  • Page 33: Serial Modes

    Modes Serial modes Serial modes The firmware operates in several different modes. Two top-level modes establish how the device communicates with other devices through its serial interface: Transparent operating mode and API operating mode. Use the AP command to choose Serial mode. XBee/XBee-PRO S2C 802.15.4 RF Modules use Transparent operation as the default serial mode.

  • Page 34: Command Mode

    Modes Serial modes protocol that allows you to direct data on a packet basis. It can be particularly useful in large networks where you need control over the operation of the radio network or when you need to know which node a data packet is from. The device communicates UART or SPI data in packets, also known as API frames.
  • Page 35 Modes Serial modes Both of these methods temporarily set the device's baud rate to 9600 and return an OK on the UART to indicate that Command mode is active. When Command mode exits, the device returns to normal operation at the baud rate that BD is set to. Send AT commands Once the device enters Command mode, use the syntax in the following figure to send AT commands.

  • Page 36: Transceiver Modes

    Modes Transceiver modes Make command changes permanent Send a WR (Write) command to save the changes. WR writes parameter values to non-volatile memory so that parameter modifications persist through subsequent resets. Send as RE (Restore Defaults) to wipe settings saved using WR back to their factory defaults. Note You still have to use WR to save the changes enacted with RE.

  • Page 38: Addressing

    Operation Addressing Addressing Every RF data packet sent over-the-air contains a Source Address and Destination Address field in its header. The XBee/XBee-PRO S2C 802.15.4 RF Module conforms to the 802.15.4 specification and supports both short 16-bit addresses and long 64-bit addresses. A unique 64-bit IEEE source address is assigned at the factory and can be read with the SL (Serial Number Low) and SH (Serial Number High) commands.
  • Page 39 Operation Encryption 802.15.4 protocol specifies eight security modes, enumerated as shown in the following table. Length of message integrity Packet length Level Name Encrypted? check overhead 0 (no check) MIC-32 MIC-64 MIC-128 0 (no check) ENC-MIC-32 ENC-MIC-64 ENC-MIC-128 Yes The XBee/XBee-PRO S2C 802.15.4 RF Module only supports security levels 0 and 4. It does not support message integrity checks.

  • Page 40: Maximum Payload

    Operation Maximum payload receiving device outputs a Receive Packet (0x81) frame for received data. These same rules apply for encryption if MM is 0 or 3. This is possible because the four-byte encryption App header includes the short address of the sender and the long received address is not used for API output. If encryption is enabled with MM of 1 or 2, then no App header exists, the source address is always long, and the receiving device in API mode always outputs a Description.

  • Page 41: Maximum Payload Summary Tables

    The sender is a XBee/XBee-PRO S2C 802.15.4 RF Module, and the receiver is a Legacy 802.15.4 module. The sender has the Digi Header enabled (MM = 0 or 3) and RR (XBee Retries) > 0. The sender sends broadcast and unicast messages at the same time to the Legacy 802.15.4 module without waiting for the transmission status of the previous packet.

  • Page 42: Networking

    Medium Access Control (MAC) Mode configures two functions: 1. Enables or disables the use of a Digi header in the 802.15.4 RF packet. When the Digi header is enabled (MM = 0 or 3), duplicate packet detection is enabled as well as certain AT commands.

  • Page 43: Xbee Retries Configuration

    Operation Networking The default value for the MM configuration parameter is 0 which enables both the Digi header and the MAC acknowledgment. XBee retries configuration Configures the maximum number of retries the device executes in addition to the three retries provided by the 802.15.4 MAC.

  • Page 45 Operation Networking By default, A1 is 0, which disables association and effectively causes an end device to operate in peer- to-peer mode. When bit 2 is set, the end device associates to a coordinator. This is done by sending out an active scan to detect beacons from nearby networks. The active scan selects one channel and transmits a Beacon Request command to the broadcast address and the broadcast PAN ID.
  • Page 46 Operation Networking If A2 bit 1 is set, the coordinator will issue an energy scan, similar to the active scan. It will listen on each channel specified in the SC parameter for the time indicated by the SD parameter. After the scan is complete, the channel with the least energy is selected to form the new network.
  • Page 47 Operation Networking enabled. On demand queries occur when the AI command is issued, which can occur in Command mode, in API mode, or as a remote command. Device Status Messages Not all device status messages are related with association, but for completeness all device status types reported by XBee/XBee-PRO S2C 802.15.4 RF Module are listed in the following table.

  • Page 48: Clear Channel Assessment (Cca)

    Operation Clear Channel Assessment (CCA) Sleep conditions Since instructions stop executing while the device is sleeping, it is important to avoid sleeping when the device has work to do. For example, the device will not sleep if any of the following are true: 1.

  • Page 49: Serial Interface

    Operation Serial interface 44 dBm level (for example -40 dBm) temporarily blocks a transmission attempt. But if the energy level is less than that (for example -50 dBm), the transmission is not blocked. The intent of this feature is to prevent simultaneous transmissions on the same channel.

  • Page 50: Uart Data Flow

    Operation Serial interface to the device such that the serial receive buffer would overflow, then it discards new data. If the UART is in use, you can avoid this by the host side honoring CTS flow control. Serial transmit buffer When the device receives RF data, it moves the data into the serial transmit buffer and sends it out the UART or SPI port.

  • Page 51: Flow Control

    Operation Serial interface Flow control The XBee/XBee-PRO S2C 802.15.4 RF Module maintains buffers to collect serial and RF data that it receives. The serial receive buffer collects incoming serial characters and holds them until the device can process them. The serial transmit buffer collects the data it receives via the RF link until it transmits that data out the serial port.

  • Page 52: Spi Operation

    Operation SPI operation Asynchronous Parameters Asynchronous communication over a UART is configured with a start bit, data bits, parity, stop bits, and baud rate. Out of these, only parity and baud rate are configurable on the device for 802.15.4. This means that the connecting micro-controller must match the the start bits (1), the data bits (8), and the stop bits (1) of the device for proper communication.

  • Page 53: Spi Parameters

    Operation SPI operation SPI_ATTN: The device asserts this pin low when it has data to send to the SPI master. When you configure this pin for SPI operations, it is an output (not tri-stated). This signal alerts the master that the slave has data queued to send.

  • Page 54: Slave Mode Characteristics

    Operation I/O support Slave mode characteristics In slave mode, the following apply: SPI Clock rates up to 5 MHz (5 Mb/s) are possible. Data is MSB first. It uses Frame Format Mode 0. This means CPOL= 0 (idle clock is low) and CPHA = 0 (data is sampled on the clock’s leading edge).

  • Page 55: Digital I/O Line Support

    Operation I/O support Digital I/O line support Digital I/O is available on pins D0 through D8. Each of these pins may be configured as 3, 4, or 5 with the following meanings: 3 is digital input 4 is digital output low 5 is digital output high Pins D0 through D8 are available for digital input, but only D0 through D7 are available for digital output.
  • Page 56 Operation I/O support In this example, note the following: 83 indicates RX Packet: 16-bit Address I/O frame (0x83). 00 00 indicates 16-bit source address. 00 indicates RSSI (does not apply). 00 indicates options. 01 indicates the number of samples. 03 3E mask to indicate which lines are sampled (A0, D8, D5, D4, D3, D2, and D1). 01 2A digital sample that indicates that D8 is high, D5 is high, D4 is low, D3 is high, D2 is low, and D1 is high.

  • Page 57: Periodic I/O Sampling

    Operation I/O support Multiple samples per packet The IT parameter specifies how many I/O samples can be transmitted in a single OTA packet. Any single-byte value (0 - 0xFF) is accepted for input. However, the value is adjusted downward based on how many I/O samples can fit into a maximum size packet;...

  • Page 58: Change Detect I/O Sampling

    Operation I/O support Although samples may be taken every millisecond, IR*IT should be at least 20 milliseconds. This allows time for OTA transmission and output on the serial port of the receiving module. Destination node On the destination node, the IU parameter enables the serial port to output I/O samples it receives. IU is set to 1 by default.

  • Page 59: Wakeup I/O Sampling

    Operation I/O support Wakeup I/O sampling Bit 2 of the SO parameter specifies whether or not the device automatically samples the ADC/DIO lines on wakeup. On the receiving side the I/O sample may go to the I/O pins, the serial port, both, or neither based on the settings of the IA (I/O Input Address) and IU (I/O Output Enable) parameters.

  • Page 60: Output Control

    Operation Sleep support I/O line passing details The same message is received for both I/O sampling and for I/O line passing. But I/O line passing only occurs if IA matches the short or long address of the sending node or if IA is 0xFFFF to match a sample from any node.

  • Page 63: Node Discovery

    Operation Node discovery Indirect transmissions can only occur on a Coordinator. Thus, if all nodes in a network are End Devices, only direct transmissions occurs. Indirect transmissions are useful to ensure packet delivery to a sleeping node. The Coordinator currently is able to retain up to five indirect messages. Direct transmission A Coordinator can be configured to use only direct transmission by setting the SP (Cyclic Sleep Period) parameter to 0.

  • Page 64: Node Discovery In Compatibility Mode

    Operation Node discovery When the node discovery command is issued in AT command mode, all other AT commands are inhibited until the node discovery command times out, as specified by the NT parameter. After the timeout, an extra CRLF is output to the terminal window, indicating that new AT commands can be entered.

    Migrate from XBee through-hole to surface-mount devices We design the XBee surface-mount and through-hole devices to be compatible with each other and offer the same basic feature set. The surface-mount form factor has more I/O pins. Because the XBee device was originally offered in only the through-hole form factor, we offer this section to help you migrate from the through-hole to the surface-mount form factor.

  • Page 172 PCB design and manufacturing The XBee/XBee-PRO S2C 802.15.4 RF Module is designed for surface-mount on the OEM PCB. It has castellated pads to allow for easy solder attach inspection. The pads are all located on the edge of the module, so there are no hidden solder joints on these modules. Recommended solder reflow cycle Recommended footprint and keepout Flux and cleaning...

    PCB design and manufacturing Recommended solder reflow cycle Recommended solder reflow cycle The following table provides the recommended solder reflow cycle. The table shows the temperature setting and the time to reach the temperature; it does not show the cooling cycle. Time (seconds) Temperature (degrees C) The maximum temperature should not exceed 260 °C.
  • Page 174 PCB design and manufacturing Recommended footprint and keepout While the underside of the module is mostly coated with solder resist, we recommend that the copper layer directly below the module be left open to avoid unintended contacts. Copper or vias must not interfere with the three exposed RF test points on the bottom of the module (see below).

  • Page 175: Flux And Cleaning

    PCB design and manufacturing Flux and cleaning Flux and cleaning We recommend that you use a “no clean” solder paste in assembling these devices. This eliminates the clean step and ensures that you do not leave unwanted residual flux under the device where it is difficult to remove.
  • Page 176 PCB design and manufacturing Rework following information is given as a guideline in such cases to increase the chances of success during rework, though the warranty is still voided. The module may be removed from the OEM PCB by the use of a hot air rework station, or hot plate. Care should be taken not to overheat the module.
