The length of the string parameters in the AT command is limited (see Table 6), the length in
the SM is only limited by the maximum SM length.
The minimum set of required parameters depends on the intended operation (see Table 6).
“optional/P” indicates that this parameter is only necessary when a POST result is desired.

Short Message Format
An OTAP control SM must use a Submit PDU with Class1, PID $7d and 8 bit encoding. As a
fallback for unusual network infrastructures the SM can also be of Class0 and/or PID $00.
The content of the SM consists of a set of keywords and parameter values all encoded in
ASCII format. These parameters can be distributed over several SMs. There is one single
keyword to start the OTAP procedure. For parameters that are repeated in several SMs only
the last value sent is valid. For example, an SM could look like this:
Install operation:
First SM:
OTAP_IMPNG
PWD:secret
JADURL:http://www.greatcompany.com/coolapps/mega.jad
APPDIR:a:/work/appdir
HTTPUSER:user
HTTPPWD:anothersecret
Second SM: OTAP_IMPNG
PWD:secret
BEARER:gprs
APNORNUM:access.to-thenet.net
NETUSER:nobody
NETPWD:nothing
DNS:192.168.1.2
START:install
Delete operation:
OTAP_IMPNG
PWD:secret
APPDIR:a:/work/appdir
START:delete
The
first

is
required:
it
is
used
to

an
OTAP
SM.
All
other
lines
are
optional
and
their
order
is
insignificant,
each
line
is
terminated
with
an
LF:
'\n' including the last one.
The
keywords,
in
capital
letters,
are
case
sensitive.
A
