AT Command Set

4.32 AT+CPBR Read current phonebook entries

Test command

AT+CPBR=?

Execute command

AT+CPBR=<ind

ex1>[,<index2>]

Example

Reference

GSM 07.07

Response

TA returns location range supported by the current storage as a compound value and the maximum length of <number> and <text> fields.

Note:

If SIM storage is selected, the length may not be available. If storage does not offer format information, the format list should be empty parentheses.

+CPBR: (list of supported <index>s), <nlength>, <tlength> OK

If error is related to ME functionality:

+CME ERROR: <err>

Parameter

 

<index>

supported range of location numbers (maximum number de-

 

pends on storage type)

<nlength>

max. length of phone number, normally 20, for a small num-

 

ber of locations 40

<tlength>

max. length of text assigned to phone number (depending on

 

storage type 16 - 18 characters including blanks)

Response

TA returns phonebook entries in location number range <index1> ... <index2> from the current phonebook memory storage selected with +CPBS. If <index2> is left out, only location <index1> is returned.

+CPBR: <index1>, <number>, <type>, <text>[<CR><LF>+CPBR: .....+CPBR: <in-

dex2>, <number>, <type>, <text>] OK

If error is related to ME functionality:

+CME ERROR

Parameter

 

<index1>

location number where reading starts

<index2>

location number where reading ends

<number>

phone number

<type>

type of address octet in integer format; 145 when dialling string

 

includes international access code character “+”, otherwise 129.

<text>

string type field of maximum length <tlength>. Character set as

 

specified with +CSCS.

1.First, run the Test command to find out the maximum range of entries stored in the active phonebook:

AT+CPBR=?

TA returns the supported values in the format: +CPBR: (1-100),20,17 where 100 is the supported range of location numbers, 20 is the length of the phone number and 17 is the maximum length of the text associated text.

2.Now, run the Execute command to display the phonebook entries sorted by location numbers.

AT+CPBR =1,100

+CPBR 1,"+999999",145,"Charlie" +CPBR: 2,"+777777",145,"Bill" +CPBR: 3,"+888888",145,"Arthur" .........

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.
