2.45 AT+IPR Set fixed local rate
Test command
AT+IPR=?
Response
+IPR:
(list of supported auto-detectable <rate>s), (list of supported fixed-only
<rate>s
) OK
Parameter
See write command
Read command
AT+IPR?
Response
+IPR: <rate> OK
Parameter
See write command
Write command
AT+IPR=<rate>
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
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 2.45.1).

In order to account for greater amounts of data it is recommended to choose a
minimum bit rate of 2400 bps. If the ME is operated in Multiplex mode we suggest
a minimum bit rate of 4800 bps.

Note
Factory setting is <rate>=0. It cannot be restored with AT&F. The current setting
will be preserved when you download new firmware or when the ME is powered
down.
