Serial interfacing commands
The following AT commands are serial interfacing commands.
BD (Baud Rate)
Sets or displays the serial interface baud rate for communication between the device's serial port and
the host.
Modified interface baud rates do not take effect until the XBee Smart Modem exits Command mode or
you issue
AC (Apply Changes) . The baud rate resets to default unless you save it with WR (Write) or by
clicking the Write module settings button in XCTU.
The device interprets any value between 0x4B0 and 0x0EC400 as a custom baud rate. Custom baud
rates are not guaranteed and the device attempts to find the closest achievable baud rate. After
setting a non-standard baud rate, query
BD to find the actual operating baud rate before applying
changes.
Parameter range
Standard baud rates: 0x1 - 0xA
Non-standard baud rates: 0x4B0 - 0x0EC400
Note On XBee 3 Cellular firmware versions ending in *13 or earlier, the minimum baud rate is 2400
and the maximum is 230400.

NB (Parity)
Set or read the serial parity settings for UART communications.
