4.7 AT+IPR Set fixed local rate
The command
AT+IPR
can be used to set or query the DTE-DCE interface bitrate.
Syntax
Command Description
The test command returns the values of the supported automatically detectable bitrates and the values of the
supported fixed-bitrates.
The read command returns the current bitrate of the interface.
The write command specifies the bitrate to be used for the interface. When you set a fixed-rate, make sure that
both DTE (TE) and DCE (TA) are configured to the same rate. When you select autobauding, the DCE will auto-
matically 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. How-
ever, in case of autobaud mode (
AT+IPR
=0) the detected DCE bitrate will not saved and, therefore, will resyn-
