AC75 AT Command Set

15.1 AT^SRSA

s

<dataForm>(num)

SAP message data format
[0]	XSAP ATC/URC format
	SAP messages are translated into ASCII coded strings and transmitted as
	parameters of the AT^SRSM command and the "^SRSM" URC. When using a
	Bluetooth modem with AT command interface for transmitting data, it is recom-
	mended to choose the XSAP data format. Note that AT commands not related
	to RSA shall not be used after RSA activation on the dedicated serial multi-
	plexer channel.
1	SAP transparent binary format
	SAP messages are transmitted as coded in the SAP specification. This data
	format should be selected for transmitting SIM data to a Bluetooth stack which
	is part of the application. The binary data will be exchanged transparently with
	the ME. However, the SAP data format does not need ASCII character conver-
	sion. As a result less data will be transferred and the SIM communication will
	be faster.
<beaconPer>(num)
Beacon period
0...[6]...100	Specifies the number of seconds the SAP client waits before sending the next
	CONNECT_REQ message. A 0 value leads to a one-time connection request.
	This parameter is applicable for SAP client activation only.
<discType>(num)
SAP disconnection type

This parameter is only applicable if <sapRole> equals 0.

Calls or active GPRS contexts via a remote SIM will be lost due to missing SIM access. Use of AT+CLCC is rec- ommended to query call states before RSA deactivation.

0	Hold SAP role
	SAP connection is going to be disabled. The AC75 remains in SAP mode and
	is ready to (re)establish an SAP connection. If an SAP connection was ongoing
	a URC "^SRSA: <devId>, <sapRole>, <connState>, <linkChange-
	Cause>" with <connState>= 0 is issued.
	• A server exclusively sends an SAP message DISCONNECT_IND (type
	"Graceful") to the client.
	• A client saves the SIM data temporarily held in the AC75's memory to the
	remote SIM and sends the DISCONNECT_REQ message to the server. If
	requested the client restarts sending CONNECTION_REQ messages. If a
	local SIM is attached the AC75 will use it to register to the network until a
	server offers its SIM again.
[1]	Stop SAP operation
	SAP connection is disabled and AC75 is forced to local SIM mode. A URC
	"^SRSA: <devId>, <sapRole>, <connState>, <linkChangeCause>" with
	<sapRole>= 0 and <connState>= 0 is issued.

• A server sends a DISCONNECT_IND message (type "Immediate") to the client and returns to local SIM mode immediately. SIM data temporarily held in the client's memory would be lost.

• A client exclusively sends the DISCONNECT_REQ message to the server. Without saving temporarily held data to a remote SIM or waiting for DISCONNECT_RESP the client immediately returns to local SIM mode.
