How Does The XBee 3 Click Board™ Work?
The XBee 3 Click Board™ is based on the XB8X-DMUS-001, a Digi XBee® CE/RED certified RF module suitable for mission-critical wireless applications from Digi International. The XB8X-DMUS-001 can run a proprietary DigiMesh® or point-to-multipoint networking protocol utilizing a low-power Silicon Labs MCU and an ADF7023 transceiver with an integrated SAW filter offering industry-leading interference blocking. It also supports low-power sleeping nodes and has an RF line-of-sight range of up to 14km (rural range line of sight) in a combination of coverage, data redundancy, and data reliability.
The XB8X-DMUS-001 module is pre-certified for use in European countries. Operating between 863MHz and 870MHz (868MHz), it allows use in several regions, including approved European countries. It also leverages surrounding frequencies for LBT+AFA (Listen-Before-Talk and Adaptive-Frequency-Agility), significantly reducing interference by listening to the radio environment before any transmission starts and automatically shifting to a new channel when interference is detected.
The XBee 3 Click Board™ comes with a configurable host interface allowing communication with MCU using the chosen interface. The XB8X-DMUS-001 can communicate with MCU using the UART interface with commonly used UART RX, TX, and hardware flow control pins UART CTS and RTS (Clear to Send and Ready to Send) or using the SPI interface (XBee module will work as an SPI-slave only). In the case of the SPI interface, the users can use it to configure the module and write the library by themselves.
The XBee 3 Click Board™ is associated with many other features, such as the reset function and the possibility of visual and digital indicators. An active-low reset signal routed on the RST pin of the mikroBUS™ socket activates a hardware reset of the system, while a yellow LED indicator marked as ASSOC represents a visual indication of the module's connection to the network. If the LED is constantly on, it means that the module is not connected to the mobile network, while the case of standard flashing of the LED represents the normal operating mode.
The A/D pin routed on the INT pin of the mikroBUS™ socket represents a type of interrupt whose function can be selected by positioning an onboard SMD jumper to an appropriate position labelled as DTR or ATT. DTR position is a "Data terminal ready" function used to tell the XBee module that the host MCU is ready to communicate, while the ATT position (SPI Attention) represents an indicator for the SPI interface whenever the XBee module has data for the host MCU. In addition, the board also has a commissioning pushbutton marked as COMMI which, combined with an ASSOC LED, provides various simple functions to aid in deploying devices in a network.
The XBee 3 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
