SAP message data format
[0]
XSAP ATC/URC format
SAP messages are translated into ASCII coded strings and transmitted as
parameters of AT command
AT^SRSM
and URC "
^SRSM
". If using a Bluetooth
modem with AT command interface for transmitting data, it is recommended 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 multiplexer chan-
nel.
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-
sation. As a result less data will be transferred and the SIM communication will
be faster.
Beacon period
Determines the period in seconds between sending the CONNECT_REQ messages. A 0 value leads to a one-
time connection request. This parameter is applicable for SAP client activation only.
0...[6]...100
SAP disconnection type
This parameter is only applicable if
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 TC63 remains in SAP mode and
is ready to (re)establish a SAP connection. If a SAP connection was ongoing
an URC "
^SRSA
: , , " with
= 0 is issued.
• A server exclusively sends a SAP message DISCONNECT_IND (type
"Graceful") to the client.
• A client saves SIM data which is temporarily held in TC63's memory to the
remote SIM and sends SAP message DISCONNECT_REQ to the server. If
requested the client restarts sending CONNECTION_REQ messages. If a
local SIM is attached the TC63 will use it to register to the network until a
server offers its SIM again.
[1] Stop SAP operation
SAP connection is disabled and TC63 is forced to local SIM mode. An URC
"
^SRSA
: , , " with = 0 and
= 0 is issued.
• A server sends a SAP message DISCONNECT_IND (type "Immediate") to
the client and returns to local SIM mode immediately. SIM data which is
temporarily held in client's memory would be lost.
• A client exclusively sends SAP message DISCONNECT_REQ to the
server. Without saving temporary held data to a remote SIM or waiting for
DISCONNECT_RESP the client returns to local SIM mode immediately.
