  • Page 19: Xbee/Xbee-Pro Module Operation

    XBee/XBee-PRO module operation The XBee module provides a serial interface to an RF link. The XBee module converts serial data to RF data that is sent to any device in an RF network. In addition to RF data communication devices, the XBee module provides a software interface for interacting with a variety of peripheral functions, including I/O sampling, commissioning and management devices.

  • Page 20: Serial Communications For The Xbee Rf Module

    The XBee-PRO RF Modules interface to a host device through a logic-level asynchronous serial port. Through its serial port, the module can communicate with any logic and voltage compatible UART, or through a level translator to any serial device (for example, through a Digi proprietary RS-232 or USB interface board).

    XBee device placement For a network installation to be successful, the installer must be able to determine where to place individual XBee devices to establish reliable links throughout the network. Link testing A good way to measure the performance of a network is to send unicast data through the network from one device to another to determine the success rate of many transmissions.

  • Page 30: Xbee Device Discovery

    XBee device discovery Network discovery The network discovery command can be used to discover all Digi modules that have joined a network. Issuing the ND command sends a broadcast network discovery command throughout the network. All devices that receive the command will send a response that includes the device’s addressing information, node identifier string (see the NI command), and other relevant information.

    DigiMesh modules can be configured to act as routers or end devices with the CE command. By default all modules in a DigiMesh network act as routers. Modules configured as routers actively relay network unicast and broadcast traffic as described below. XBee/XBee-PRO DigiMesh 2.4 User Guide...

    DigiMesh modules utilize direct-sequence spread spectrum modulation and operate on a fixed channel. There are 16 operating channels defined in the 2.4 GHz frequency band. XBee modules support all 16 channels and XBee-PRO modules support 12 of the 16 channels. The operating channel on a module is selected using the CH command.

  • Page 42: Xbee Digimesh 2.4 Transmission Timeouts

    XBee DigiMesh 2.4 transmission timeouts When a node receives an API TX Request (API configured modules) or an RO timeout occurs (modules configured for Transparent Mode) the time required to route the data to its destination depends on a number of configured parameters, whether the transmission is a unicast or a broadcast, and if the route to the destination address is known.

    After it fails a route discovery will be initiated and, upon completion of the route discovery, the data will be transmitted along the new route. The timeout associated with the entire operation can be estimated as follows: brokenRouteUnicast=BroadcastTxTime+NH*unicastOneHopTime+2*knownRouteUnicast XBee/XBee-PRO DigiMesh 2.4 User Guide...

  • Page 44: Xbee/Xbee-Pro Digimesh 2.4 Sleep Modes

    XBee/XBee-PRO DigiMesh 2.4 sleep modes A number of low-power modes exist to enable modules to operate for extended periods of time on battery power. These sleep modes are enabled with the SM command. The sleep modes are characterized as either asynchronous (SM = 1, 4, 5) or synchronous (SM = 7,8). Do not use asynchronous sleeping modes in a synchronous sleeping network, and vice versa.

  • Page 45: Asynchronous Cyclic Sleep Mode (Sm=4)

    (SM=5) is a slight variation on (SM=4) that allows the module to be woken prematurely by asserting the Sleep_RQ pin (pin 9). In (SM=5), the XBee can wake after the sleep period expires, or if a high-to- low transition occurs on the Sleep_RQ pin.
