8 1 General 1.1 of AT Commands AD3812, MG3630 modules provide AT command interfaces, through which the modules could communicate with the external devices 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: Non-parameter command: a type of simple command with the format of AT[+ &]<command>,e.g.: AT+CSQ, AT&W Query command: used to inquire the current setting value. The format is AT[+ &]<command>?, e.g.: AT+CNMI? Help command: used to list the possible parameters of the command. The format is AT[+ &]<command>=?, e.g.: AT+CMGL=? 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></ERROR>[ERROR INFO]<CR><LF> Returned of AT Commands The following describes AT commands and returned descriptions supported by the module: AT command returned format: --<CR><LF><Character strings relating to AT commands><cr><lf> --An exceptional case: e.g.: AT+ZPOWEROFF (response format) directly return with AT command status report (, ERROR): --If there is error in AT command format, Error will return; --If AT command executes successfully, will return AT Command 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 bps. 7
