5.7.87 +SBDRT - Short Burst Data: Read Text Message from the Iridium
9523
Exec Command: +SBDRT
This command is used to transfer a text SBD message from the single mobile terminated buffer in the
Iridium 9523 to the FA. This command is similar to +SBDRB but does not provide a length indicator or
checksum. The intent of this command is to provide a human friendly interface to SBD for
demonstrations and application development. It is expected that most usage of SBD will be with binary
messages.
 Once the command is entered, the SBD message in the mobile terminated buffer is sent out of
the port.
 This command is similar to +SBDRB except no length or checksum will be provided.
 The maximum mobile terminated SBD message length is 1890 bytes.
 The mobile terminated message buffer will be empty upon power-up.
Command Response:
+SBDRT: <CR> {mobile terminated buffer}
5.7.88 +SBDD - Short Burst Data: Clear SBD Message Buffer(s)
Exec Command: +SBDD[<Delete type>]
This command is used to clear the mobile originated buffer, mobile terminated buffer or both.
 The <Delete type> parameter identifies which buffers are cleared.
0: Clear the mobile originated buffer
1: Clear the mobile terminated buffer
2: Clear both the mobile originated and mobile terminated buffers
 Using this command or power cycling the phone are the only means by which both buffers are
cleared.
 The mobile terminated buffer will be cleared when an SBD session is initiated.
 Sending a message from the Iridium 9523 to the ESS does not clear the mobile originated buffer.
 Reading a message from the Iridium 9523 does not clear the mobile terminated buffer.
Command Response:
0: Buffer(s) cleared successfully
1: An error occurred while clearing the buffer(s)
5.7.89 +SBDC - Short Burst Data: Clear SBD MOMSN
Exec Command: +SBDC
This command will clear (set to 0) the mobile originated message sequence number (MOMSN) stored in
the Iridium 9523.
 The MOMSN is maintained even after power cycle.
