  • Page 67: Operation

    Operation Operation The XBee 868LP RF Module uses a multi-layered firmware base to order the flow of data, dependent on the hardware and software configuration you choose. The following configuration block diagram shows the host serial interface as the physical starting point and the antenna as the physical endpoint for the transferred data.

  • Page 68: Single Frequency Mode Band Mode

    For example, if you enabled two channels you would have an effective duty cycle of 5.6%. The XBee 868LP RF Module uses a sliding bucket algorithm to calculate usage over the period of 1 hour for each channel. Each bucket accumulates for 6 minutes.

  • Page 69: Spi Communications

    Serial communications For serial communication to occur, you must configure the UART of both devices (the microcontroller and the XBee 868LP RF Module) with compatible settings for the baud rate, parity, start bits, stop bits, and data bits. Each data byte consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit (high).

  • Page 70: Spi Operation

    SPI implementation The XBee 868LP RF Module operates as an SPI slave only. This means an external master provides the clock and decides when to send. The XBee 868LP RF Module supports an external clock rate of up to 3.5 Mb/s.
  • Page 71 UART operation. Full duplex operation SPI on the XBee 868LP RF Module requires that you use API mode (without escaping) to packetize data. By design, SPI is a full duplex protocol even when data is only available in one direction. This means that when a device receives data, it also transmits and that data is normally invalid.

  • Page 72: Configuration Considerations

    Sleep modes generally work the same on SPI as they do on UART. However, due to the addition of SPI mode, there is the option of another sleep pin. By default, Digi configures DIO8 (SLEEP_REQUEST) as a peripheral and during pin sleep it wakes the device and puts it to sleep. This applies to both the UART and SPI serial interfaces.

  • Page 73: Spi Parameters

    Clock polarity (CPOL): first (leading) edge rises All XBee 868LP RF Modules use SPI mode 0 and MSB first. Mode 0 means that data is sampled on the leading edge and that the leading edge rises. MSB first means that bit 7 is the first bit of a byte sent over the interface.

  • Page 74: Cts Flow Control

    If the device sends data out the UART when RTS is de-asserted (set high) the device could send up to five characters out the UART port after RTS is de-asserted. Serial interface protocols The XBee 868LP RF Module supports both Transparent and Application Programming Interface (API) serial interfaces. Transparent operating mode When operating in Transparent mode, the devices act as a serial line replacement.

  • Page 75: Comparing Transparent And Api Modes

    API frames can provide indication of I/O samples from remote devices, diagnostics and node identification messages. Remote Configuration Set/read configuration commands can be sent to remote devices to configure them as needed using the API We recommend API mode when a device: XBee 868LP RF Modules User Guide...
  • Page 76 If the conditions listed above do not apply (for example, a sensor node, router, or a simple application), then Transparent operation might be suitable. It is acceptable to use a mixture of devices running API mode and Transparent mode in a network. XBee 868LP RF Modules User Guide...

  • Page 77: Modes Of Operation

    Modes of operation Modes of operation The XBee 868LP RF Module is in Receive Mode when it is not transmitting data. The device shifts into the other modes of operation under the following conditions: Transmit Mode (Serial data in the serial receive buffer is ready to be packetized)

  • Page 78: Transmit Mode

    Receive mode This is the default mode for the XBee 868LP RF Module. The device is in Receive mode when it is not transmitting data. If a destination node receives a valid RF packet, the destination node transfers the data to its serial transmit buffer.
  • Page 79 Any changes you make to the configuration command registers using AT commands do not take effect until you apply the changes. For example, if you send the BD command to change the baud rate, the actual baud rate does not change until you apply the changes. To apply changes: XBee 868LP RF Modules User Guide...

    This results in all nodes repeating the transmission four times as well. In order to avoid RF packet collisions, the network inserts a random delay before each router relays the broadcast message. You can change this random delay time with the NN parameter. XBee 868LP RF Modules User Guide...

    When synchronized, a device in Normal mode relays sync messages that sleep-compatible nodes generate, but does not generate sync messages itself. Once a device in Normal mode synchronizes with a sleeping network, you can put it into a sleep- compatible sleep mode at any time. XBee 868LP RF Modules User Guide...

    When a device has synchronized with the network, you can query its sleep and wake times with the OS and OW commands respectively.

    The device may be removed from the OEM PCB by the use of a hot air rework station, or hot plate. Be careful not to overheat the device. During rework, the device temperature may rise above its internal solder melting point and care should be taken not to dislodge internal components from their intended positions.
