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.
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.
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.

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 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

• 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.
