It has the characteristics of modern security, standard-based, and global operation. It is widely used in home automation, intelligent energy, wireless sensor and industrial automation. XBee company Refers to the brand name of digi international equipment family. ZigBee company Is a sharing protocol, so chips and modules are available from many manufacturers. This kind of standardization is the key element of its value.
First of all, digi created an excellent implementation, one with the highest engineering quality, and fully passed the interoperability certification of ZigBee alliance. These basic elements are just the foundation. Standardized host interfaces facilitate fast, easy to understand configuration, control, and communication.
Users can choose a simple human-readable at command or a structured API for machine-to-machine interaction. These standard dimensions include a very small micro size that integrates the power of XBee into a module no bigger than a nail. Digi extends its security framework Trust fence On the module, including security guidance, security identification and confidentiality. Each module is user programmable, so it can support application logic, sensor input, power management and so on without additional microcontrollers.
Finally, there is the power of the digi XBee ecosystem. If a part of the project needs to be migrated to different communication protocols in the future, there is no need to change the module schematic diagram, shape factors, host interface or embedded program, which makes the change between standards very simple.
Let's take a closer look Digital XBee Understand how this happens. Based on advanced embedded technology, Digi Xbee 3 Provides additional design freedom through easy to add features and flexible wireless connections. Digi XBee 3 modules have advantages in all categories - size, weight and power. Micro form factor is ideal for compact and portable applications. Through the improved micropypthon programmability, whether it is processing sensor information, reducing power consumption, or using digi XBee 3 as the main processor of the device, it can be easily calculated at the network end.
Module architecture Digi Xbee 3 It can quickly activate and develop wireless connection with wide compatibility. The standard digi XBee host interface is retained to support backward compatibility, and SPI and other enhancements are added to provide additional flexibility.
Digi's tool chain consists of powerful hardware, mature firmware, remote update and management functions, creating a system you can rely on. Digi xbee3 module has built-in digi trustfence data security framework, identity and privacy functions. Trustfence uses more than controls to protect itself from new and evolving cyber threats.
XBee developers can access digi XBee tools, a set of tools that support the whole product life cycle and promote faster development at a lower cost. From initial development to system management of deployment, each stage is activated and guided by software, hardware and cloud system Added the value of digi XBee module.
Here is an introduction to the digi XBee tool suite. One nice thing about Xbee is it can do anything that ZigBee can do if you use the ZigBee version , but it also includes other protocol stacks in the same form factor and host interface. For example, the sub-GHz XBee radio allows you to have much longer range than a 2. The form factor deals with a common shape and pin configuration in the hardware.
It has a pin or pin socket depending on the hardware footprint you select , which takes up a very small amount of space on the circuit board. This configuration makes it easier for you to bring a new device into the market, because if the form factor is the same, the host interface is the same.
In other words, if a ZigBee mesh is appropriate for one application but you need an extended range, non-mesh protocol for another, you can use the same software to interface between the device and modem. The host interface API is another important part of Xbee. Lower frequencies require larger antennas to be effective but they also have greater penetrating power when it comes to transmitting through walls and barriers.
Protocol: This is the language that the device "speaks" when transmitting and receiving data. XBee modules are designed to communicate using a specific protocol, although certain devices can be made to use a different protocol by changing the firmware. Series 1 modules are designed to use This is great for networks which contain only a transmitter and a receiver or multiple receivers.
The Series 2 modules are set up for the ZigBee Mesh protocol which is a mesh network standard, this is great if you have a lot of 'nodes' that need to all talk to each other. Series 1 modules aren't capable of mesh networking and can't communicate with other devices running the ZigBee Mesh firmware, however, Series 2 modules are backwards compatible and can be firmware configured for point-to-point networking.
While this is closely tied to range, it isn't the only factor. This number is important to keep in mind when selecting an antenna for a device to ensure that you comply with your local radio communication laws. The power listed on this chart is the maximum output power and it can be adjusted in firmware in case you need to dial it back. Data Rate: The speed at which the device can communicate over the air will effect not only how much data you can push over the network at once, but also how reliably the device will communicate at long distance.
Slower transmission rates can be beneficial if your network spans a large distance, a fact exploited by the XSC line of devices. The speeds listed here are maximums and can be adjusted in firmware for several of these devices. Antenna: The type of antenna, if any, that the module comes equipped with. There are several things to keep in mind when it comes to selecting the proper antenna or antenna connector for your project. A chip antenna is small and easy to enclose, but it doesn't give the best gain.
A wire antenna is simple and effective but it's also not as small as the chip antenna and can be more difficult to incorporate into your design; For that reason, most new XBee modules feature a trace antenna instead. Trace or PCB antennas are made from conductive traces on the module itself and have performance comparable to wire antennas while taking up less space.
If you're building your wireless device into an enclosure it can be beneficial to attach an external antenna, this can be achieved either by U. FL is the type of connector often found on the wireless adapters in laptop computers and other small devices, routers and larger devices often have RPSMA connectors. Remember that whenever you add an external antenna to a device you change the gain of the transmitter, so be sure you stay in compliance with your local radio communication regulations.

Hello guys, Can Anyone Thank you This specification is a very modern, robust radio technology built on over 40 years of experience by IEEE.
Before transmitting, ZigBee listens to the channel. When the channel is clear, ZigBee begins to transmit. This prevents radios from talking over one another, causing corrupted data. Or at least should! They wait for the other speaker to finish, and then talk. This ensures that the data bits are correct. Each packet is retried up to three times for a total of four transmissions. If the packet cannot get through after the fourth transmission, ZigBee informs the sending node so something can be done about it.
