8.3 OTAP Parameters

8.3OTAP 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.
