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 !!! Digi API / AT ZigBee AF ZigBee ZDO ZigBee APS ZigBee Network MAC PHY

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 Router 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 Router Coordinator Router End Device

6 API Firmware XBee API Frames Transmit and Receive Frames Status 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 Advantages Disadvantage Disadvantages
Quick commands Additional information Over the air configuration Disadvantages Complex Not transparant Advantages Simple Transparant Streaming performance Disadvantage Slow for commands Not optimized for embedded systems

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. “Action IDs” 16

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 18

19 API Construction Graphic 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 device Can send ZDO commands Graphic and unique slide for each 2min topic. 20

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

23 ZigBee Feature Set Comparison
ZNet 2.5 ZB Self Healing Mesh Network X Source Routing Many to One Routing Extended PAN ID Low power end devices Mobile end devices AES 128-bit encryption Frequency Agility Interoperability with other devices Remote Configuration Commands

24 ZNet 2.5 & ZB (Zigbee PRO) ZigBee Alliance
ZNet 2.5: Designed for ZigBee ZB: ZigBee Certified (pending) Unicast Timeout (Hop Maximum) ZNet 2.5: Fixed Unicast Timeout ZB: Adjustable Unicast Timeout (12 sec.) Over-the-air firmware updates ZNet 2.5: not possible ZB: available

25 XBee Series - Summary XBee 802.15.4 XBee DigiMesh 2.4
FreeScale Chipset Ideal for applications 4 Antenna Options XBee DigiMesh 2.4 Ideal for MESH applications with ALL nodes sleeping XBee Znet 2.5 (not recommended for new designs) Ember EM250 Chipset Ideal for ZigBee Applications Xbee ZB Ideal for Zigbee Cross-Compliant Applications

26 Decision factors Do I need MESH ??? If NO: If YES:
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 (vector based) Automatic route discovery Self-healing Extended range – through mesh IF YES: XBee DigiMESH2.4 (Freescale based) Mesh support (peer-to-peer based)

27 XBee Platform Agility Shared footprint
Similar commands and interface (some exceptions) Future-proof footprint Considerable ongoing development Ability to change RF functionality quickly, without significant redesign.
