10.8.1Description
Specifies the data rate at which the DCE accepts commands on the UART interface. The full range of data
rates depends on HW or other criteria.
SARA-R4 / SARA-N4
The command is not applicable on the USB interface and the DCE returns an error result code if the
command is issued.

10.8.3Defined values
Parameter Type Description
<rate> Number Allowed baud rates expressed in b/s (0, if present, means autobauding):
SARA-R404M / SARA-R410M-01B - 9600, 19200, 38400, 57600, 115200 (default and
factory-programmed value)
SARA-R410M-02B / SARA-R410M-52B / SARA-R410M-63B / SARA-R410M-73B /
SARA-R410M-83B / SARA-R412M / SARA-N4 - 9600, 19200, 38400, 57600, 115200
(default and factory-programmed value), 230400, 460800
SARA-R410M-02B
On SARA-R410M-02B-00 allowed baud rates are: 9600, 19200, 38400, 57600,
115200 (default and factory-programmed value).
10.8.4Notes
On the UART AT interface, after the reception of the "OK" result code for the +IPR command, the DTE
shall wait for at least 100 ms before issuing a new AT command; this is to guarantee a proper baud rate
reconfiguration.
