Get started with BLE
BLE (Bluetooth® Low Energy) is an RF protocol that enables you to connect your XBee device to
another device. Both devices must have BLEenabled.
For example, you can use your cellphone to connect to and configure your XBee device.
Enable BLE on an XBee device
This process explains how to enable BLEon your XBee3 device and verify the connection.
1. Set up your XBee device, and make sure to connect the BLE antenna to the device. See Get
started with the XBee Smart Modem Development Kit.
2. Enable BLEand configure the BLEpassword using XCTU.
3. Get the Digi XBeeMobile phone application.
4. Connect with BLEand configure your XBee device.
Note The BLE protocol is disabled on the XBee device by default. You can create a custom factory
default configuration that ensures BLE is always enabled. See Custom configuration: Create a new
factory default.
Enable BLEand configure the BLEpassword using XCTU
Some of the latest XBee3 modules support Bluetooth Low Energy (BLE) as an extra interface for
configuration. If you want to use this feature, you have to enable BLE. You must also enable security by
setting a BLE password on the XBee device in order to connect, configure, or send data over BLE.
The BLE password is configured using XCTU. Make sure you have installed or updated XCTU to version
6.4.2. or later. Earlier versions of XCTU do not include the BLEconfiguration features. See Download
and install XCTU for installation instructions.
Before you begin, you should determine the password you want to use for BLEon the XBee device and
store it in a secure place. Digi recommends a secure password of at least 8 characters and a random
combination of letters, numbers, and special characters. Digi also recommends using a security
management tool such as LastPass or Keepass for generating and storing passwords for many
devices.
Note When you enter the BLEpassword in XCTU, the salt and verifier values are calculated as you set
your password. For more information on how these values are used in the authentication process, see
BLE Unlock API - 0x2C.
