Copyright© Shanghai MobiletekCommunication Ltd 13 AT Command User Guide 3 AT COMMANDS The Mobiletek wireless module family can be controlled via the serial interface using the standard AT commands[1]. The Mobiletek wireless module family is compliant with: Hayes standard AT command set, in order to maintain the compatibility with existing SW programs. ETSI GSM 07.07 specific AT command and GPRS specific commands. ETSI GSM 07.05 specific AT commands for SMS (Short Message Service) and CBS (Cell Broadcast Service) Moreover Mobiletek wireless module family supports also Mobiletek proprietary AT commands for special purposes. N F LY ID NQ EN TI AL The following is a description of how to use the AT commands with the Mobiletek wireless module family. 3.1 Definitions The following syntactical definitions apply: Carriage return character, is the command line and result code terminator character, which value, in decimal ASCII between 0 and 255,is specified within parameter S3. The default value is 13. Linefeed character, is the character recognised as line feed character. Its value, in decimal ASCII between 0 and 255, is specified within parameter S4. The default value is 10. The line feed character is output after carriage return character if verbose result codes are used (V1 option used ) otherwise, if numeric format result codes are used (V0 option used) it will not appear in the result codes. <...> Name enclosed in angle brackets is a syntactical element. They do not appear in the command line. CO 1 The AT is an ATTENTION command and is used as a prefix to other parameters in a string. The AT command combined with other parameters can be set up in the communications package or typed in manually as a command line instruction. Copyright© Shanghai MobiletekCommunication Ltd 14 AT Command User Guide [...] Optional subparameter of a command or an optional part of TA information response is enclosed in square brackets. Brackets themselves do not appear in the command line. When subparameter is not given in AT commands which have a Read command, new value equals to its previous value. In AT commands which do not store the values of any of their subparameters, and so have not a Read command, which are called action type commands, action should be done on the basis of the recommended default setting of the subparameter. 3.2 AT Command Syntax The syntax rules followed by Mobiletek implementation of either Hayes AT commands or GSM/WCDMA/LTE commands are very similar to those of standard basic and extended AT commands. There are two types of extended command: N F LY ID NQ EN TI AL Parameter type commands. This type of commands may be "set" (to store a value or values for later use), "read" (to determine the current value or values stored), or "tested" (to determine ranges of values supported). Each of them has a test command (trailing =?) to give information about the type of its subparameters; they also have a Read command (trailing?) to check the current values of subparameters. Action type commands. This type of command may be "executed" or "tested". "executed" to invoke a particular function of the equipment, which generally involves more than the simple storage of a value for later use "tested" to determine: Whether or not the equipment implements the Action Command (in this case issuing the correspondent Test command - trailing =? - returns the OK result code), and if subparameters are associated with the action, the ranges of subparameters values that are supported. Action commands do not store the values of any of their possible subparameters. Moreover: The response to the Test Command (trailing =?) may be changed in the future by Mobiletek to allow the description of new values/functionalities. CO If all the subparameters of a parameter type command +CMD are optional, issuing AT+CMD= causes the OK result code to be returned and the previous values of the omitted subparameters to be retained. 3.2.1 String Type Parameters A string is either enclosed between quotes or not considered a valid string type parameter input. According to V25.ter space characters are ignored on the command line and may be used freely for formatting purposes, unless they are embedded in numeric or quoted string constants. Therefore a string containing a space character has to be enclosed between quotes to be considered a valid string type parameter (e.g. typing AT+COPS=1,0,"A1" is the same as typing AT+COPS=1,0,A1; typing AT+COPS=1,0,"A BB" is different from typing AT+COPS=1,0,A BB). A small set of commands requires always writing the input string parameters within quotes. This is explicitly reported in the specific descriptions. Copyright© Shanghai MobiletekCommunication Ltd 15 AT Command User Guide 3.2.2 Command Lines A command line made up of three elements: the prefix, the body and the termination character. The command line prefix consists of the characters "AT" or "at", or, to repeat the execution of the previous command line, the characters "A/" or "a/". The termination character may be selected by a user option (parameter S3), the default being . The basic structures of the command line are: ATCMD1 where AT is the command line prefix, CMD1 is the body of a basic command (nb: the name of the command never begins with the character "+") and is the command line terminator character ATCMD2=10 where 10 is a subparameter AT+CMD1 ;+CMD2=, ,10 These are two examples of extended commands (nb: the name of the command always begins with the character "+"[2]). They are delimited with semicolon. In the second command, the subparameter omitted. N F LY ID NQ EN TI AL +CMD1? This is a Read command for checking current subparameter values +CMD1=? This is a test command for checking possible subparameter values These commands might perform in a single command line as shown below: ATCMD1 CMD2=10+CMD1;+CMD2=, ,10;+CMD1?;+CMD1=? anyway it is always preferable to separate into different command lines the basic commands and the extended commands; furthermore it is suggested to avoid placing several action commands in the same command line, because if one of them fails, then an error message is received but it is not possible to argue which one of them has failed the execution. If command V1 is enabled (verbose responses codes) and all commands in a command line has been performed successfully, result code OK is sent from the TA to the TE, if subparameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code ERROR is sent and no subsequent commands in the command line are processed. If command V0 is enabled (numeric responses codes), and all commands in a command line has been performed successfully, result code 0 is sent from the TA to the TE, if sub-parameter values of a command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code 4 and no subsequent commands in the command line are processed. CO In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: or +CMS ERROR: . 2 The set of proprietary AT commands differentiates from the standard one because the name of each of them begins with either "^", "$" or "*". Proprietary AT commands follow the same syntax rules as extended command Copyright© Shanghai MobiletekCommunication Ltd 16 AT Command User Guide 3.2.3 Information Responses and Result Codes The TA response, in case of verbose response format enabled, for the previous examples command line could be as shown below: Information response to +CMD1?: +CMD1:2,1,10 Information response to +CMD1=? +CMD1(0-2),(0,1),(0-15) Final result code: OK Moreover, there are other two types of result codes: N F LY ID NQ EN TI AL Result codes that inform about progress of TA operation(e.g. connection establishment CONNECT) Result codes that indicate occurrence of an event not directly associated with issuance of a command from TE (e.g. ring indication RING). Here the basic result codes according to ITU-T V25Ter recommendation CO Result Codes Numeric form Verbose form 0 OK 1 CONNECT 2 RING 3 NO CARRIER 4 ERROR 6 NO DIALTONE 7 BUSY 8 NO ANSWER Copyright© Shanghai MobiletekCommunication Ltd 17 AT Command User Guide 3.2.4 Command Response Time-Out Every command issued to the Mobiletek modules returns a result response if response codes are enabled (default). The time needed to process the given command and return the response varies, depending on the command type. Commands that do not interact with the SIM or the network, and involve only internal set up settings or readings, have an immediate response, depending on SIM configuration(e.g., number of contacts stored in the phonebook, number of stored SMS), or on the network the command may interact with. In the table below are listed only the commands whose interaction with the SIM or the network could lead to long response timings. When not otherwise specified, timing is referred to set command.

This applies especially to applications that "sense" the OK text and therefore may send the next command before the complete code OK is sent by the module. It is in any case advisable to wait at least 20ms between the end of the reception of the response and the issue of the next AT command. If the response codes are disabled and therefore the module does not report any response to the command, then at least the 20ms pause time shall be respected. CO N F LY ID NQ EN TI AL During command mode, due to hardware limitations, under severe CPU load the serial port can lose some characters if placed in auto bounding at high speeds.

Mode can be either single or alternating (in the present document, terms "alternating mode" and "alternating call" refer to all GSM/UMTS bearer and teleservices that incorporate more than one basic service (voice, data, fax) within one call). When single mode is selected the call originating and hangup procedures are similar to procedures specified in ITU-T Recommendations V.250 [14], T.31 [11] and T.32 [12]. N F LY ID NQ EN TI AL NOTE: +CMOD shall be set to zero after a successfully completed alternating mode call. It shall be set to zero also after a failed answering. The power-up, factory (&F) and user resets (Z) shall also set the value to zero. This reduces the possibility that alternating mode calls are originated or answered accidentally.
