MC55 AT Command Set s 1.5 Supported character sets 1.5 mobile Supported character sets The ME supports two character sets: GSM 03.38 (7 bit, also referred to as GSM alphabet or SMS alphabet) and UCS2 (16 bit, refer to ISO/IEC 10646). See AT+CSCS for information about selecting the character set. Character tables can be found below. Explanation of terms • IRA IRA means that one byte is displayed as two characters in hexadecimal format.

In this case, an escape sequence will be handled as normal characters.

MC55 AT Command Set s 1.6 Flow Control 1.6 mobile Flow Control Flow control is essential to prevent loss of data or avoid errors when, in a data or fax call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up. There are basically two approaches to regulate data flow: software flow control and hardware flow control.
PAGE 27
MC55 AT Command Set s 1.7 Unsolicited Result Code Presentation 1.7 mobile Unsolicited Result Code Presentation URC stands for Unsolicited Result Code and is a report message issued by the ME without being requested by the TE, i.e. a URC is issued automatically when a certain event occurs. Hence, a URC is not issued as part of the response related to an executed AT command. Typical events leading to URCs are incoming calls ("RING"), received SMs, changing temperature, status of the battery etc.

MC55 AT Command Set s 1.9 Errors and Messages 1.9 mobile Errors and Messages The final result codes "+CME ERROR: " and "+CMS ERROR: " indicate errors related to mobile equipment or network. The effect is similar to an ERROR result code. A final result error code terminates the execution of the command and prevents the execution of all remaining commands that may follow on the same command line. If so, neither ERROR nor OK result code are returned for these commands.

MC55 AT Command Set s 2.8 AT+CFUN 2.8 mobile AT+CFUN Set phone functionality This command serves to control the functionality level of the ME. It can be used to reset the ME, to choose one of the SLEEP modes or to return to full functionality. Intended for power saving, SLEEP mode reduces the functionality of the ME to a minimum and thus minimizes the current consumption.
PAGE 40
MC55 AT Command Set s 2.8 AT+CFUN mobile PIN ASC0 ASC1 MUX1 MUX2 MUX3 ! % % § § § Reference(s) GSM 07.07 Command Description The test command returns the values of the supported parameters. The read command returns the current functionality value. The write command can be used to reset the ME, to choose one of the SLEEP modes or to return to full functionality. Parameter Description (num) 0 NON-CYCLIC SLEEP mode: In this mode, the AT interface is not accessible.
PAGE 41
MC55 AT Command Set s 2.8 AT+CFUN mobile 8 CYCLIC SLEEP mode: In this mode, the serial interface is shortly enabled during paging. If characters are recognized on the serial interface, the ME stays active for 10 minutes after the last character was sent or received. ME exits SLEEP mode only, if AT+CFUN=1 is entered. To ensure that power saving takes effect immediately, the ME stays active for only 2 seconds after =8 was entered.
PAGE 42
MC55 AT Command Set s 2.8 AT+CFUN mobile to full functionality. This is a useful approach because, in this mode, the AT interface is not accessible. Examples EXAMPLE 1 To check the level of functionality use the read command: AT+CFUN? +CFUN: 1 Default mode after ME was restarted Remember that the AT interface is not accessible in NON-CYCLIC SLEEP mode. Consequently, the read command is only useful when the ME is set to full functionality or, when is set to 5, 6, 7, 8 or 9.
PAGE 43
MC55 AT Command Set s 2.8 AT+CFUN 2.8.1 mobile Wake up the ME from SLEEP mode A wake-up event is any event that causes the ME to draw current. Depending on the selected mode, the wakeup 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.

Please note that the SYNC pin may be assigned different functions: Depending on the design of the host application, the pin can either be used to indicate the current consumption in a transmit burst or to drive a status LED connected to the pin as specified in [2]. For detailed information on the SYNC pin and its LED functionality refer to [2]. PAGE 438 MC55 AT Command Set s 17.6 AT^SSYNC mobile of processing the signal. Your platform design must be such that the incoming signal causes other components to draw less current. In short, this allows your application to accommodate current drain and thus, supply sufficient current to the GSM engine if required. 1 LED mode: Enables the SYNC pin to drive a status LED installed in your application according to the specifications provided in [2]. The coding of the LED is described in Chapter 17.6.1. PAGE 439 MC55 AT Command Set s 18.
