Introduction
Heads up! Originally, this tutorial was written to configure an XBee Series 1 to communicate in
transparency mode. However, this can apply to the XBee Series 3 module as long as you configure
the firmware to the legacy 802.15.4 protocol. For more information, check out the
and XCTU
tutorial.
The
XBee Shield
gives your Arduino a seamless interface to
wireless platforms around. With XBee, instead of being tied down by a serial cable -- inches away
from a paired device -- your Arduino can pass data over the air to another device hundreds of feet
away.

- Page 4 Covered In This Tutorial The goal of this tutorial is to set up wireless XBee communication between a computer and an Arduino/XBee Shield combo. Then, using a terminal program, we can remotely send data to an Arduino, or read data off of it.
- Page 5 XBee Buying Guide. Heads up! While this tutorial was written for XBee Series 1, you can still follow along using XBee Series 3 modules. Just make sure to configure it with the 802.15.4 (Series 1) firmware. For more information, check out the Exploring XBees and XCTU tutorial.
- Page 6 Exploring XBees and XCTU March 12, 2015 How to set up an XBee using your computer, the X-CTU software, and an XBee Explorer interface board. Favorited Favorite That tutorial will introduce you to XCTU and explain how to configure XBee networks and addresses.
- Page 7 Below we'll go more in-depth on the most important components of the shield. UART/Software Serial Switch One of the most important components on the XBee Shield is the DLINE/UART switch. This switch controls which Arduino pins interface with the XBee.
- Page 8 There's also a chance that, during program upload, spurious -- even harmful -- data might be sent to any device attached to the Arduino's hardware UART. So to avoid any problems that might arise from connecting the XBee to the Arduino's hardware UART, we usually take advantage of the...

- Page 13 To use re-define the software serial pins on an Arduino Mega 2560 or Arduino Leonardo, you would just need to comment out the line where it says: SoftwareSerial XBee(2, 3); // RX, TX and uncomment out the line here: //SoftwareSerial XBee(10, 11); // RX, TX Reroute Pins To reroute the pins, on an Arduino Mega 2560 or Leonardo, you would need to remove the solder jumper and reroute pads to the respective pins.
- Page 14 Warning for Users NOT Using the Arduino Serial Monitor! If you are using Digi's X-CTU or a serial terminal to configure or connect to an XBee by using a RedBoard/Arduino Uno as a serial passthrough, you may need to add a jumper wire between the RST and 5V pin to prevent the Arduino from resetting.

- Page 16 Example: Remote Control Arduino Setting up a chat system is fun, but where XBees and the XBee Shield really shine is in passing data to and from an Arduino, so you can remotely control it or receive data from it. In this example, we'll create a simple serial interface, which can be used to set and read analog and digital pins.
