AT Command
The current version of the module only supports AT commands used to set the baud rate.
The default baud rate for this module's AT mode is 38400bps. For regular use, the default
baud rate is 9600.
Entering AT mode
• Using Arduino Serial Terminal and USB Xbee converter. You can download
Arduino IDE Here
• Place the module into AT Mode while powered off. Apply power to it and open the
corresponding com port in Arduino IDE's serial terminal. Set the Baud rate to
38400 and the setting next to that to "both NL & CR". You should now be able to
send AT commands to the Bluetooth bee.
