2.4.2.11 +IPR - fixed DTE interface rate
+IPR – fixed DTE interface rate
Execute command
Read command
AT+IPR? Returns the current value of +IPR parameter.
Write command
AT+IPR = <rate> Specifies the DTE speed at which the device accepts commands
during command mode operation, it may be used to fix the DTE-
DCE interface speed.
Parameter:
<rate> = 0/300/1200/2400/4800/9600/19200/38400/57600/115200
If <rate> is unspecified or set to 0, then automatic speed detection is enabled
and also character format (see +ICF) is set to auto-detect.
If <rate> is specified and not 0, DTE-DCE speed is fixed at that
speed, hence no speed auto-detection (autobauding) is enabled.
Test command
AT+IPR=? Returns the supported serial port speed list.
