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:

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><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:

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.

AT command returned format:

--<CR><LF><corresponding strings ><CR><LF>

--An exceptional case: e.g.: AT+ZPOWEROFF (response format) directly return with OK

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 ME3000 Module 1.2 GSM Glossary Abbreviations ADC AFC AGC ARFCN ARP ASIC BER BTS CDMA CDG CS CSD CPU DAI DAC DCE DSP DTE DTMF DTR EFR EGSM EMC EMI ESD ETS FDMA FR GPRS GSM HR IC IMEI ISO ITU LCD LED MCU MMI Definitions Analog-Digital Converter Automatic Frequency Control Automatic Gain Control Absolute Radio Frequency Channel Number Antenna Reference Point Application Specific Integrated Circuit Bit Error Rate Base Transceiver Station Code Division Multiple Access CDMA Development Group Coding Scheme Circuit Switched Data Central Processing Unit Digital Audio interface Digital-to-Analog Converter Data Communication Equipment Digital Signal Processor Data Terminal Equipment Dual Tone Multi-Frequency Data Terminal Ready Enhanced Full Rate Enhanced GSM Electromagnetic Compatibility Electro Magnetic Interference Electronic Static Discharge European Telecommunication Standard Frequency Division Multiple Access Full Rate General Packet Radio Service Global Standard for Mobile Communications Half Rate Integrated Circuit International Mobile Equipment Identity International Standards Organization International Telecommunications Union Liquid Crystal Display Light Emitting Diode Machine Control Unit Man Machine Interface 9 ME3000 Module Abbreviations MS PCB PCL PCS PDU PLL PPP RAM RF ROM RMS RTC SIM SMS SRAM TA TDMA TE UART UIM USB VSWR ZTE Definitions Mobile Station Printed Circuit Board Power Control Level Personal Communication System Protocol Data Unit Phase Locked Loop Point-to-point protocol Random Access Memory Radio Frequency Read-only Memory Root Mean Square Real Time Clock Subscriber Identification Module Short Message Service Static Random Access Memory Terminal adapter Time Division Multiple Access Terminal Equipment also referred it as DTE Universal asynchronous receiver-transmitter User Identifier Management Universal Serial Bus Voltage Standing Wave Ratio ZTE Corporation 10 ME3000 Module 2 AT Command 2.1 Common Command 2.1.1 A/: repeat previous command Description This command is used to repeat the previous command.
