Revision 2.6
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

period of 60 seconds.
