Wireless Configuration with the Digi XBee Mobile App - XCTU for Mobile

Digi XBee® Mobile is an iOS and Android compatible app for connecting and configuring Digi XBee 3 devices using their new onboard Bluetooth. If you are familiar with Digi XCTU, you will immediately have a comfort level with the mobile version, which provides similar functionality.

The Digi XBee Mobile App helps commission, provision, activate, investigate and update your Digi XBee 3 radio modules wirelessly, with no physical access required. Once Bluetooth is activated, you can leave behind your heavy laptop, development board and USB cables. Going forward, your smartphone is all you'll need to manage your Digi XBee 3 radio module.

The XBee Mobile App is a member of the award-winning tool suite, Digi XBee Tools which collectively support rapid prototyping, development, configuration, testing, deployment and ongoing management, supporting the complete IoT application lifecycle.

Using the XBee Mobile App

In this hands-on guide, we'll show you how to use the mobile app version of Digi XCTU:

  • Look for and connect to nearby XBee 3 BLE devices.
  • Get basic information about the device and the firmware version it is running.
  • List all the configuration categories and settings of the firmware running in the XBee 3 device.
  • Read and change the value of any firmware setting.
  • Perform a remote reset of the device.

Configure the XBee 3 Zigbee Radio

Let's get our hands dirty with a Digi XBee 3 Zigbee radio module so you can see for yourself how easy and convenient it is to configure an XBee 3 from your smartphone or tablet with the XBee Mobile App.

Parts Needed

Note: All Digi XBee 3 modules are ready to run Bluetooth. Those with a PCB or Chip antenna require no further components. U.FL modules require an external 2.4 GHz antenna. RF Pad modules expect to be connected to an antenna at the board level. Digi XBee 3 Cellular modems require connecting an external 2.4 GHz Bluetooth antenna, in addition to the cellular LTE antenna normally used. Bluetooth can function even without these antennas, however range will be greatly reduced, so this is not recommended.

Activate Bluetooth

Before using the XBee Mobile App, youll want to activate Bluetooth on your Digi XBee 3 and assign it a password using the XCTU application on a Windows, MacOS or Linux computer.

Set up Digi XCTU

  • Download XCTU onto your computer and install it.
  • Mount an XBee 3 radio onto the XBIB evaluation board and connect it to the computer.
  • Launch XCTU and add a module, using the icon with the plus sign in the upper left, then selecting the appropriate port and baud rate.

  • Click on the radio module in the left column to select it. The modules configuration will be displayed in the right column.
  • Scroll down to the Bluetooth Options section to configure Bluetooth settings.

  • Set BT Bluetooth Enable to "Enabled (1)" and click the pencil icon to save that change to the radio module.
  • If a Bluetooth password has not been set, you will automatically be asked to configure it.

Install the XBee Mobile App

The XBee Mobile application is a free download for both Android and iOS. Download it onto your tablet or smartphone and launch the app to continue. Be sure to review the XBee Mobile App documentation. Once the app is installed with your XBee 3 radio module powered on, youre ready to connect.

Connecting to XBee 3

When you start the XBee Mobile app, it will search for all nearby Bluetooth-enabled XBee 3 radio modules.

Searching for devices

Password screen

When you have entered the correct password, the XBee 3 device configuration categories will be displayed. Notice that the module is identified by only its MAC address; the Name field is blank by default.

Using the XBee Mobile App

Entering a new setting is very easy. Lets give the XBee 3 a real name, so we can label it in a human-friendly fashion. For example, in a municipal street lighting application, we might give it a label like "Streetlight 476". Tap the Addressing category to see the current setup. Scroll down to Node Identifier, which is blank by default. Tap on this field to enter new text, typing in "Streetlight 476". Tap the Write button once you are done.

The information you entered in Node Identifier was saved to the XBee 3. It can be displayed in addition to the radio modules MAC address, making it easier to identify it wirelessly when many others are present. You will see this Node Identifier displayed inside the XBee Mobile application as "Name: Streetlight 476".

Useful Settings

There are a lot of settings to choose from. In many applications the factory defaults will be optimal. Its best to change only what you need to, though dont be afraid to experiment within your test environment. Its a great way to learn. Here are some you might want to look at first, since they are more frequently customized:

  • During initial configuration and commissioning of the radio module you may want to set the serial baud rate (UART category, BD Baud Rate), configure GPIO input and output pins (I/O Settings category), change the local API mode (UART category, AP API Enable), request Zigbee coordinator verification during join (Networking category, JV Coordinator Verification) and enable network encryption (Security category).
  • Sleeping the radio module will save energy, battery life and therefore also save money (Sleep Modes category). MicroPython scripts allow intelligent decision making to occur onboard the XBee 3 module, if you launch them automatically (MicroPython Options, PS MicroPython Autostart). See our series of MicroPython posts for more information.
  • In the field you can activate one Zigbee radio module to be a coordinator (Networking category, CE Device Role), request serial join verification notices (Networking, JV Join Verification) and see various diagnostic information, including the internal temperature (Diagnostic Commands, TP Temperature). And theres plenty more.
