1. XBee®/XBee‐PRO® RF Modules The XBee and XBee-PRO RF Modules were engineered to meet IEEE 802.15.4 standards and support the unique needs of low-cost, low-power wireless sensor networks. The modules require minimal power and provide reliable delivery of data between devices. The modules operate within the ISM 2.4 GHz frequency band and are pin-for-pin compatible with each other. Key Features Long Range Data Integrity XBee Low Power XBee • Indoor/Urban: up to 100’ (30 m) • TX Peak Current: 45 mA (@3.

XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] The XBee and XBee‐PRO RF Modules are pin‐for‐pin compatible. Mounting Considerations The XBee®/XBee-PRO® RF Module was designed to mount into a receptacle (socket) and therefore does not require any soldering when mounting it to a board. The XBee Development Kits contain RS-232 and USB interface boards which use two 20-pin receptacles to receive modules. Figure 1‐02. XBee Module Mounting to an RS‐232 Interface Board.

Total unadjusted error is the difference between the transition voltage to the current code and the ideal straight‐line trans‐ fer function. This measure of error includes inherent quantization error (1/2LSB) and circuit error (differential, integral, zero‐ scale, and full‐scale) error.

2. RF Module Operation Serial Communications The XBee®/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). UART Data Flow Devices that have a UART interface can connect directly to the pins of the RF module as shown in the figure below.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Transparent Operation By default, XBee®/XBee-PRO® RF Modules operate in Transparent Mode. When operating in this mode, the modules act as a serial line replacement - all UART data received through the DI pin is queued up for RF transmission. When RF data is received, the data is sent out the DO pin. Serial-to-RF Packetization Data is buffered in the DI buffer until one of the following causes the data to be packetized and transmitted: 1.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Flow Control Figure 2‐03. Internal Data Flow Diagram DI (Data In) Buffer When serial data enters the RF module through the DI pin (pin 3), the data is stored in the DI Buffer until it can be processed. Hardware Flow Control (CTS). When the DI buffer is 17 bytes away from being full; by default, the module de-asserts CTS (high) to signal to the host device to stop sending data [refer to D7 (DIO7 Configuration) parameter].
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] ADC and Digital I/O Line Support The XBee®/XBee-PRO® RF Modules support ADC (Analog-to-digital conversion) and digital I/O line passing. The following pins support multiple functions: Table 2‐01. Pin functions and their associated pin numbers and commands AD = Analog‐to‐Digital Converter, DIO = Digital Input/Output Pin functions not applicable to this section are denoted within (parenthesis).
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] API Support I/O data is sent out the UART using an API frame. All other data can be sent and received using Transparent Operation [refer to p11] or API framing if API mode is enabled (AP > 0).
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] I/O Line Passing Virtual wires can be set up between XBee®/XBee-PRO® Modules. When an RF data packet is received that contains I/O data, the receiving module can be setup to update any enabled outputs (PWM and DIO) based on the data it receives. Note that I/O lines are mapped in pairs. For example: AD0 can only update PWM0 and DI5 can only update DO5.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] XBee®/XBee-PRO® Networks The following terms will be used to explicate the network operations: Table 2‐02. Terms and definitions Term Definition PAN Personal Area Network - A data communication network that includes one or more End Devices and optionally a Coordinator.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Association Association is the establishment of membership between End Devices and a Coordinator. The establishment of membership is useful in scenarios that require a central unit (Coordinator) to relay messages to or gather data from several remote units (End Devices), assign channels or assign PAN IDs. An RF data network that consists of one Coordinator and one or more End Devices forms a PAN (Personal Area Network).
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] 2. Check A2 parameter - Reassign_Channel Flag (bit 1) Set (bit 1 = 1) - The Coordinator issues an Energy Scan. The Energy Scan selects one channel and scans for energy on that channel. The duration of the scan is specified by the SD (Scan Duration) parameter. Once the scan is completed on a channel, the Energy Scan selects the next channel and begins a new scan on that channel. This process continues until all channels have been scanned.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] The End Device selects a Coordinator to associate with according to the A1 parameter “Reassign_PANID” and “Reassign_Channel” flags: Reassign_PANID Bit Set (bit 0 = 1)- End Device can associate with a PAN with any ID value. Reassign_PANID Bit Not Set (bit 0 = 0) - End Device will only associate with a PAN whose ID setting matches the ID setting of the End Device.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] XBee®/XBee-PRO® Addressing Every RF data packet sent over-the-air contains a Source Address and Destination Address field in its header. The 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.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Modes of Operation XBee®/XBee-PRO® RF Modules operate in five modes. Figure 2‐07. Modes of Operation Idle Mode When not receiving or transmitting data, the RF module is in Idle Mode.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Direct Transmission A Coordinator can be configured to use only Direct Transmission by setting the SP (Cyclic Sleep Period) parameter to "0". Also, a Coordinator using indirect transmissions will revert to direct transmission if it knows the destination module is awake. To enable this behavior, the ST (Time before Sleep) value of the Coordinator must be set to match the ST value of the End Device.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Sleep Mode Sleep Modes enable the RF module to enter states of low-power consumption when not in use.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] low. When waking the module, the pin must be de-asserted at least two 'byte times' after CTS goes low. This assures that there is time for the data to enter the DI buffer. Cyclic Sleep Modes Cyclic Sleep Remote (SM = 4) • Typical Power-down Current: < 50 µA (when asleep) • Wake-up time: 2 msec The Cyclic Sleep Modes allow modules to periodically check for RF data.
XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23] Command Mode To modify or read RF Module parameters, the module must first enter into Command Mode - a state in which incoming characters are interpreted as commands. Two Command Mode options are supported: AT Command Mode [refer to section below] and API Command Mode [p57]. AT Command Mode To Enter AT Command Mode: Send the 3-character command sequence “+++” and observe guard times before and after the command characters.
3. RF Module Configuration Programming the RF Module Refer to the Command Mode section [p25] for more information about entering Command Mode, sending AT commands and exiting Command Mode. For information regarding module programming using API Mode, refer to the API Operation sections [p57]. Programming Examples Setup The programming examples in this section require the installation of Digi's X-CTU Software and a serial connection to a PC.

This API frame can be used to send commands to a remote module to read or set command parameters.
