The swivel antennas provided with the REB233CBB Module are tested and approved (see A.3). One antenna must be mounted on each SMA coaxial connector ‘X2’ and ‘X3’ port of the Radio PCB. Note, to ensure compliance, the use of any other antenna type is not permitted, see A.3. Atmel AT03911: REB233CBB Module – User Manual [APPLICATION NOTE] 42156A−WIRELESS−07/2013 3 5. Functional description The block diagram of the REB233CBB Module is shown in Figure 5-1. The Radio PCB and Microcontroller PCB are connected via a mounting header. The Radio PCB is not functional without connecting it correctly to the Microcontroller PCB. The Radio PCB is equipped with two approved antennas; see A.3 and [2], to enable antenna diversity (AD) operation.The Microcontroller PCB controls the Radio PCB, provides the power supply as well as the user interface. The user interface consists of three LEDs and two pushbuttons for manual user control of the module. Additional microcontroller (MCU) GPIOs, like USART, UART and JTAG, are available to control the module with a host-PC. Figure 5-1.

The radio transceiver is a high performance RF-CMOS 2.4GHz radio transceiver targeted for IEEE802.15.4, ZigBee, RF4CE, 6LoWPAN, and ISM applications. The identification EEPROM carries Radio PCB information used by the Microcontroller PCB. 5.3 Antennas The antennas intended for the REB233CBB Module, see A.3 and [2], are to be connected to the SMA connectors on the Radio PCB. A proper antenna orientation can enhance the radio link budget. Especially an orthogonal orientation between the two antennas, see Figure 6-1, decreases the probability of RF signal extinction. 5.4 Microcontroller PCB The Microcontroller PCB carries the ATxmega256A3 MCU [4]. The MCU is a high-performance, low-power 8/16-bit Atmel AVR® XMEGA® MCU with 256KB in-system, self-programmable flash, 8KB boot code section with independent lock bits, 16KB internal SRAM and 4KB EEPROM. 5.5 Power Supply The REB233CBB Module is powered by two AAA batteries. The power switch disconnects batteries from the entire board. External power is not routed through the power switch. Note: There is no protection against over-voltage. 5.6 LEDs and buttons For simple applications, and to provide status information, a user interface is provided on-board, consisting of three LEDs and two pushbuttons The LEDs (D1…D3) are connected to PB0..2 for active-high operation, whereas the pushbutton (T1) pulls PB3 to GND. The second pushbutton (RESET) is connected to the MCUs reset pin. Table 5-1. 5.7 LED/Button connection ATxmega256A3 I/O ATxmega256A3 I/O PB0 (6) D1 PB3 (9) T1 PB1 (7) D2 RESET T2 PB2 (8) D3 UART/USART The signal lines for asynchronous serial operation of the Atmel ATxmega256A3 (USARTD0) are connected to header USARTD0. In addition, the MCU reset line is connected to pin 5 of this header. This can be used to work with a serial boot loader. No level conversion is done; therefore, an external RS232/TTL conversion circuit is required. The header pin-out mates with the available RS232/TTL converter in Figure 5-3. Table 5-2.

PC connectivity can be easily achieved by using a serial to USB level shifter stick [8] as shown in Figure 5-3. Figure 5-3. USB level shifter stick. 5.8 ID EEPROM The REB233CBB Module identifies the Radio PCB by checking the correct content of the Radio PCB identification (ID) EEPROM, which handles information about the Radio PCB, the node MAC address and production calibration values. This ensures no other Radio PCB type can be used in conjunction with the delivered Microcontroller PCB and firmware. The firmware running on the Microcontroller PCB checks the correct content of the Radio PCB ID-EEPROM before continuing with any radio operation. In case of wrong or unexpected content of the Radio PCB ID-EEPROM the operation is stopped which is indicated by LEDs D1…D2 blinking. Table 5-3 shows a detailed description of the Radio PCB ID-EEPROM data structure. Table 5-3. ID EEPROM mapping.

Firmware description 7.1 Range measurement The REB233CBB Module is pre-flashed with the RF performance test suite featuring a range measurement application. Each module operates in a standalone manner, and is able to transmit or receive data frames. A successful transmit or receive operation is indicated by a blinking LED. 7.1.1 Power up the modules Apply power to both modules by switching on the power switch. In consequence of, a module runs a power-on check and indicates the successful completion by switching on the second of the three LEDs. 7.1.2 Run range measurement application Select one of the REB233CBB Module and press pushbutton T1 to start the range measurement application. First, the module initiates a connection and configuration procedure by sending broadcast frames and waiting for a response from the second module. After successful configuration, the module turns on LED-D1 indicating this status. The initiator starts transmitting data frames. Each data frame transmission is indicated by blinking the TX status LEDD2. A successful data frame reception on the second node is indicated by blinking the RX status LED-D3. The frame transmit repetition rate is fixed to ensure FCC compliance; the repetition rate cannot be changed. The RX status LED stops blinking if no data frames are received, such as when, for example, the node has left the communication range. Data frame transmission can be stopped by pressing T1 once more on the node transmitting frames. The REB233CBB Modules are able to transmit and receive simultaneously. Pressing pushbutton T1 on both nodes initiates each node to transmit frames. Operating modes are indicated as: LED-D1 a successful start-up, LED-D2 in transmit and LED-D3 in receive mode. Note: The node configuration gets lost when resetting or switching off the radio modules power supply; to restart, a reset or power cycle is required for both REB233CBB Modules before pressing T1 on one (or both) REB233CBB Module(s). 7.2 Packet error rate measurement The RF performance test suite features a packet error rate measurement (as defined by IEEE802.15.4), and allows to explore various radio transceiver features, radio transceiver registers, and performance by tuning with customized configurations. For this application, at least one REB233CBB Module needs to be connected to a PC. 7.2.1 Module preparation 1. Prepare REB233CBB Modules as described in Chapter 4.2. 2. Make sure that the power switch on both modules is in the off position. 3. Plug an USB level-shifter into a free USB port on your host-PC. Interconnect this adapter and one of the REB233CBB Modules via the 6-pin ribbon cable so that it fits the notch on the adapter and the colored stripe of the ribbon cable connects to pin 1 of the header USARTD0.
