the first line appears.

 

^SYSSTART ALARM MODE

 

+CALA: Good Morning

AT+CALA

Set alarm time

AT+CCLK

Set date and time of RTC

AT^SBC

In Alarm mode, you can only query the present current consumption and check

 

whether or not a charger is connected. The battery capacity is returned as 0, re-

 

gardless of the actual voltage (since the values measured directly on the cell are

 

not delivered to the module).

AT^SCTM

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.
