A.8.102 +IPR – Fixed DTE Rate
Set Command:
+IPR=<rate>[,<autoflag>]
Set the data rate at which the A3LA-RS will accept commands. The change in data rate takes
effect after the result code (e.g. OK) is received by the DTE.
<rate> takes the following values:
1
600 bps
2
1200 bps
3
2400 bps
4
4800 bps
5
9600 bps
6
19200 bps (default)
7
38400 bps
<autoflag> takes the following values:
0
Fixed rate – automatic rate adjustment is disabled
1
Automatic rate adjustment is enabled (default)
Read Command:
+IPR?
Query the current data rate and automatic rate adjustment setting. The response is in the form:
+IPR: <rate>,<autoflag>
Test Command:
+IPR=?
List the supported data rates. The response is in the form:
+IPR: (supported <rate>s),(supported <autoflag>s)
A.8.103 +SBDWT – Short Burst Data: Write a Text Message
Exec Command:
+SBDWT=[<text message>]
This command is used to transfer a text SBD message from the DTE to the single mobile
originated buffer in the A3LA-RS.
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 A3LA-RS will indicate to the DTE 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 DTE
Once the DTE receives the READY indication, the text message must be sent,
terminated by a carriage return
