Xbee Programming¶

Very basic stuff. For more details, see the XBee manual or Brian Coltin Chris Mar.

In order to access this interface, plug an XBee dongle (with XBee) into a computer and open a terminal program.
Set your serial port to:

• BAUD rate 9600
• 8 data bits
• no parity
• 1 stop bit.

Sequence of Commands (press Enter after every command beginning with "AT")¶

• +++
• Wait for XBee to send "OK"
• AT**
• ATWR
• ATCN

• "+++" enters the XBee command mode
• "AT**" is one or more AT** commands to read and/or write setting on XBee
  • see below for useful/common examples
  • NOTE: any changes made will only be in effect until the XBee loses power unless you use ATWR
• "ATWR" writes any changes you made to the XBee's long-term memory to persist through power cycles
• "ATCN" exits the XBee command mode

Changing the BAUD rate¶

• ATBD (N)
  • Replace (N) with 3 for 9600 or 7 for 115200
  • You can omit (N) to read the current BAUD rate

Changing the Address (ID)¶

• ATMY (N)
  • Replace (N) with a hex value between 0 and FFFF (0 - 65535 decimal)
  • You can omit (N) to read the current address

Changing the Channel¶

• ATCH (N)
  • Replace (N) with a hex value between 0C and 1A (12 - 26 decimal)
  • You can omit (N) to read the current channel

Changing the PAN id (to create separate networks)¶

• ATID (N)
  • Replace (N) with the PAN id (in range 0x0000-0xFFFF)
  • You can omit (N) to read the current PAN

Reading the Firmware Version¶

• ATVR
  • XBee will respond with fimware version number
• ATVL
  • Verbose output (you probably don't need this)
