13/198 17 - lxe 108 566 uen 10 1 introduction to at commands this manual lists detailed information on the function of the at command set that can be used with the GR64 or gs64. this manual refers to the GR64 and gs64 as radio devices. if there is a difference in the functionality of the radio devices the GR64 and gs64, information will be listed separately. 1.1 related documentation this manual is supplied with an integ rator?s manual when you purchase a GR64 or gs64. if you choose to use the m2 m power support environment with the module you will also receive an application guide. 1.2 overview at commands, issued from a computer in your application are used to control and impl ement the functions of the module. using at commands, the following actions are possible: control of dce gprs call control supplementary service sim application tool kit control any embedded application in the device the manual contains a large number of s ony ericsson - specific commands in addition to those implemented in accordance with the 3gpp and itu - t recommendations. these commands are provided to enhance the functions of the module. the sony ericsson - specific commands are identified by the asterisk th at precedes the command (see the syntax description provided below). only commands that are listed in the at commands manual are supported unless otherwise stated. other commands may be listed by the module but these are only included for historical or leg acy reasons. 1.3 history of core module at commands manuals the following table describes the module software version documented in each at command manual version. at manual version gx64 software version pa4 qr5.1 (p1a050) pa4 qr5.2 (p1a051 - p1a055) pa4 q r6.0 (p1a056 - p1a060) pa6 qr7.0 (p1a061 - )
13/198 17 - lxe 108 566 uen 11 at manual version gx64 software version pa7 p1a062 - pa8 p1a068 - a p1a071 - p b 1 p1a072 - 1.4 syntax description this section provides a brief description of the syntax used for the GR64 and gs64 at command set. see the itu - t recommendation v.25te r for additional information. 1.4.1 conventions in this manual, the following conventions are used to explain the at commands. the name of the command that is to be entered. the parameter values that are defined for a certain command. the command line is terminated by the carriage return (or enter key) or ats3 command. line feed character or ats4 command. < > the term enclosed in angle brackets is a syntactical element. the brackets do not appear in the command line. [ ] square bra ckets are used to indicate that a certain item is optional. for example, sub - parameters of a command or an optional part of a response. the brackets do not appear in the command line. the default values of the supported parameters are indicated by using bold text when presenting the value. other characters, including ??', parenthesis, etc., appear in commands and responses as written. the final result codes ok, error, +cme error: and cms error: (see sections 1.3.3 at response syntax an d 1.4 error codes) are not listed under ?possible responses? for each at command. ok and error are listed if these are the only possible responses. 1.4.2 at command syntax the at standard is a line - oriented command language. each command is made up of the follow ing three elements: the prefix; the body; the termination character.
13/198 17 - lxe 108 566 uen 12 the prefix consists of the letters ?at?, which are derived from the first two letters of the word attention. the body is made up of the command, the parameter, and if applicable the assoc iated values . commands may be combined in the same command line. spaces between the individual bodies are ignored. basic syntax command the format of basic syntax commands is as follows: at[=][] ats0=0 (sets the automatic answer ing) additional commands may follow a command on the same command line without any character being required for separation. for the command d parameters, see the description for the command in question. a version of the basic syntax is: at extended syntax command at+= [] at*=[] at+cfun=0 (powers down the module) if several values are included in the command, they are separated by commas. it is also possible to enter commands with no values. add itional commands may follow an extended syntax command on the same command line if a semicolon ( ; ira 3b) is inserted after the preceding extended command as a separator. read command syntax the read command is used to check the current values of parameter s. type ???, after the command line: at+? at*? at? at+cscs? (show current character set) ?ira? (information text response) ok(final result code response)
13/198 17 - lxe 108 566 uen 13 test command syntax the test command is used to test wh ether the command has been implemented or to give information about the type of subparameters it contains. type ???, after the command line: at+=? at*=? at+cpas=? (shows supported values for the response parameters) cpas: (0, 3, 4 , 129, 130, 131) (supported values) ok (final result code) if the indicated is not recognized, the result code error is issued. possible responses are indicated both as :(list of supported) and (in most cases) th e actual range of the parameter values. 1.4.3 other terminology in this document, terms ?alternating mode? and ?alternating call? refer to all gsm bearer and teleservices that incorporate more than one basic service (voice, data, fax) within one call. 1.4.4 at respons e syntax the default mode response shown below is in text mode. for information about the atv dce response, see atv dce response format. possible formats for the result codes are: basic format result code, such as ok. the basic result code also has a numer ical equivalent. extended format result code, prefixed with a plus sign (+) or an asterisk (*): at+: at*: where the is the result code value, note that a single space character separates the colon char acter from the . if several values are included in the result code, they are separated by commas. it is also possible that a result code has no value. the extended syntax result codes have no numerical equivalent. they are always issued in alphabetical form. information text response may contain multiple lines separated by . the te detects the end of informational text responses by looking for a final result code response, such as ok. there are two types of result code responses as outlined below:
