Questions tagged [zigbee]

ZigBee, formally described by IEEE standard 802.15.4, is an RF based wireless communications protocol aimed at short range networks that require moderate data rates and low power consumption. It allows ad-hoc connections and mesh networking to extend range while aiming to be cheaper and require less power than alternatives such as Wi-Fi.

What is XBee and how is it different from Zigbee?

It's easy to get an introductory explanation of Zigbee. Zigbee on Wikipedia Home networking with Zigbee Zigbee alliance But technical information on XBee seems harder to find. It's unclear to me what its similarities and differences to Zigbee are.

Communication between multiple microcontrollers

I'd like to start implementing a system consisting of N microcontrollers (N >= 2 MCUs), but I would like to know the possibilities to let them communicate one with the other. Ideally, (N-1) microcontrollers are placed inside the house acting as…

Simple and safe solution to control a power plug with Arduino or PC

What solutions are available to control a power plug (or even if possible a light socket), i.e. turning it On and Off? I have looked for xbee/zigbee solutions but there doesn't seem to be a solution available for European power sockets (and so few…

How does frequency affect the ability to traverse objects in RF transmissions?

Or perhaps, what are the best bands/modulations to choose from if I need to efficiently transmit data in a path with heavy metal obstacles? I need to build a number of devices to periodically transmit short bursts of data in a large storage facility…

ZigBee Light Link and XBee interoperability

With the release of new products like Philips Hue, which claim to support ZigBee Light Link, I would be interested if there is any way to use existing Xbee modules to communicate with them? Would it be possible to create a network using Digi's Xbee…

direct ZigBee communication with Philips Hue smart light bulbs

Philips Hue light bulbs use a Bridge(transmitter) to connect between your network and their smart lights via a ZigBee protocol called Light Link. Can you control the lights directly with your own xBee radio? I'm most interested in creating my own…

868 MHz frequency standard

I am wondering whether I am free to use any transmit/receive methods on this particular frequency or do I need to stick to some standards. I am willing to buy a chip with PHY layer of 868 MHz and we do have the software MAC provided with it ( it is…

XBee dropping packets and actual data rate lower than expected

I am transmitting continuously at 9600 bps using the default configurations for both my XBees XB24-B. The communication is one way only, the transmitter is connected to the ATMega328 UART and the receiver is connected to the PC via USB (FTDI). Here…

Xbee module , using X-CTU reset

I got this question and it might be really easy but its just something I have been wondering about I can't seem to be able to find the answer. When my baud rate in X-CTU isn't the same baudrate as my Xbee module, it asks for a reset of the Xbee…

ZigBee vs WiFi for wireless communication

I've been working on a product using WiFi. The reason I picked WiFi, is cause I essentially have 20-30 nodes communicating to a main node via a router. This all works very well, and its easy as its simple TCP/IP requests. However,the nodes sometimes…

Multiple xbees on same network

I have been looking at xbees recently but can't seem to find a tutorial on configuring and programming for 3 xbees on the same network - 1 to act as a master the other 2 respond as slaves, but the slaves will do separate functions such as one could…

Voltage divider for Xbee's ADC - what resistor values?

I have an analog sensor which outputs a value in range 0-3V depending on soil moisture. The Xbee's ADC requires a value between 0 and 1.2V. I was thinking about using a simple voltage divider: Where R1 would be twice as large as R2 thus giving me…
