What’s interesting about XBee XBP24-BZ7WIT-004 module from Digi is the fact that it supports 2B which results in so many improvements regarding the power output as well as the data protocol of the Pro Series 2.
The basic idea behind creating this module is to enable complex mesh networks to be created depending on the XBee ZB ZigBee mesh firmware which therefore allows communication to occur among microcontrollers, systems, and computers and much more in an efficient and reliable way.
Note that point to point and multi-point networks are supported.
Note that the hardware configuration used in here is different than that used in previous modules, this means that they aren’t compatible with series 2.5 modules that are outdated, yet they can communicate with series 2 XBee modules.
