Changing the Baud Rate
The Wireless Bridge device is made up of two main components:
1.
The host processor
2.
XBee radio module
The host processor manages the USB interface, the information menu and communication to and from
the XBee radio module. Changing the device’s baud rate is a two-step process. In order to change the
baud rate successfully, the following steps must be followed
in order.
1.
Change the baud rate on the XBee module through the
data
COM port using AT commands or
the X-CTU program. Write the parameter to non-volatile memory.
2.
Change the Wireless Bridge device baud rate through the
information
COM port using the set
uart.rate command. Write to non-volatile memory using the set store command.
Example:
Changing the baud rate from the default 9600 to 115200 bps.
Step 1: Using the X-CTU program, the XBee radio module is discovered on the data port – in this case
COM43. The baud rate is changed to 115200. The “Write” button is used to store the setting.
