7 _ ATC comparison 1 Introduction This document describes the important points that should be taken into account in client s application design. As can be integrated with a wide range of applications, the application notes are described in great detail. This document can help you quickly understand interface specifications, electrical and mechanical details. With the help of this document and other application notes, user guide, you can use module to design and set-up mobile applications quickly. ATC_COMPARISON_V /9/2010

8 _ ATC comparison 2 There are some important performances of that are obviously different from module. These differences are described and listed as in the following table. Function URC after power on Combining AT commands Parameter setting and storage Auto-bauding SMS STK Description A HEX string such as FF FF FF FF will be sent out through serial port at the baud rate of immediately after is powered on. The string shall be ignored since it is used for synchronization with PC tool only. If fixed baud rate is set, RDY string will be sent out after power on and Call Ready string will be sent out after SIM card is initiated. +CPIN: READY or +CPIN: SIM PIN string will not be sent out by module. Semicolon shall be used as command delimiter only after an extended command, for example, ATE1&W&F+ICF?;+CFUN?;&W string can be executed successfully and ATE1;&W;&F string can not be executed. The AT commands listed in the table of AT&W chapter should be stored to user profile with AT&W for use after restart. Most other AT commands in V.25, 07.05, 07.07, GPRS will store parameters automatically and can be used after module restarts. Please refer to the following table for details. Only the strings AT or At (not at or at ) can be detected when auto-bauding is enabled. It is recommended that all AT commands shall be prefixed with AT. AT+IPR=0 setting to auto-bauding will take effect after module resets. However, if user wants to change DTE baud rate during module running, i.e from to 9600, DTR shall be used to urge auto-bauding progress. DTR shall be pulled up to invalid state at least 2 seconds by DTE and then pulled down to valid state. The step will urge auto-bauding progress and DCE will synchronize its baud rate after it receives string AT from the serial port. With GSM code, 160 characters maximum can be sent through a SMS. With UCS2 code, 70 characters maximum can be sent through one SMS. STK AT commands of are totally different from. And STK application note of module shall be referred for details. The following table describes the details of AT command parameters setting and storage. It is highly recommended that AT command parameters used by customer should be set after module is powered on.
