4 Transparent / AT Firmware Transparent operation works “out of the box”Serial cable replacement3 Command Characters to enter Command mode (‘+++’ default)Simple configuration of network, addressing, and other advanced featuresRouterCoordinatorRouterEnd Device
5 API FirmwareCommands and data sent to the module through a simple API (Application Programming Interface)API frames expose simple and advanced ZigBee capabilitiesRouterCoordinatorRouterEnd Device
6 API Firmware XBee API Frames Transmit and Receive Frames Status Frames Simple Transmit and receive frames require only module addressesAdvanced transmit and receive frames expose ZigBee cluster IDs, endpointsTransmit status frames indicate the delivery status of the transmissionReceive frames indicate the sender’s addressStatus FramesIndicate device and network-level behavior including join indications, reset notifications, etc.

8 XBee - IO features UART Data Input (3.3V) 4 ADC’s 8+1 DIO lines PWM (RSSI) outputSupply voltage monitoring
9 XBee - ADC Analog to Digital Conversion XBee has 4 ADC’s 10 bit resolution1KHz MAX sample rateThe XBee does not have DAC’sOutput can be read from the UARTAlso can build a LPF for the PWM output
11 XBee - DIO line passing Digital Input / Output lines XBee has 8+1 DIO linesUser configurable forTimed samplingDefault statesChange DetectPass-through mode*Internal Pull-up enable/disable* firmware only
12 Xbee – Over the Air Using API mode it is possible To change configuration over the airSet/Reset and read IO linesRead A/D valuesXBee also can send you automatic low battery warning (voltage threshold)
13 Commissioning Pushbutton & Associate LEDs Note if you want to have the node rejoin on programmed ID and SC you need to power cycle after 4 button presses !!!
14 ZigBee Application Addressing In addition to 64- and 16-bit addresses, ZigBee supports endpoints, cluster IDs and profile IDs.ZigBee transmissions specify:Source and Destination AddressesSource and Destination EndpointsCluster IDProfile ID[Src 16-bit Addr] [Dest 16-bit Addr] [Src Endpoint] [Dest Endpoint] [Cluster ID] [Profile ID] [Payload]
15 Zigbee Profile IDsProfile IDs define a collection of devices and associated functions & services to provide an overall system level functionality.Example – a thermostat on one device talks with a heating element on another device. Both devices and their supported functions are defined in the same profile.Profile IDs can be private (defined and used solely by developer) or public (supported by multiple vendors).Public profiles include Home Automation, Smart Energy, etc.Private profiles include Digi’s profile, vendor X profileOne or more profile IDs may be defined on a device.Devices must communicate on the same profile ID to be interoperable.
16 Zigbee Cluster IDsCluster IDs are 2-byte values that define a particular action or service. e.g. – “Turn on Light”, “Read Sensor”.Cluster IDs are defined within the scope of a profile.“Action IDs”16
17 Zigbee EndpointsAn endpoint can be thought of as an application, a domain, or a TCP port.Each device must support one or more endpoints.

19 API ConstructionGraphic and unique slide for each 2min topic.19
20 API Explicit Tx Frame (0x11) Specify 64-bit address (16-bit optional)Data is delivered to the specified endpoint, cluster ID, and profile ID on the remote deviceCan send ZDO commandsGraphic and unique slide for each 2min topic.20
21 API Explicit Rx Frame (0x91) Indicates:Sender’s 64- and 16-bit addressesEndpoint, cluster ID, and profile ID informationGraphic and unique slide for each 2min topic.21
22 API A Note on Interoperability To talk to another ZigBee device...Set the profile ID, cluster ID, and destination endpoint and format the data payload correctly.
