Questions tagged [xbee]

XBee is the brand name from Digi International for a family of form factor compatible radio modules. The first XBee radios were introduced under the MaxStream brand in 2005 and were based on the 802.15.4-2003 standard designed for point-to-point and point-to-multipoint communications at over-the-air baud rates of 250 kbit/s.

More information on XBee can be found on this Wikipedia article, where there also are many useful links (the excerpt was also taken from it).

What does it mean to "assert a pin"?

From the XBee/XBeePro product manual page 24 (link to pdf): Sleep Modes enable the RF module to enter states of low-power consumption when not in use. In order to enter Sleep Mode, one of the following conditions must be met (in addition to the…

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.

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…

Good RS232-based Protocols for Embedded to Computer Communication

I'm working on a project that involves a good bit of data communication between a remote Arduino and a computer. The wireless connection is through a pair of XBees, so we have a RS232 link between the Arduino and the computer. For small amounts of…

What is a good communicaton device among teensy and arduino besides "XBees"

I have been using XBees to communicate my teensies so far. However, as you know, XBees are really expensive and when I want multiple devices to communicate with each other, I have to pay for several teensies + several XBees, which come up to be…

Rather complicated sensor network

I was working on a project recently and it was the first one which was involved enough to make the sensor networking complicated. In the end, I think the communication was the bottleneck in terms of overall performance and I'm wondering how more…

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…

XBee short wire antenna replacement to longer wire?

Is it possible to extend the 1mW wire antenna XBees from the short wire antenna, to a longer wire antenna? Will this harm the output stage of the XBee? The point being that I have an XBee in a metal box and I need to place the antenna outside the…

Long range (~15 km) low baud-rate wireless communication in a mountain environment (no LOS)

I'm trying to implement a point-to-point communication system in a mountainous environment where the base station and the client are at least 15 km apart, without any line of sight (LOS). The base station could have more transmission and receiving…

How to connect RFduino to internet?

I backed the RFduino project on Kickstarter to use it in my next project. It is basically a tiny Arduino compatible board with built in Bluetooth LE that supports additional shields. I've also got a regular Arduino Uno with an Ethernet Shield. What…

Actual power consumtion of xbee series 2 in sleep/power down mode?

According to user manual and several other official documents from Digi, xbee in the power down/sleep mode can consume as low as 1uA. But somehow such a low power consumption seems simply unachievable on my hands. The following is my setup: the…

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…
