In this tutorial we will use two xBee series 1 modules with the Arduino uno board. We will configure them to act as a receiver and transmitter to control the brightness of an LED wirelessly by using one potentiometer. The xBee - series 1 - modules take the These modules allow a very reliable and simple communication between micro controllers, computers or other systems by using just a serial port!
They have also a 1mW wire antenna on them. They supports Point to point and multi-point networks.
Download the XCTU software from here. Now click on it first image above and set the CH field to e. These values must be the same to all xBee modules to communicate with each other. Now as this xBee will be our transmitter, set the CE field as "Coordinator".

If the baud rate isn't set to bps, change it to this value. Connect the explorer board with your computer again and follow the same procedure second image above but this time set the CE field as "End device". Try downloading the Codebender plugin and clicking on the "Run on Arduino" button to program your Arduino board with this sketch. And that's it, you've programmed your Arduino uno board with this sketch!
And here's the "xbee Receiver" code, connect the second Arduino uno board with your computer and press the "Run on Arduino " button. You have successfully completed one more "How to" tutorial and you learned how to fade an LED wirelessly by using the xBee S1 modules. Why an additional Arduino in the transmitter if XBee has its own pins. The receiver only passes the serial info on.XBee Basics - Lesson 4 - API mode: Reading analog data from remote XBee
Imagine an alarm system that sends a text message to you if the pin on the transmitter has changed its state after someone opened the door. Sorry my language. I translate my think from Google translator. Reply 7 months ago. Question 11 months ago on Introduction.
Exploring XBees and XCTU
Answer 7 months ago. I am doing something similar. Just one thing though, i cant seems to properly tweak the receiving coding to get another set of analog input to control another LED. One to control another.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I would like to send data temperature sensor that comes from the Ardunio XBee and receive it in my C programme. As tomlogic answered my question in Stack Overflow question XBee two-way communication sender and receiver at the same time.
Test the Arduino code with the built-in terminal in the Arduino IDE to see if the port actually can receive and send remove the XBee shield first.
After that works, test out the XBee communication. Learn more. Asked 7 years, 1 month ago. Active 1 year, 7 months ago. Viewed 8k times. For now, let's say I want to send 45, to my C programme. I don't receive any data that comes from the XBee shield. Am I missing anything with the code? None; port. One; port. Open ; Console. WriteLine "Sorry! ReadLine ; Console. Note: I tried mySerial. Is it possible to eliminate the XBee modules from your test setup, and just use a wired serial connection to verify that your serial code is working correctly?
You could also connect one or both of the XBee modules to X-CTU on a PC and verify that they're joined to the same network and passing data back and forth. Try to isolate the possible cause of the problem so you can focus your troubleshooting efforts.
Active Oldest Votes. I got it working. The problem was from my void loop method. The mySerial should be like mySerial. Your XBee shield uses pins 0 and 1 on the Arduino.

Does this mean that they are configured correclty? Then I wanted to connect an arduino to my receiver. You can see the code above. I am always getting no available data.
Returned -1 means that there is no data in the serial. Both XBees are connected to different arduino. XBees are correclty configured since I tested it I think I done it correctly. I am missing something, though. If they are working with FTDI, doesn't that mean that they are working correclty? And ATDL is the bottom bits of the destination. Can you help me on what is MY?
DL is the destination Low bits right? I took a quick look at the receiving XBee code and it appears that you read a character in a loop without checking to see if there is a character there to read.
Tutorial: Arduino and XBee Communication
You need to put a if xbee. See, there are no characters available so read returns a -1 and you get the error you're seeing. Or, did I miss something obvious? Quote from: PaulS on Jan 08,pm.The XBee Python Library provides the ability to communicate with remote nodes in the network, IoT devices and other interfaces of the local device. The communication between XBee devices in a network involves the transmission and reception of data.
Communication features described in this topic and sub-topics are only applicable for local XBee devices. Remote XBee device classes do not include methods for transmitting or receiving data. XBee modules can communicate with other devices that are on the same network and use the same radio frequency.
The XBee Python Library provides several methods to send and receive data between the local XBee device and any remote on the network. A data transmission operation sends data from your local attached XBee device to a remote device on the network.
The operation sends data in API frames, but the XBee Python library abstracts the process so you only need to specify the device you want to send data to and the data itself. You can send data either using a unicast or broadcast transmission. Unicast transmissions route data from one source device to one destination device, whereas broadcast transmissions are sent to all devices in the network.
Unicast transmissions are sent from one source device to another destination device. The destination device could be an immediate neighbor of the source, or it could be several hops away. This type of operation is blocking. This means the method waits until the transmit status response is received or the default timeout is reached. The XBeeDevice class of the API provides the following method to perform a synchronous unicast transmission with a remote node of the network:.
Protocol-specific classes offer additional synchronous unicast transmission methods apart from the one provided by the XBeeDevice object:. ACK of the command sent is not received in the configured timeout, throwing a TimeoutException. Other errors caught as XBeeException :. The default timeout to wait for the send status is two seconds. The XBee Python Library includes a sample application that shows you how to send data to another XBee device on the network.
The example is located in the following path:. Transmitting data asynchronously means that your application does not block during the transmit process. However, you cannot ensure that the data was successfully sent to the remote device. The XBeeDevice class of the API provides the following method to perform an asynchronous unicast transmission with a remote node on the network:. Protocol-specific classes offer some other asynchronous unicast transmission methods in addition to the one provided by the XBeeDevice object:.Track My Order.

XBees are hugely popular wireless transceivers for a number of reasons. They're flexible -- they send and receive data over a serial portwhich means they're compatible with both computers and microcontrollers like Arduino.
And they're highly configurable -- you can have meshed networks with dozens of XBees, or just a pair swapping data. You can use them to remotely control your robot, or arrange them all over your house to monitor temperatures or lighting conditions in every room.
The pair of XBees alone won't get you very far. In most cases you'll want a separate module to interface with the XBee. There are a variety of Explorer boards, all designed to achieve the same purpose: to create a communication gateway between your computer and the XBee. We're going to show you how to do all of that in this tutorial! XBees are really only useful if you have at least a pair of them.
They need buddies to talk to! Hence, there's a lot of "2x" in this list of materials. To follow along with this tutorial, you will need the following materials. You may not need everything though depending on what you have. Add it to your cart, read through the guide, and adjust the cart as necessary.
Don't know what XBees to start with? Try checking out our buying guide to compare the different modules. This tutorial builds on some lower-level electronics concepts. If you're not familiar with the subjects below, we recommend checking out those tutorials first. The first step to communicating with your XBee is picking an interface board that allows you to.
XBee Explorers act as a gateway between your computer and your XBee. There are a few to pick from, each offering their own, key differences. Here's a quick overview of each:.All of the sample applications are contained in the examples folder, organized by category. Every sample includes the source code and a readme.
This sample application shows how to get and set common parameters of the XBee device. Common parameters are split in cached and non-cached parameters. For that reason, the application refreshes the cached parameters before reading and displaying them.
The application then configures, reads, and displays the value of non-cached parameters. The application uses the specific setters and getters provided by the XBee device object to configure and read the different parameters.
For more information about how to manage common parameters, see Read and set common parameters. This sample application shows how to set and get parameters of a local or remote XBee device. Use this method when you need to set or get the value of a parameter that does not have its own getter and setter within the XBee device object.
The application then reads the parameters from the device to verify that the read values are the same as the values that were set. For more information about how to get and set other parameters, see Read, set and execute other parameters. For more information about how to reset a module, see Reset the device. For more information about this, see Open the XBee device connection. This sample application shows how to configure a Wi-Fi module to connect to a specific access point and read its addressing settings.
For more information about connecting to an access point, see Configure Wi-Fi settings. This sample application demonstrates how to obtain the XBee network object from a local XBee device and discover the remote XBee devices that compose the network. The example adds a discovery listener, so the callbacks provided by the listener object receive the events. For more information about how to perform a network discovery, see Discover the network.
This sample application demonstrates how to listen to network modification events. The example adds a modifications network callback, so modifications events are received and printed out. For more information about how to listen to network modifications, see Listen to network modification events. This sample application shows how to send data from the XBee device to another remote device on the same network using the XBee Python Library. In this example, the application sends data using a reliable transmission method.
Two Arduinos and two XBees. I want to send data from the one to another. The XBees communicate, because I have the proposes test connect one XBee with the Arduino and the other to the PC, write from the one, and watch the other in the other terminal.
Does this mean that they are configured correctly? Then I wanted to connect an Arduino to my receiver. You can see the code above. I am always getting no available data. Changing int to byte is really changing int to char. Negative one -1 in decimal is all ones in binary because int 's are signed by default.
All of that is to say that xbee. I was not able to find anything in the documentationbut I would assume that the -1 is due to an error based on the hardware Serial documentation.
This is because there is nothing to read. Until you have a working proof of concept, you should make it as simple as possible. Once it is working then add features one at a time. This seems like what you're doing already, but this could probably be simplified further cut the Arduinos out of the equation by using FTDI only, use hardware serial, etc.
I converted your int temp to unsigned char to handle MSB. It works for me.

But I used Xbee series 2 and hardware serial. Anyway, data handling is maters. Learn more. Asked 7 years, 9 months ago. Active 2 years, 9 months ago. Viewed 40k times. I am having the following: Two Arduinos and two XBees. I am using XBee series 1. They are configured through X-CTU, based on the one tutorial found on ladyada.
Returned -1 means that there is no data in the serial.
Peter Mortensen What Arduino board and version are you using? I tried arduino Uno to Uno and rduino Uno to micro. Active Oldest Votes. Trust me, it happens. Check to see if the XBee has data available prior to reading.
You'll get a lot less lines printed since it will wait until a byte is ready to be read. SoftwareSerial should work, but in my experience, hardware serial is much more reliable.
Simplify your effort as much as possible and then slowly add functionality.
