ME3000 Module 1 General Description 1.1 AT Commands ME3006, ME3030 and ME3036 modules provide AT command interfaces, through which the modules could communicate with external devices. AT command set provided by ME3006, ME3030 and ME3036 modules not only covers standard GSM voice and short message applications, but adds some commands according to GSM specification and some ZTE exclusive commands for users. 1.1.1 Type of AT Commands Since AT command is used as a standard interface, the returned values and formats of the command are both fixed. As a whole, AT command could be divided into four types: z Non-parameter command: a type of simple command with the format of AT[+|&]<command>,e.g.: AT+CSQ, AT&W z Query command: used to inquire the current setting value. The format is AT[+|&]<command>?, e.g.: AT+CNMI? z Help command: used to list the possible parameters of the command. The format is AT[+|&]<command>=?, e.g.: AT+CMGL=? z Parameter command: normally used format which provides strong flexibility. The format is AT[+|&]<command>=<par1>,<par2>,<par3>… The returned values of this type of command are all the same. This will be clarified in details later. The basic frame format of the returned value is: <CR><LF><Response string><CR><LF> <CR><LF><OK/ERROR>[ERROR INFO]<CR><LF> 1.1.2 Returned Type and Format of AT Commands The following are ME3006, ME3030 and ME3036 modules’ AT command and their format and returned descriptions: z AT command format: --AT command starts with “AT” and ends with <CR>; --After the module runs, the serial port default setting will be: 8-digit data bit, 1-digit stop bit, no parity check, no CTS/RTS, data rate 115200bps. z AT command returned format: --<CR><LF><corresponding strings ><CR><LF> --An exceptional case: e.g.: AT+ZPOWEROFF (response format) directly return with “OK” z AT command status report (OK, ERROR): --If there is error in AT command format, “Error” will return; --If AT command executes successfully, “OK” will return. 8
