INTRODUCTION Introduction This guide describes the AT commands: Hayes standard AT command set, in order to maintain the compatibility with existing SW programs. 3GPP TS 27.007 specific AT command and GPRS specific commands. 3GPP TS 27.005 specific AT commands for SMS (Short Message Service) and CBS (Cell Broadcast Service) Standard AT commands and proprietary AT commands help you control your product. Formatting Conventions Overview The following syntactical definitions apply: <...
INTRODUCTION The response to the test command (trailing =?) may change in the future to allow the description of new values and functions. Note: Issuing the read command (trailing ?) causes the command to be executed. Whether or not the equipment implements the action command (in this case issuing the corresponding test command ‐ trailing =? ‐ returns the OK result code), and, if subparameters are associated with the action, the ranges of subparameters values that are supported.
INTRODUCTION Avoid placing several action commands in the same command line. If one command fails, an error message is received. However, it is not possible to determine which command failed the execution.
INTRODUCTION Numeric form Verbose form 11 CONNECT 4800. 12 CONNECT 9600. 15 CONNECT 14400. 23 CONNECT 1200/75. Command Response Time‐Out If response codes are enabled, which is the default setting, then every command issued to the module returns a result response. The time needed to process the given command and return the response varies, depending on the command type.
INTRODUCTION Storing Values Set by Commands Overview Factory Profile And User Profiles The wireless module stores the values set by several commands in the internal, non‐volatile memory (non‐volatile memory), allowing to remember this setting even after power off. In the non‐volatile memory these values are set either as factory profile or as user profiles.
INTRODUCTION The values set by following commands are stored in the profile extended section and they depend on the specific AT instance. See +CMUX.
INTRODUCTION Stored by +CSAS command and restored by +CRES command. #SLED Note: Both commands +CSAS and +CRES deal with non‐volatile memory, intending for it either the non‐volatile memory and the SIM storage. Stored by #SLEDSAV command #VAUX Stored by #SKTSAV command and automatically restored at startup. #SKTRST command restores default values. #ESMTP #EADDR #EUSER #EPASSW Stored by #ESAV command and automatically restored at startup. #ERST command restores default values.
AT COMMANDS REFERENCE Format for Entering AT Commands This chapter describes the general format you must use when entering AT commands. Command Line Prefixes Starting A Command Line AT The prefix AT is a two‐character abbreviation for Attention. With one exception—the AT#/ prefix—you always use AT to start a command line that is sending commands from Terminal Equipment (TE) to Terminal Adapter (TA). Notes If you want to learn more about this command, refer to the 3GPP TS 27.007 specification.

CUSTOM AT COMMANDS Notes Settings are saved automatically in non‐volatile memory only if old or new mod is 2. Any change from 0 to 1 or from 1 to 0 is not stored in non‐volatile memory. The particular case AT#ENHRST=1,0 causes the module to immediately reboot. So if AT#ENHRST=1,0 follows an AT command that stores some parameters in non‐volatile memory, it is recommended to insert a delay of at least 5 seconds before to issuing AT#ENHRST=1,0.
CUSTOM AT COMMANDS Notes The alarm mode is indicated by status ON of hardware pin CTS and by status ON of pin DSR. The power saving status is indicated by a CTS ‐ OFF and DSR ‐ OFF status. The normal operating status is indicated by DSR ‐ ON. During the alarm mode the device does not make any network scan and does not register to any network. Therefore, the device cannot dial or receive any call or SM. The only command that can be issued to the module in this state is #WAKE.
CUSTOM AT COMMANDS 0 ‐ No action 1 ‐ Automatic shut‐down when the temperature is beyond the extreme bounds 2 ‐ RF TX circuits automatically disabled (using +CFUN=2) when operating temperature bounds are reached. When the temperature is back to normal the module is brought back to the previous state, before RF TX disabled. 4 ‐ The output pin is tied HIGH when operating temperature bounds are reached; when the temperature is back to normal the output pin is tied LOW.

AUDIO COMMANDS Notes If =1, the receiving of a DTMF tone is pointed out with an unsolicited message through AT interface in the following format: #DTMFEV: x with x as the DTMF digit Ensure the duration of a tone is not less than 50ms. The value set by command is not saved. A software or hardware reset restores the default value. To store the value in non‐volatile memory, use profiles. When DTMF decoder is enabled, PCM playing and recording are automatically disabled.
AUDIO COMMANDS #DVICFG: ,,< samplewidth >,, Test command reports the range of supported values for: ,,< samplewidth >,, Syntax Command Command type AT#DVIEXT=,[,[,[,>,[]]]] Set AT#DVIEXT? Read AT#DVIEXT=? Test Parameters and Values 0 1 0 1 0 Burst mode. Normal mode. Default: 1. Audio scheduler sample rate 8KHz. Default: 1.
AUDIO COMMANDS Miscellaneous Audio Commands PCM Play and Receive #SPCM Execute command allows user either to send speech sample coming from microphone and/or downlink audio channel to serial port, or to reproduce a PCM coming from serial port to speaker and/or uplink audio channel; both modes are also available during speech calls. Test command returns the supported range of values for and .
AUDIO COMMANDS Examples AT#SPCM=1,0,0 CONNECT +++ NO CARRIER Note: After CONNECT, 8Khz 8bit PCM stream has to be sent to serial port AT#SPCM=2,0,0 CONNECT +++ NO CARRIER Note: After CONNECT, 8Khz 8bit PCM stream can be read from serial port. TeleType Writer #TTY Set command enables or disables the TTY feature. Read command returns whether the TTY function is currently enabled or not, in the format: #TTY: Test command reports the supported range of values for .
