SAP connection state

No SAP connection established.
1
SAP connection ongoing, i.e. peers exchange messages.
Notes
• If
AT^SRSA
with
<dataForm>
set to 1 (SAP) is given on the same serial multiplex channel as specified with
parameter
<muxChan>
the SAP data transfer mode is entered immediately. Therefore no command response
is issued by the TC63 in this case.
• If the TC63 is acting as SAP client and has switched to a remote SIM it starts accessing this SIM. If during
this time AT commands are used which need access to the SIM itself (e.g.
AT+CPIN
?) the TC63 responds
with "+CME ERROR: SIM blocked" or "+CME ERROR: SIM busy". Retry until SIM is fully accessible in this
case.
• If the TC63 is acting as SAP server and has released its SIM to a client it considers it as not accessible. There-
fore AT commands which require SIM access will be rejected with "+CME ERROR: SIM not inserted".
• Parameters
<muxChan>
,
<dataForm>
and
<beaconPer>
are applicable for RSA activation only.
