AT Command Set

2.46 AT+IPR Set fixed local rate

Test command Response
+IPR: (list of supported auto-detectable <rate>s), (list of supported fixed-only
AT+IPR=?
<rate>s ) OK
Parameter
See write command
Read command Response
+IPR: <rate> OK
AT+IPR?
Parameter
See write command
Write command
This command specifies the DTE-DCE bitrate. When you set a fix rate, make sure
that both DTE (TE) and DCE (= TA) are configured to the same rate. When you
AT+IPR=<rate>
select autobauding the DCE will automatically recognize the bitrate currently used
by the DTE.
A selected bitrate takes effect following the issue of any result code associated
with this command (e.g. OK).
The setting is stored in the non-volatile memory and will be used whenever the
engine is powered up again. However, in case of autobaud mode (+IPR=0) the
detected DCE bitrate will not be saved and, therefore, needs to be be re-
synchronized after restarting the GSM engine (see Chapter 2.46.1).
Response
OK or if error is related to ME functionality: ERROR / +CME ERROR: <err>
Parameter
<rate> bit rate per second
Reference Note
Your current setting of AT+IPR will be preserved
V.25ter
· when you download new firmware (i.e. a firmware update does not restore the
factory setting);
· in the event of power failure.
Generally, AT+IPR=x should be used as a standalone command. If nevertheless
combinations with other commands on the same line cannot be avoided, there are
several constraints to be considered:
· Avoid combinations with the AT commands listed in Chapter 1.4.2.
