EZRADIO® Si4455 TWO-WAY AND Si4012/Si4355 ONE-WAY LINK DEVELOPMENT KIT USER’S GUIDE
1. OverviewThank you for your interest in Silicon Labs’ EZRadio® product family. The Silicon Labs EZRadio Si4455 Two-WayLink and Si4012/Si4355 EZRadio One-Way Link Development Kit (P/N EZR-LCDK2W-XXX and P/N 4012-LCDK1W-XXX) contains everything you need to familiarize yourself with and evaluate the Silicon Labs EZRadiofamily. The two-way kit has three versions: one for the 434 MHz band, one for the 868 MHz band, and one for the915 MHz band. The one-way kit has two versions: one for the 434 MHz band, and one for the 915 MHz band. Thekey features of the development kit are as follows:
The baseboards have an LCD display and four LEDs to display information and four push-buttons to receive user commands. Additionally, the Silicon Labs Toolstick Base Adapter is integrated on the board to be easily connected to the PC.
The RF pico board provides connection to the radio device (either Si4455 transceiver, Si4355 receiver, or Si4012 transmitter). All supported types of RF pico boards can be applied to the baseboard.
The provided software pack contains all the documentation and files needed to develop a user application.
The kit supports the use of the Silicon Laboratories Integrated Development Environment (IDE) for software debugging and the use of the Keil & SDCC C compiler, assembler, and linker toolchain.
The kit supports use of the Wireless Development Suite (WDS) for setting radio parameters and managing application firmware.
The baseboards come with the EZRadio range test demo application. The range test demo implements Packet Error Rate (PER) measurement. PER is generally used in wireless systems to measure the quality of the RF link in given circumstances.

2. Range Test Demo
2.1. Basics
As earlier described, the range test demo is used to provide measured results on the quality of the RF link.
The demo uses two RF nodes: the LCD baseboard + RF picoboard. One node is used as the ‘transmitter’ (TX) andthe other as the ‘receiver’ (RX). The Si4455 node can be either a transmitter or receiver. The Si4355 node can beonly a receiver and the Si4012 node can be only a transmitter.
The transmitter sends packets to the receiver repeatedly with half second intervals. The packet includes theaddress of the transmitter and number of the sent packet. The packet number increments from packet to packet.
The receiver receives the packet and checks its address. If their addresses match, the packet number is stored. Intwo-way development kits, the receiver can send back an acknowledge packet (ACK) to the transmitter. The ACKpacket also includes the address and packet number of the received packet.
PER can be calculated with the following equation:
where:PER: packet error rate (%).
PTX: number of sent packets.
PRX: number of received packets.
In two-way development kits the transmitter can calculate PER using the following data:PTX: packet counter to be included in the packet.
PRX: number of all the received acknowledge packets.
Receiver can calculate PER using the following data:PTX: packet number included in the last received packet.
PRX: number of all received data packets.
2.2. RF and Packet Parameters
This section provides information on user parameters of the range test demo. All the parameters (excluding fre-quency band and self node address) can be changed in the demo through its menu system (see section “2.4.Menu System of the Range Test Demo”). The following parameters are available:
RF parametersFrequency band (defined by the HW)Communication frequencyModulationData rateOutput power
Packet parametersPacket lengthMaximum number of sent/received packetsSelf node address (defined by the HW)Destination node address
Demo parameters are stored in the MCU’s flash memory and restored after power-on reset. Default values areloaded if no parameters were previously stored in the flash.It is also possible to define custom RF parameters for communication. Custom parameters can be stored with theWireless Development Suite (WDS). For more information on creating and storing custom RF parameters, refer tothe “WDS User’s Guide for EZRadio Next Generation”.

2.2.1. Frequency and Frequency Bands
The RF pico board has an on-board antenna and RF matching to provide solutions for supported frequency bands.A stand-alone antenna can also be used with the SMA connector.
Different RF matchings are required for each frequency band. The range test demo automatically reads frequencyband information out of the on-board EEPROM and selects the appropriate frequency range.
Si4x55 devices support the following three frequency bands:
Low band: 285–350 MHz
Middle band: 425–525 MHz
High band: 850–960 MHz
The EZRadio Development Kits are provided for the middle and the high bands; however, the range test demosupports all the three bands. The demo can be used with low band RF pico boards as well.
The range test demo provides four different selectable frequencies in all the supported bands. Table 2. lists theavailable frequencies.
2.2.2. Modulation
User can select from three types of modulation:2GFSK with high precision TX crystal (TX: 30 ppm, RX: 30 ppm)*
2FSK/2GFSK (TX: 150 ppm, RX: 30 ppm) *
OOK*Note: 2GFSK is supported by Si4x55 devices. 2FSK is supported by Si4012 devices.
2.2.3. Data Rate
The user can select from three different data rates. Table 3 lists the available data rates.

2.2.4. Output Power
The current version of the range test demo does not support changing the output power. The output power isdefined for +11 dB for all the frequency bands.
2.2.5. Packet Length
The user can define the length of the communication packets. The packet length contains 4 bytes of preamble, 2bytes of synch word, at least 7 bytes long payload, and 2 bytes of CRC. Increasing the packet length increases thelength of the used payload. The length of the whole packet can be selected from 15 bytes to 72 bytes.
2.2.6. Maximum Number of Sent/received Packets
The user can define the maximum number of sent and received packets. The demo stops after the defined numberof packets received or sent. The following packet counts can be selected: 200, 500, 1000, 2000, 5000, 10000.
2.2.7. Node Addresses
Each node of the range test demo reads the serial number of the connected RF pico board. The least significantbyte of its serial number (0 - 255) is used as node address. The user has to define the address of the destinationnode in the menu system to pair the appropriate nodes.
2.2.8. Custom Parameters
As described earlier, the user can store custom RF parameters into the devices with WDS. One custom field isavailable in each of the nodes. If custom parameter mode is selected, the RF parameters (frequency, modulation,data rate) are defined by the stored custom parameters and they cannot be changed.
Note: Since custom parameters belong to a defined frequency band, the firmware goes to error state if the frequency band ofthe custom parameters mismatches with the frequency band of the connected RF pico board.
2.3. Error statesIn case of critical error, the demo goes to error state. Power-on-reset can force the demo out of error state. In errorstate, LED4 is continuously ON and an error message is shown on the LCD screen.
Critical errors:
1. Error message: No RF pico board found! Connect an EZRadio RF pico then Reset!Cause: There is no supported RF pico connected to the LCD baseboard.Solution: Connect a supported EZRadio RF pico board (Si4x55 or Si4012) and reset the application.
2. Error message: Not supported radio! Connect a Si4x55 type RF pico then Reset!Cause: The connected RF pico board holds unsupported radio. Solution: Connect a supported EZRadio RF pico board (Si4x55 or Si4012) and reset the application.
3. Error message: Not supported custom frequency band! Custom freq band mismatches with RF pico.Cause: Frequency band of the connected RF pico board mismatches with frequency band of the stored
custom parameters.
Solution 1: Change custom parameters with WDS to match with the connected RF pico board.
Solution 2: Change the connected RF pico board to match with the stored custom parameters.
Solution 3: Use selected parameters instead of the custom parameters.

2.4. Menu System of the Range Test Demo
After running the demo, the first screen is the Welcome Screen. The Welcome Screen is shown for up to 1.5 sec-onds or for as long as any of the push buttons are pressed. The second screen provides information on the firm-ware, covered device name, firmware name, and version number of the firmware is displayed.
Figure 4. Welcome Screen
Figure 5. Firmware Information
The on-screen menu system is designed for easy configuration. The RF and packet parameters of thecommunication can be configured as described in the previous sections.
Four push buttons are used to navigate the menu system: soft labels on the LCD screen display the currentfunction of the related buttons. In general, push button 1 (PB1) is used to go to the previous menu page; pushbutton 2 (PB2) is used to select between menu items, push button 3 (PB3) is used to change value of the menuitem, and push button 4 (PB4) is used to access the next menu page. Some of the menu items have more than tenpossible values. In such cases, not only PB3 can be used to increase the value of the menu item, but PB2 and PB3can be used together to decrease its value. To decrease such values, push and hold PB2 and then push PB3several times to reach the required value.
A small arrow ( ) points to the actual menu item. The demo can be configured through six menu pages.
The first page is used to select the functionality of the demo. The range test can be performed in single way (TX—transmit or RX—receive mode)* or bidirectional (TRx—transceiver mode)** radio communication. If custom RFparameters are stored, the user can choose between “Custom” or “Select” RF parameters. If “Custom” RFparameters is selected, the user can only check but not change the RF parameters on the following menu pages.
Notes:1. Si4455 devices can be both transmitters or receivers; Si4355 devices can be only receivers, and Si4012 devices can be
only transmitters.2. Bidirectional mode is only supported by Si4455 devices.
Figure 6. Menu Page: System Function 1/6
EZRadio-DK Range Test Demo
Rev. 0.2 9
The frequency and the modulation can be selected on the second menu page. Selectable frequency values belongto the frequency band of the RF pico board. Modulation can be “2GFSK_I”, which refers to 2GFSK with high-preci-sion TX crystal, “2GFSK_h”, which refers to 2GFSK with low cost TX clock, and “OOK”.
Figure 7. Menu Page: RF Parameters 2/6
On the third menu page, only the data rate can be selected by the user. The second menu item only informs theuser about deviation or bandwidth RF parameter, which depends on the selected modulation and data rate.“Deviation” is shown if the selected modulation is 2GFSK and “Bandwidth” if the modulation is OOK.
Figure 8. Menu Page: RF Parameters 3/6 (Modulation is 2GFSK)
Figure 9. Menu Page: RF Parameters 3/6 (Modulation is OOK)
Figure 10. Menu Page: RF Parameters 4/6 (Output power is not shown in one-way receiver mode)
The fifth and sixth menu page is used to configure the packet configuration of the range test demo. PB2 + PB3button combo can be used on both pages to decrease the value of the selected menu item.
Packet length and maximum number of packets can be selected according to section “2.2.5. Packet Length” andsection “2.2.6. Maximum Number of Sent/received Packets”. Packet length cannot be set if RX mode operation isselected previously, since the received packet contains the length information.

The Self ID field is filled up automatically based on the serial number of the used RF pico board. It is important tosetup the destination ID accurately, otherwise the link will not work. The destination ID has to be the self ID of theother device.
Figure 13. Menu Page: Node Parameters 6/6
As described earlier, demo parameters are stored in the MCU's flash memory and restored after power-on-reset.Default values are loaded if no parameters were previously stored in the flash. The default packet configuration ofthe demo is the following:
Destination ID is the same as the Self ID
Packet length is 15 bytes
Max. packets is 1000 packets

2.5. Test Modes2.5.1. Bidirectional (TRx) Range Test
After the demo is fully configured, it proceeds to the demo screen, where the range test can be started. The screenis divided into three sections. At the top of the screen, soft labels show the functions of the LEDs. LED1 blinkswhen a packet is transmitted; LED2 blinks if a packet is successfully received (with valid CRC and packet contentthat matches the expected value).The bar graph under LED3 shows the actual Receive Signal Strength Level(RSSI) of the received packet (shown and refreshed after a packet is received).
The middle section of the screen shows the part number of the radio and the source / destination addresses witharrows showing direction of the communication. RF parameters can be checked in the middle section beforetransmission / reception is started.
Figure 14. Demo Screen (TRx Mode)
On the bottom of the screen, the soft labels show the actual functionality of the push buttons. PB3 are used toreturn to the configuration menu. After entering demo mode, both ends of the link are in receive mode. The teststarts if any of the link nodes starts to transmit ping packets. Transmission can be initiated by pressing PB1. Afterthat, the originator transmits a ping packet for the other node. If it receives the packet correctly, it transmits back anacknowledgment packet. Each ping packet has a serial number (increased by the originator after every packettransmission), which is transmitted back by the acknowledgment packet. If the originator receives theacknowledgment within a predefined timeout, then it considers the link working, otherwise it increases the numberof missed packets by one. The originator also stores the number of transmitted PING packets so the demo cancalculate the Packet Error Rate based on this information. The Packet Error Rate is updated on the third line of theLCD after each packet transmission according to PER equation in section “2.1. Basics”.
Figure 15. Running PER Test (TRx Mode)
The demo runs as long as the number of transmitted packets reaches the predefined number or until it isinterrupted by PB1.
The user can check predefined RF parameters of the measurement any time during a running test by using PB4.PB4 also is used in the info screen to show the actual results of the running measurement. Info screen is alsoavailable after all the packets are transmitted and the test is finished.

2.5.2. Single Way (Tx-Rx) Range Test
The range test also can be performed with single way radio communication. In this case, one end of the link needsto be setup as a transmitter (this will be the originator as described in the bidirectional link) and the other end of thelink needs to be a receiver. The test needs to be started at the transmit side by pressing PB1. The demo runs aslong as the number of transmitted or received packets reaches the predefined number or until the demo isinterrupted by PB1. The user can follow the number of transmitted packets on the LCD screen.
Figure 16. Running PER Test (Tx Mode)
The single way range test demo works the same as the bidirectional range test; however, the number of lostpackets and the packet error rate is defined only at the receive side and is based on the first and last receivedpacket ID.
Figure 17. Running PER Test (Rx Mode)
2.6. How to Carry the Range Test OutConnect RF pico boards to the two LCD baseboards. Put batteries into the devices and switch the devices on.Select both devices to be in TRX mode or one of them to be RX and the other to be in TX mode (note that Si4355base devices can only be receivers and Si4012 devices can only be transmitters). Select the required demoparameters or start the measurements with the automatically reloaded configuration.
Check if transmitter sends packets and receiver answers as well.
The range test can be performed inside a building if indoor propagation is tested. However, it is advised to performthe test outside the building, line-of-sight to get the best possible range result. If PER>1%, reset the PER on thetransmitter and try to walk further in the area. Propagation conditions usually improve if the user is furtherdistanced from a possibly shadowed area.
