4.9 AT+IPR Set fixed local rate
The command
AT+IPR
can be used to set or query the TE-TA interface bit rate.
Syntax
Command Description
The test command returns the values of the supported automatically detectable bit rates and the values of the
supported fixed bit rates.
The read command returns the current bit rate of the interface.
The write command specifies the bit rate to be used for the interface. When you set a fixed rate, make sure that
both TE (DTE) and TA (DCE) are configured to the same rate.
The setting is stored in the non-volatile memory and will be used when the ME is powered up again. However,
in case of autobaud mode (
AT+IPR
=0) the detected TA bit rate will not be saved and, therefore, needs to be
resynchronized after restarting the ME (see Section 4.9.1 , Autobauding ).
Parameter Description
bit rate per second (bps)
0
Activates autobauding. Not supported on ASC1. Not usable with Java. See
Section 4.9.1 , Autobauding for further details.
