SAP connection state

No SAP connection established.

SAP connection ongoing, i.e. peers exchange messages.

Notes

• If

set to 1 (SAP) is given on the same serial multiplex channel as specified with

parameter

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.

?) 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

and

are applicable for RSA activation only.
