SIM7100_Internet_Service_Application_Note_V0.01.doc 6 2015-02-10 AT Command Set For Internet Service 2 2.1 AT Interface Synopsis Interface settings Between Customer Application and the Module, standardized RS–232 interface is used for the communication, and default values for the interface settings as following: 115200bps, 8 bit data, no parity, 1 bit stop, no data stream control. 2.2 AT command syntax The prefix “AT” or “at” (no case sensitive) must be included at the beginning of each command line (except A/ and +++), and the character <CR> is used to finish a command line so as to issue the command line to the Module. It is recommended that a command line only includes a command. When Customer Application issues a series of AT commands on separate command lines, leave a pause between the preceding and the following command until information responses or result codes are retrieved by Customer Application, for example, “OK” is appeared. This advice avoids too many AT commands are issued at a time without waiting for a response for each command. In the present document, AT commands are divided into three categories: Basic Command, S Parameter Command, and Extended Command. 1. Basic Command The format of Basic Command is “AT<x><n>” or “AT&<x><n>”, “<x>” is the command name, and “<n>” is/are the parameter(s) for the basic command, and optional. An example of Basic Command is “ATE<n>”, which informs the TA/DCE whether received characters should be echoed back to the TE/DTE according to the value of “<n>”; “<n>” is optional and a default value will be used if omitted. 2. S Parameter Command The format of S Parameter Command is “ATS<n>=<m>”, “<n>” is the index of the S–register to set, and “<m>” is the value to assign to it. “<m>” is optional; in this case, the format is “ATS<n>”, and then a default value is assigned. 3. Extended Command The Extended Command has several formats, as following table list: Table 2-1: Types of Extended Command Command Type Syntax Comments Test Command AT+<NAME>=? Test the existence of the command; give some information about the command subparameters. SIM7100_Internet_Service_Application_Note_V0.01.doc 7 2015-02-10 AT Command Set For Internet Service Read Command AT+<NAME>? Check the current values of subparameters. Write Command AT+<NAME>=<…> Set user-definable subparameter values. Execution Command AT+<NAME> Read non-variable subparameters determined by internal processes. NOTE The character “+” between the prefix “AT” and command name may be replaced by other character. For example, using “#” or “$”instead of “+”. 2.3 Information responses If the commands included in the command line are supported by the Module and the subparameters are correct if presented, some information responses will be retrieved by from the Module. Otherwise, the Module will report “ERROR” or “+CME ERROR” or “+CMS ERROR” to Customer Application. Information responses start and end with <CR><LF>, i.e. the format of information responses is “<CR><LF><response><CR><LF>”. Inside information responses, there may be one or more <CR><LF>. Throughout this document, only the responses are presented, and <CR><LF> are intentionally omitted. SIM7100_Internet_Service_Application_Note_V0.01.doc 8 2015-02-10 AT Command Set For Internet Service 3 Simple Mail Transfer Protocol Service Simple Mail Transfer Protocol (SMTP) is an internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks, and it is a text-based protocol. To sending an e-mail successfully, TE must set some mandatory parameters for the SMTP client correctly, such as SMTP server address, sender and recipient address. After the process of sending an e-mail is started, SMTP Client will initiates a Transmission Control Protocol (TCP) session with the SMTP server to send e-mail header and body. In addition, attachments selected from file system can be sent along with an e-mail message, total size up to 10MB or maximal number up to 10. Unsolicited Result Code (URC) “+SMTP: SUCCESS” is present from SMTP client to indicate that sending an e-mail is successful, and the TCP session for SMTP service is closed. If sending an e-mail is unsuccessful, other URCs will be returned to TE. Sender/recipient address and e-mail subject are used to construct the e-mail’s header. In addition, data and time are also present in the e-mail’s header, which are gotten from the module. So it is recommended to set Real Time Clock (RTC) and time-zone for the module. 3.1 AT+SMTPSRV SMTP server address and port number Description The synchronous command is used to set SMTP server address and server’s port number. SMTP client will initiate TCP session with the specified server to send an e-mail. If the process of sending an e-mail is ongoing, the command will return “ERROR” directly. Read command returns current SMTP server address and port number. Execution command will clear SMTP server address and set the port number as default value. NOTE After an e-mail is sent successfully or unsuccessfully, SMTP server address and port number won’t be cleared. SIM PIN YES References Vendor Syntax Test Command AT+SMTPSRV=? Read Command AT+SMTPSRV? Write Command AT+SMTPSRV=<server> [, <port>] Execution Command Responses +SMTPSRV: (list of supported <port>s) OK Responses +SMTPSRV: <server>, <port> OK Responses OK Responses SIM7100_Internet_Service_Application_Note_V0.01.doc 9 2015-02-10 AT Command Set For Internet Service AT+SMTPSRV OK Defined values <server> SMTP server address, non empty string with double quotes, mandatory and ASCII text string up to 128 characters. <port> Port number of SMTP server in decimal format, from 1 to 65535, and default port is 25 for SMTP.

If SMTP server requires authentication while logging in the server, TE must set the authentication control flag and provide user name and password correctly before sending an e-mail. If the process of sending an e-mail is ongoing, the command will return “ERROR” directly. Read command returns current SMTP server authentication control flag, if the flag is 0, both <user> and <pwd> are empty strings. Execution Command cancels SMTP server authentication and clear user name and password. NOTE After an e-mail is sent successfully or unsuccessfully, server authentication won’t be cleared. SIM PIN YES References Vendor Syntax Test Command AT+SMTPAUTH=?

Through AT commands, the POP3 client provides the basic functionality. Things that can be done via POP3 client include: Retrieve e-mail from POP3 server and delete it on the server. Retrieve e-mail from POP3 server but not delete it on the server. Ask whether new e-mail has arrived but not retrieve it. Peek at e-mail whether it is worth retrieving. 4.1 AT+POP3SRV POP3 server and account Description The synchronous command is used to set all parameters to get and e-mail from POP3 server, including server address, port number, user name and password. If POP3 client isn’t free, the command will return “ERROR” directly. Read command returns current all information about POP3 server and account. Execution command will clear POP3 server address, user name and password, and set server’s port number as default value.
