The bottom hardware module mainly consists of a radio frequency (RF) module, a ZigBee wireless RF transceiver and a bottom control module. The ZigBee standard protocol defines two physical layer (PHY) standards, i.e. a 2.4 GHz physical layer and an 868 / 915 MHz physical layer. Both of the two physical layers are based on a direct sequence spread spectrum (DSSS) technology and use the same physical layer data packet format. The difference between the two physical layers lies in the working frequency, the modulation mode, the signal processing process and the transmission rate. The bottom control module defines the interface between the physical wireless channel and the MAC sub-layer, provides physical layer data services and physical layer management services. The physical layer data services receive and transmit data from the wireless physical channel. The physical layer management services maintain a database composed of physical layer related data.

The ZDO sub-layer responds to different requests of a remote device by opening and processing a target endpoint interface. Unlike other endpoint interfaces, the target endpoint interface is always opened at the start and is assumed to be bound to any incoming data frame sent to the port. The ZDC sub-layer provides standard ZigBee configuration services and defines and processes descriptor requests. A remote device can request any standard descriptor information through the ZDO sub-layer. When receiving these requests, the ZDO will call the configuration object to obtain the corresponding descriptor value. The APL layer provides high-level protocol stack management functions. The user application program uses this module to manage the protocol stack functions. The user application program mainly includes the application software pre-installed by the manufacturer. In order to provide more extensive applications for users, this layer also provides embedded APIs for instrument control, information appliances and communication devices, so that the interaction between the device and the user's application software can be more widely realized.
