14.2AT^SXSM Extended SIM Access

AT^SXSM extends AT+CRSM with additional SIM commands.

All parameters of AT^SXSM are used as specified by GSM 11.11 [21]. MC55 handles internally all required SIM interface locking and file selection routines.

MC55 may return error result code "+CME ERROR" if the command cannot be passed to the SIM, e.g. if no SIM is inserted. However, errors related to SIM action are reported in <sw1> and <sw2> parameters as defined in GSM 11.11 [21].

Parameter Description

<command>(num)

136	RUN GSM ALGORITHM
	Start the authentication mechanism and cipher key generation on the SIM. It
	runs the algorithms A3 and A8 using a 16 byte random number and the sub-
	scriber authentication key Ki, which is stored in the SIM.

<fileID>(num)

Identifier for an elementary data file on SIM, if used by <command>.

<P1>(num)

Parameter to be passed on by the MC55 to the SIM.

<P2>(num)

Parameter to be passed on by the MC55 to the SIM.

<P3>(num)

Parameter to be passed on by the MC55 to the SIM.

<data>(str)

If <command>=136 (RUN GSM ALGORITHM): 16 byte random number.
