5.5 +IPR–Set Fixed Data Rate

5.5.1 Command Syntax

Command
+IPR[=<rate>]
+IPR?
+IPR=?

5.5.2 Description

This numeric extended-format parameter specifies the data rate at which the DCE will
accept command set. It may be used to select operation at rates at which the DCE is
not capable of automatically detecting the data rate being used by the DTE. The
default value is 115200 bps.
If <rate> is not included in the command, the baud rate will be set to 115200bps.
The settings will be stored in NV automatically, and will be restored from NV when
power on.
Notes:

5.5.3 Defined Values

<rate>: valid numeric values, bps
600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400

 The auto detectable rates are not support currently, the interface is reserved for extended
use, so the first parameters of the TEST command will return brackets without value.
 If the UART baud rate is higher than the radio bearer rate, and the transmit data rate is high,
the data may be lost.
