AT Command Set

Write command

AT+CIND=

[<stat>[,<stat> [,...]]]

Reference

GSM 07.07

The write command simply controls the registration / deregistration of indicators.

<stat>

0

Indicator is deregistered. The indicator cannot be presented as

 

 

+CIEV URC, but can be directly queried with AT+CIND?.

 

1

Indicator is registered, indicator event report is allowed.

Note

The indicator “call” changes its value as soon as a call has been established, that is when both interlocutors are connected.

The indicator “sounder” appears each time a tone is generated in the ME. For in- stance, a waiting call produces a tone, which will be thus indicated.

Examples

^SYSSTART

 

 

at+cpin=9999

 

 

OK

 

 

at+cind?

 

 

+CIND: 5,99,1,0,0,0,0,0

The battery is either full or an external supply

 

 

source is used. The bit error rate of the signal

 

 

quality is not available (since there no call in

 

 

progress), and the ME is registered to its home

 

 

network.

 

OK

 

 

at+cmer=2,0,0,2

Now, activate the Indicator Event Report with

 

at+cmer

 

 

OK

 

 

+CIEV: message,0

+CIEV: signal,99

 

 

+CIEV: service,1

 

 

+CIEV: sounder,0

 

 

+CIEV: call,0

 

 

+CIEV: roam,0

 

 

+CIEV: smsfull,0

 

 

atd"0123456";

You make a call.

 

OK

 

 

+CIEV: sounder,1

A set of +CIEV URCs reports is presented.

 

+CIEV: call,1

 

 

+CIEV: sounder,0

 

 

+CIEV: call,0

The receiver hangs up.

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.
