OTAP Parameters
There is a set of parameters that control the OTAP procedures. These parameters can either
be set by AT command (AT^SJOTAP, refer to
[1]
during the production of the device, or by SM
(see
Section 8.4
) during operation of the device in the field. None of the parameters, which are
set by AT command, can be overwritten by SM.
•
JAD File URL: the location of the JAD file is used to install or update procedures. The JAD
file needs to be located on the net (e.g.
http://someserver.net/somefile.jad
or
http://
192.168.1.2/somefile.jad
).
•
Application Directory: this is the directory where a new application (JAD and JAR file) is
installed. The delete operation deletes this directory completely. When entering the appli-
cation directory with AT^SJOTAP or a short message ensure that the path name is not ter-
minated with a slash. For example, type "a:" or "a:/otap" rather than "a:/" or "a:/otap/". See
examples provided in
Chapter 6
.
•
http User: a username used for authentication with the http server.
•
http Password: a password used for authentication with the http server.
•
Bearer:
the
network
bearer
used
to
open
the
HTTP/TCP/IP
connection,
either
GPRS
or
CSD.
•
APN or Number: depending on the selected network bearer this is either an access point
name for GPRS or a telephone number for CSD.
•
Net User: a username used for authentication with the network.
•
Net Password: a password used for authentication with the network.
•
DNS: a Domain Name Server’s IP address used to query hostnames.
•
NotifyURL: the URL to which results are posted. This parameter is only used when the
MIDlet-Install-Notify attribute or MIDlet-Delete-Notify attribute is not present in descriptor.
There are parameters that can only be set by AT command:
•
SM Password: it is used to authenticate incoming OTAP SMs. Setting this password gives
an extra level of security.
Note: If a password set by AT command, all SMs must include this password
•
Ignore SM PID (TC65 only): when setting this the PID in received SMs is ignored.
•
Hide HTTP authentication parameters (TC65 only): this allows to hide the http authentica-
tion parameters in the at^sjotap read command and the otap tracer.
