XBee Tech Tip: Sending Serial Data From One XBee Wi-Fi to Another

Posted on: No Comments

This Tech Tip is brought to you by Digi Applications Engineer Mark Grierson. It is Part 1 in a 3-part series focusing on the XBee Wi-Fi module.

Be sure to answer the XBee Puzzler at the end of this entry for a chance to win an XBee Wi-Fi Development Kit!

In this tech tip, we are going to see just how easy it is to send serial data through from one XBee Wi-Fi radio module to another.

Setup

In order to complete this exercise, you’ll need:

  • 2  XBee  Wi-Fi(S6B) radio modules
  • 2 USB interface boards. These can be the development boards contained in the XBee Wi-Fi Cloud Kit, any XBIB-U or XBIB-U-DEV interface board, or any third party USB XBee interface board such as the Parallax XBee USB adapter board
  • PC (or Mac) running Next Generation XCTU

Procedure

Sending transparent serial data between 2 XBee Wi-Fi modules.

First we will need to connect 2 Wi-Fi Modules to a Wi-Fi access point that has access to the internet. For brevity, if you need assistance connecting you modules to an access point, please refer to the Quick Start Guide: XBee Wi-Fi Cloud Kit for assistance.

Note: For the purposes of this article, a basic understanding of XCTU is assumed. For specific help in working with XCTU please see the help section of the XCTU program.

  • Connect the radio modules to the PC using the interface boards and launch 2 instances of XCTU.
  • In each instance of XCTU connect to one of the XBee Wi-Fi modules:
    1. Click on the Add Radio icon
    2. Select the correct com port
    3. Ensure data settings are correct (Radio default is 9600, 8, N,1)
    4. Click Finish

  • Now click on the radio module in each instance of XCTU to read its settings.

  • Once you have the 2 instances of XCTU running, verify that the radios have received IP addresses from your DHCP server and then address each radio’s Destination IP address (DL) to match the Module IP Address (MY) of the other radio as shown below.

  • You will also want to ensure that the Device Options (DO) setting is set to 0. This will ensure that the serial data is not sent to the cloud.
  • Go to the “Consoles” mode of each XCTU by clicking the terminal icon at the top of XCTU.
  • Open the serial connection to the modules by clicking the “Open Serial Connection” icon on each XCTU instance.   The Icon will change to a connected status  and the background changes to green.
  • You can now type text directly into one of the console log screens and see it appear in red of the other consoles screen.

  • If you would rather send an entire string at once, this can be accomplished by creating a packet by clicking on the “Add New Packet” icon.   This packet builder also lets you select ASCII or Hex data to be sent.

Using the packet builder, you can create a series of serial strings to transmit from the radio.

Summary

As you complete this exercise, it will become apparent just how easy it can be to connect your XBee Wi-Fi module to any serial sensor or device and have that data sent to any other device connected to another XBee Wi-Fi module. Of course this is just a simple example of how transparent serial data can be transmitted around an XBee Wi-Fi network. XBee modules have many more advanced features including a full API mode to allow your applications to efficiently move data to any IP addressable device worldwide.

In our next issue we will demonstrate sending data back and forth between a host connected to an XBee Wi-Fi module such as XCTU and a non-XBee network client application on a local area network. Until then, have fun experimenting with all of the varied capabilities of these remarkable radio modules.

XBee Puzzler

Which statement best describes how a passive high gain antenna works?

  1. A high gain antenna adds energy to a radio to enhance its range.
  2. A high gain antenna does not add or subtract overall energy to a radio transmission, but rather focuses or re-shapes the radiation pattern in a certain direction.
  3. A high gain antenna removes energy from a radio’s radiation pattern.
  4. A high gain antenna has no effect on the range of a radio link

Submit your answer below. The deadline for entries is June 12, 2014. Three winners will be randomly selected from the correct submissions. Winners will be notified by email. Employees of Digi and its subsidiaries are not eligible for the prize drawing. Good luck!

This XBee Puzzler contest is now closed. The correct answer is: 2. A high gain antenna does not add or subtract overall energy to a radio transmission, but rather focuses or re-shapes the radiation pattern in a certain direction.

In this video, Digi’s Chief Innovator, Rob Faludi, shows you how easy it is to build a Wi-Fi enabled hardware prototype and develop an application for the Internet of Things with the XBee WiFi Cloud Kit. The kit wirelessly connects with Device Cloud by Etherios out of the box, so you can build custom widgets that interact with your cloud-connected hardware.

Interested in seeing more ideas of what is possible with the XBee WiFi Cloud kit? Check out the projects that came out of our employee Hackathon in Logroño.

Digi Delivers Live View of Pittsburgh’s Bald Eagles

Bald Eagles have returned to Pittsburgh after a long absence. Their return has received a large amount of attention as this is seen as a sign of the improved environment in the Pittsburgh area. The nest of the once endangered raptors sits on a steep bluff above the Monongahela River in Hays near Pittsburgh’s Southside.  PixController and the Pennsylvania Game Commission are streaming live video, so you can watch the eaglets grow up every day and at any hour. They even received a feature on NBC Nightly News, which you can watch below.

 
Digi teamed up with PixController to create a wireless solution that provides a 24-hour feed of the Hays Eagles. A Digi TransPort WR21 connected to Verizon’s 4G LTE network streams live audio and video to the organizations website, so thousands can check in and see what the eaglets are up to at anytime. The stream has already accumulated over one million views!

The Eagles hatched in early April and they’re growing quickly, so make sure you check out the live stream before they fly away. Click here to watch the live feed.

Digi helped build a similar solution for the Wildlife Research Institute to aid their study of bear hibernation. Read more about that project here.

UPDATE: The Germinator is Alive!

A couple weeks ago, we shared the projects our team in Logroño built for the Digi Employee Hackathon. Here is quick  update on ‘The Germinator Plus’ project. These pictures were taken two weeks after planting and as you can see, the project is in full force!

The Germinator Plus makes it easy to adjust the environment for different species of plants by using Device Cloud, XBee, a microcontroller, and sensors. The sensors monitor heat, light, and water levels and the system maintains the conditions needed for that species of plant. Read more about the project in the full Digi Employee Hackathon post.

The Next Generation of XCTU

You may have heard there is a new version of XCTU available. We rebuilt it from the ground up and added a number of new features. Now, you can graphically diagram your ZigBee networks all from within the XCTU interface. You can even perform tests to determine your XBee’s range with the built in range test. And for all the Mac users out there, we should mention that XCTU is now compatible with OS X! Here’s a quick demo of the software in the video below:

The next generation of XCTU will make building your ZigBee networks a breeze. Want to get started? Head over here to download the latest version of XCTU.
