A.8.87 +SBDRT – Short Burst Data: Read Text Message
Exec Command:
+SBDRT
This command is used to transfer a text SBD message from the single mobile terminated buffer
in the A3LA-RS to the DTE. 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}
A.8.88 +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 A3LA-RS to the ESS does not clear the mobile originated
buffer.
Reading a message from the A3LA-RS does not clear the mobile terminated buffer.
Command Response:
0:
Buffer(s) cleared successfully
1:
An error occurred while clearing the buffer(s)
A.8.89 +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 A3LA-RS.
The MOMSN is maintained even after power cycle.
Command Response:
0: The MOMSN was cleared successfully
1: An error occurred while clearing the MOMSN
