3 XBee Module Thin API or AT interface application layer to , DigiMesh or EmberZNet stack Powerful feature set includes: –Remote configuration –Low power end devices –IO line set/read capabilities 8+1 GPIO (1 PWM) 4 A/D inputs –Network diagnostics 4 Antenna Options: Whip, Chip, U.FL, RPSMA No RF HW development risk Fully approved !!! PHY MAC ZigBee Network ZigBee APS ZigBee AF ZigBee ZDO Digi API / AT

4 Transparent / AT Firmware Transparent operation works “out of the box” Serial cable replacement 3 Command Characters to enter Command mode (‘+++’ default) Simple configuration of network, addressing, and other advanced features Coordinator Router End Device

5 API Firmware Commands and data sent to the module through a simple API (Application Programming Interface) API frames expose simple and advanced ZigBee capabilities Coordinator Router End Device

6 API Firmware XBee API Frames –Transmit and Receive Frames Simple Transmit and receive frames require only module addresses Advanced transmit and receive frames expose ZigBee cluster IDs, endpoints Transmit status frames indicate the delivery status of the transmission Receive frames indicate the sender’s address –Status Frames Indicate device and network-level behavior including join indications, reset notifications, etc.

7 AT versus API mode Advantages –Simple –Transparant –Streaming performance Disadvantage –Slow for commands –Not optimized for embedded systems Advantages –Quick commands –Additional information –Over the air configuration Disadvantages –Complex –Not transparant

8 XBee - IO features UART Data Input (3.3V) 4 ADC’s 8+1 DIO lines PWM (RSSI) output Supply voltage monitoring

9 XBee - ADC Analog to Digital Conversion XBee has 4 ADC’s 10 bit resolution 1KHz MAX sample rate The XBee does not have DAC’s –Output can be read from the UART –Also can build a LPF for the PWM output

10 XBee - DAC DAC PWM Pulse Width Modulation LPF

11 XBee - DIO line passing Digital Input / Output lines XBee has 8+1 DIO lines User configurable for –Timed sampling –Default states –Change Detect –Pass-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 air –Set/Reset and read IO lines –Read A/D values XBee 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 Addresses –Source and Destination Endpoints –Cluster ID –Profile ID [Src 16-bit Addr] [Dest 16-bit Addr] [Src Endpoint] [Dest Endpoint] [Cluster ID] [Profile ID] [Payload]

15 Zigbee Profile IDs Profile 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 profile One or more profile IDs may be defined on a device. Devices must communicate on the same profile ID to be interoperable.

16 Zigbee Cluster IDs Cluster 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.

17 Zigbee Endpoints An endpoint can be thought of as an application, a domain, or a TCP port. Each device must support one or more endpoints.

18 ZigBee Application Addressing – In a Nutshell Data flow for a received ZigBee RF data packet

19 API Construction

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 device Can send ZDO commands

21 API Explicit Rx Frame (0x91) Indicates: Sender’s 64- and 16-bit addresses Endpoint, cluster ID, and profile ID information

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.

25 XBee Series - Summary XBee –FreeScale Chipset –Ideal for applications –4 Antenna Options XBee DigiMesh 2.4 –FreeScale Chipset –Ideal for MESH applications with ALL nodes sleeping –4 Antenna Options XBee Znet 2.5 (not recommended for new designs) –Ember EM250 Chipset –Ideal for ZigBee Applications –4 Antenna Options Xbee ZB –Ember EM250 Chipset –Ideal for Zigbee Cross-Compliant Applications –4 Antenna Options

26 Decision factors Do I need MESH ??? If NO: –XBee (Freescale based) (point to multipoint) Slightly lower price than Series 2 Lower more predictable latency More predictable battery life If YES: Do I need ALL nodes to sleep (battery operated) and is it ok to have a proprietary Solution ? –IF NO: XBee Znet 2.5 / ZB (Ember based) –Mesh support –Mesh support (vector based) –Automatic route discovery –Self-healing –Extended range – through mesh –IF YES: XBee DigiMESH2.4 (Freescale based) –Mesh support –Mesh support (peer-to-peer based) –Automatic route discovery –Self-healing –Extended range – through mesh
