Chapter 2 – Configuration Commands The parameter can only be used if the serial interface is enabled. Due to the command syntax, you need to enter parameter , followed by , where is only a placeholder and has no effect. See examples below. 0 Placeholder for as stated above. Default. 1 ME resets and restarts to full functionality. After reset and restart, PIN 1 authentication is necessary (AT+CPIN). If autobauding is enabled, it is recommended to wait 3 to 5 seconds before entering the first AT command. For details on autobauding refer to Section 4.9.1, Autobauding. Unsolicited Result Codes: URC 1 ^SYSSTART Indicates that the ME has been started and is ready to operate. If autobauding is active (AT+IPR=0), the URC is not generated. If the ME is configured to enter the Airplane mode after restart or reset the following URC is received on bootup: “^SYSSTART AIRPLANE MODE”. In this mode, only the AT commands listed in Section 20.4, Availability of AT Commands Depending on Operating Mode of ME can be used. For details please refer to the AT^SCFG command, parameter . Notes: • When a circuit-switched call is in progress, =7 or 9 can be activated without terminating the call. However, setting =0, during a circuit-switched call immediately disconnects this call. • To check whether power saving is on, you can query the status with the read command AT+CFUN only if the module is in full functionality mode or in CYCLIC SLEEP mode. If available, you can also take advantage of the status LED controlled by the SYNC pin (see AT^SSYNC and [2]). With AT^SSYNC you can select different modes of LED signalization during SLEEP modes (See Section 18.6.1., ME Status Indicated by Status LED for details. However, the module can wake up temporarily from power saving without leaving its CYCLIC SLEEP mode (without changing +CFUN “”); e.g., for a network scan after a loss of radio coverage, or after receipt of serial data during CYCLIC SLEEP mode. During this “temporary wakeup state” the LED will operate as if the ME was in full functionality mode. • Recommendation: In NON-CYCLIC SLEEP mode, you can set an RTC alarm to wake up the ME and return to full functionality. This is a useful approach because, in this mode, the AT interface is not accessible. 2.9.1 Wake up the ME from SLEEP Mode A wake-up event is any event that causes the mobile equipment (ME) to draw more current. Depending on the selected mode, the wake-up event either switches the SLEEP mode off and takes the ME back to full functionality AT+CFUN=1, or activates the ME temporarily without terminating the selected SLEEP mode. Definitions of the state transitions described in Table 2.3: • Quit: ME exits SLEEP mode. • Temporary: ME becomes active temporarily for the duration of the event and the mode-specific follow-up time after the last character was sent or received on the serial interface. • No effect: Event is not relevant in the selected SLEEP mode. The ME does not wake up. Table 2.3: Wake-up Events in NON-CYCLIC and CYCLIC SLEEP Modes Event Selected mode: =0 Selected mode: =7 or 9 Ignition line No effect No effect /RTS0 or RTS1 activation Quit Mode 7: No effect (RTS is only used for flow control) Mode 9: Temporary Unsolicited Result Code (URC) Quit Temporary Incoming voice or data call Quit Temporary Any AT command (incl. outgoing SMS, Not possible (UART disabled) Temporary voice or data call) Incoming SMS (AT+CNMI is set to 0,0 No effect No effect (this is the default setting) Incoming SMS (AT+CNMI is set to 1,1) Quit Temporary GPRS data transfer Not possible (UART disabled) Temporary RTC alarm line Quit Temporary AT+CFUN=1 Not possible (UART disabled) Quit Multi-Tech Systems, Inc.

Chapter 2 – Configuration Commands 2.10 AT^SMSO Switch off Mobile Station Description: AT^SMSO initiates the power-off procedure. High level of the module’s PWR_IND and the URC “^SHUTDOWN” notifies that the procedure has completed and the module has entered the POWER DOWN mode. Therefore, be sure not to disconnect the operating voltage until PWR_IND is High or until the URC “^SHUTDOWN” is displayed. Otherwise, you run the risk of losing data. For further details on how to turn off the module see the [2]. Exec Command Syntax: ^SMSO Response(s): ^SMSO: MS OFF, OK Test Command Syntax: AT^SMSO= Response: OK Unsolicited Result Code: ^SHUTDOWN Indicates that the power-off procedure is finished and the module will be switched off in less than 1 second. Notes: • Do not send any other AT command after AT^SMSO. • If AT^SMSO is entered on one of the Multiplexer channels, the ME closes the Multiplexer channels, terminates the Multiplexer, and deactivates all other functions. Then the URC “^SHUTDOWN” will be issued on the physical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with the Multiplexer driver. 2.11 AT+GCAP Request Complete TA Capabilities List Description: AT+GCAP returns a list of additional capabilities. Exec Command Syntax: AT+GCAP Response(s): +GCAP: , OK Test Command Syntax: AT+GCAP= Response: OK Parameter Description: e.g., +CGSM,+FCLASS Note: • +CGSM: The response text shows which GSM commands of the ETSI standard are supported. 2.12 AT+CMEE Mobile Equipment Error Message Format Description: AT+CMEE controls the format of the error result codes that indicates errors related to the Multi-Tech wireless modem’s functionality. Format can be selected between plain “ERROR” output, error numbers or verbose “+CME ERROR: ” and “+CMS ERROR: ” messages. Possible error result codes are listed in Table 2.6, General “CME ERROR” Codes (GSM 07.07), Table 2.5, GPRS related “CME ERROR” Codes (GSM 07.07) and Table 2.8, SMS related “CMS ERROR” Codes (GSM 07.05). In Multiplexer mode, the setting applies only to the logical channel where selected. The setting on the other channels may differ. Test Command Syntax: AT+CMEE= Response: +CMEE : (list of supporteds) OK Read Command Syntax: AT+CMEE Response: +CMEE : OK Write Command Syntax: AT+CMEE= Response: OK ERROR +CME ERROR: Multi-Tech Systems, Inc.
