i have a portable device that consist of
arduino leonardo board,xbee series 2 as router( AT mode ) and different sensors.This portable device acts as a remote device and can be used upon power up.
The other side, i have a host controller that consist of arduino uno board, arduinoxbee shield v1.1, and xbee series 2 as coordinator( AT mode ). This host controller is plug through USB into my PC.
The aim of my project is to send the sensor data from the portable device using xbee wirelessly over to my host controller and displaying out on the arduino serial monitor.
I've managed to configured the two xbees. But now, i'm unsure of how im going to transmit and receive the data. I need a transmitter and receiver program for both xbees that is connected to the arduino. Anyone can help please?
There are a couple different options for how you can do this, but the simplest is to set up your sensor XBee either in change detect (IC) mode, or set a sample rate (IR). In either case you'll need to handle the RX Indicator frame at the controller, which will contain the sampled data.
I wrote a C# stack that can configure all this, but for what you're trying to do it would probably only be useful as a reference (https://github.com/jefffhaynes/XBee).

I'm trying to send and receive data between a board (Dialog DA14531) and a simulation application of a temperature sensor.
I can easily send and receive data between the board and my computer, using Termite for instance.
By using Com0Com, I can receive the data sent from the sensor simulator in Termite as well.
However; I can't directly send data between this simulator and my board. I'm using Advanced Serial Port Monitor application and while the simulator states that the connection has been established, there seem to be nothing going on with this port.
Does someone have any idea about what might have caused the problem and how should I proceed for debugging?
So, I've figured out a new way to fix the issue:
Created a pair of virtual ports by using Com0COM.
Connected the simulator to one of these ports and Termite to the other one.
Connected the board to the system.
Used port forwarding in Termite to send the received data to the board.
This way, I can also monitor the data traffic between the board and the simulator.
I'm having an issue connecting a serial device to an embedded device I'm writing code for.
The device I am writing has two serial ports, an incoming from my laptop, and an outgoing to an external device.
When I connect both terminals to my laptop and view the data, I get exactly the data I am expecting.
When I connect my laptop to the external device directly, I am getting exactly what I expect, and a response.
When I connect the laptop and the external device to the embedded device I am working on, the laptop sends data to it, it receives it, it passes it on to the external device. This works as expected.
However, the external device doesn't send back the response.
If I send data to the external device from the embedded device, each new message I send allows it to send the original reply.
I know the first message got through correctly because the external device whirrs to live, and I know when it is sending the response by running and logic analyser on the tx/rx comms and viewing the traffic.
I considered that the embedded device is holding the rx line and preventing its transmission, but I don't see how that possible in the code. Also if that is the case it shouldn't work when I plug both lines into my laptop.
I also considered the DTR was not set high, but checked this and it appears to be set high.
Does anyone know a reason which would prevent a device from responding?
Note: When I say Serial Ports I am referring to the UART when referring to the embedded device. All device use a DB9 connector running RS232.
Edit: Operating System on laptop is Windows 10. Embedded device is a Atmega324p.
Edit 2: Did some more testing. It appears that it sometimes work and sometimes doesn't.
I have added an image which show a almost perfect signal of the response.
The blue section is a gap in the signal that shouldn't be there.
Ended up finding a solution.
The RTS line was held via the embedded device at 1.2v, while the Pc was holding it at 5.2v.
Pulling the RTS line up to 5v fixed the issue.
i have one query actually i have 3 xbees series2.
i want xbee 1 (sensor+xbee(end device)) and xbee 2 as coordinator,where XBee2 will be attched to MCU.
now i have xbee 3 which again ((sensor+xbee(end device)).
now i want to make xbee3 also to communicate with coordinator(Xbee2).
now i have kept the same pan ID of Xbee1 and xbee3 as like Xbee2.
and again i have set xbee1 and xbee3 destination address for the Xbee 2 .
now my question are
how do i program the MCU using eclipse environment for receiving both Xbee1 and Xbee3 data?
and i want to communicate all Xbees with UART communication means i want to read data using pin 2 and 3 of Xbee..is it possible??
can anyone provide me the code for developing this procedure???
thanks
This is a common scenario. Run the coordinator in API mode and the end devices (you may want to start with those nodes as routers, and figure out the "sleeping end device" details once everything else is working) in AT mode.
The "AT mode" devices with DH and DL set to 0 will just pass serial data to the coordinator, and the MCU can parse the API frames to determine which device sent the data. The MCU can also address requests to the other devices -- either Remote AT Commands or data to send out the serial port.
Write code for the MCU however you normally would. There's a portable ANSI C library available if that's your language of choice. It can parse the API frames for you and simplify communications on the network.
I just bought an XBee Wi-Fi S6B. (I was expecting it to be similar to the WiFly that can easily post sampled I/O data to a webpage.) I am going to hook two temperature sensors to the analog inputs. Note - there are no Arduinos in this project.
I have configured the XBee to send UDP packets to my computer on port 3054 (0xBEE) - I can see them using Netcat.
My question: Is there any existing software out there for Linux or the Raspberry Pi that can receive these packets and decode them? I'd rather not have to re-invent the wheel. I've searched extensively, but everything I found was for API mode with an arduino attached. I'm interested in just running the XBee with the two temperature sensors.
Many of the search results I've seen are for talking to another XBee connected to my computer via a serial port. I'd rather not buy an extra XBee, because my computer is already on the same network.
Here's a small program I just created to listen for XBEE UDP packets. It listens currently for one temperature sensor, but is easily configurable to add on other sensors.

I have successfully talked to the computer from an Arduino via serial USB port and I had the idea that I could make a keyboard or mouse with the arduino. Say I wanted to translate the computer's mouse 1 pixel to the left. What message would I have to send over the serial line in order to achieve this?
Google is a wonderful thing. "use arduino as mouse" returns 1.7 million hits. The third hit on the list takes you to the Arduino Playground for an example using the new Leonardo board.
Note:
The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.
Assuming you don't have that board, here is another site for some other specific boards and yet another that is log for a project including hardware and software for older boards.
Hope this helps (and is a better answer to the question).
You would have to reconfigure the USB interface chip to appear as a USB HID endpoint.
