OTAP Tracer

For easy debugging of the OTAP scenario, the OTAP procedure can be traced over the

serial interface. The trace output shows details of the OTAP procedure and the used

parameters. To enable the OTAP trace output use the at command at^scfg, e.g.

AT^SCFG=Trace/Syslog/OTAP,1

The serial interface on which you issue this command is then exclusively used for the OTAP

tracer. All other functionality which is normally present (AT commands or CommConnection

and System.out in Java) is not available when the tracer is on.

This feature is intended to be used during development phase and not in deployed devices.

8.10

Java Security as described in chapter 11 also has consequences for OTAP. If the module is

in secured mode the MIDlet signature is also relevant to the OTAP procedure. This means:

• if the application is a unsigned version of a installed signed version of the same

application then status code 910 is returned

• if the applications signature does not match the module's certificate then status code 909

is returned
