9523

Exec Command: +SBDWT=[<text message>]

This command is used to transfer a text SBD message from the FA to the single mobile originated buffer

in the Iridium 9523.

The text message may be entered on the command line:

 For example, “AT+SBDWT=hello”

 The length of <text message> is limited to 120 bytes. This is due to the length limit on the AT

command line interface.

 The message is terminated when a carriage return is entered

Alternatively, the text message may be entered separately:

 Upon entering the command “AT+SBDWT”, the Iridium 9523 will indicate to the FA that it is

prepared to receive the message by sending the string “READY<CR><LF>” (hex 52 45 41 44 59

0D 0A) to the FA

 Once the FA receives the READY indication, the text message must be sent, terminated by a

carriage return

 The length of the text message entered in this way is limited only by the maximum mobile-

originated message length of 1960 bytes

 The mobile originated buffer will be empty upon power-up

 If any data is currently in the mobile originated buffer, it will be overwritten

Command Response:

For the “AT+SBDWT” form:

0 SBD message successfully stored in mobile originated buffer

period of 60 seconds.
