The RAILtest application (RAILtest) provides you with a simple tool
for testing the radio and the functionality of the RAIL library. For
more advanced usage, developers must write software against the
RAIL library and create a custom radio configuration.
Proprietary is supported on all EFR32FG devices. For others, check the device's data
sheet under Ordering Information > Protocol Stack to see if Proprietary is supported. In
Proprietary SDK version 2.7.n, Connect is not supported on EFR32xG22.

Overview
1 Overview
The following is a summary of functionality provided as part of the RAILtest application:
• Transmit and receive packets
• Schedule transmits at a specific time in the RAIL timebase
• Configure RAIL address filtering to receive only specific packets
• Enable CCA mechanisms (CSMA/LBT) to validate that a channel is clear before transmit
• Set a timer callback in the RAIL timebase to see how the RAIL timer API works
• Change the transmit channel within the current configuration's band
• Change the transmit power level
• Enable RF energy sensing of a specified duration across the 2.4 GHz and/or Sub 1-GHz bands, and sleep to wake on this event.
• Output a continuous unmodulated tone for debugging
• Output a continuous modulated PN9 stream for debugging
• Enter into direct mode where data can be sent and received using asynchronous GPIOs as input and output
1.1 About RAILtest Versions
Gecko SDK Suite (GSDK) v3.0 contains an update to RAILtest, released as version 2.9. Users who have not yet transitioned to GSDK
v3.0 and are still working with GSDK v2.7.x will be using RAILtest version 2.8. During transition, information is supplied for both versions.
1.2 Modes
RAILtest can be in a number of different modes. Each of these modes enables a subset of the test application's functionality, so that
nonsensical commands (such as trying to transmit a tone and a packet at the same time) are ignored. The following lists supported
modes, with a short description.
•None - The app is doing nothing, but the radio may be on. Parameters can be set in this mode based on the current radio state, and
the timer can be used.
• Stream - Send a stream of pseudo-random bits.
• Tone - Send a tone at the carrier frequency.
• ContinuousTx - Send an unending stream of packets, separated by a configurable delay.
• DirectMode - Send data to and from a GPIO, without any packet handling.
• PacketTx - Send a specific number of packets, with a summary print at the end.
• ScheduledTx - Send one packet scheduled in the future.
• TxAfterRx - Schedule a packet after each RX after a specific delay.
• RxOverflow - Overflow on receive by delaying in RAILCb_RxPacketReceived.
• TxUnderflow - Underflow by not loading data for the next TX sequence.
• TxCancel - Cancel a single packet transmit to force an error callback.
• RfSense - Sense RF energy to wake the radio.
• PER (Packet Error Rate) test - A GPIO is toggled, and stats are gathered on received packets.
• BER (Bit Error Rate) test - Statistics are gathered on received bits.

Command Line Interface
2 Command Line Interface
The most powerful way to interact with the sample application is through the provided command line interface.
2.1 Command Input
The syntax for this interface is the standard command [arg0, arg1, ...] syntax, where the number and type of arguments depend on the
specific command. Numeric values can be prefixed with 0x to indicate hexadecimal values.
In RAILtest 2.8 (GSDK v2.7.x), the maximum number of arguments to any command is set by the value of MAX_COMMAND_ARGUMENTS,
and the maximum length of each command line is set by the value of APP_COMMAND_INTERFACE_BUFFER_SIZE.
In RAILtest 2.9 (GSDK v3.0), the maximum number of arguments to any command is set by the value of
SL_CLI_MAX_INPUT_ARGUMENTS, and the maximum length of each command line is set by the value of
SL_CLI_INPUT_BUFFER_SIZE.
For a full listing of the command options see section 5.3.4 Full Help Textor use the help command.
2.2 Command Responses
All responses to commands are formatted in a human readable yet parsable format. This format has two variations: single and multiline.
Both follow these rules.
• Start and end with curly braces { }
• List the command name, enclosed in parentheses ( )
• Contain any number of tag/value pairs enclosed in curly braces { }
• Carriage returns and line feeds are treated as whitespace by any parser
2.2.1 Single Response
Used when a command has a single response.
• There is a single start/end curly brace wrapper
• Tag/value pairs are wrapped in a single set of curly braces, separated by a colon {tag:value}.
Example:
> getchannel
{{(getchannel)}{channel:4}}
2.2.2 Multi Response
Used when a command may have multiple responses, such as when reading a block of memory or receiving multiple packets.
• Response starts with a header, delimited by a hash # at the start of the line.
• Header includes the command name, followed by any tags individually wrapped with curly braces { }.
• Following the header, any number of responses can be provided.
• Data lines do not contain the command name or tags, only the values that correspond to the tags in the order described in the header.

Peripherals
3 Peripherals
3.1 Buttons
When enabled, RAILtest can use up to two buttons. When pressed for a short duration (less than 1 second), the first button causes
RAILtest to transmit one packet. When pressed for a long duration (greater than 1 second), the first button causes RAILtest to continuously
transmit packets until the button is pushed again for a long duration. Pressing the second button causes RAILtest to increment the channel
number used for TX and RX until the channel number wraps around to its beginning value.
Starting in RAILtest 2.9 (GSDK v3.0), button functionality is disabled by default. In order to enable button functionality, the Simple Button Driver software component needs to be enabled with an instance name of btn0 for the first button and btn1 for the second
button.
3.2 LEDs
When enabled, RAILtest can use up to two LEDs. The first LED toggles when a packet is successfully received, and the second LED
toggles when a packet is successfully transmitted.
Starting in RAILtest 2.9 (GSDK v3.0), LED functionality is disabled by default. In order to enable LED functionality, the Simple LED Driver software component needs to be enabled with an instance name of led0 for the first LED and led1 for the second LED.
3.3 LCD
When enabled, RAILtest can use the LCD to show packets received and transmitted as well as the channel selected and radio activity.
Starting in RAILtest 2.9 (GSDK v3.0), LCD functionality is disabled by default. In order to enable LCD functionality, the RAILtest Ap-plication, Graphics software component needs to be enabled.

Application Features
4 Application Features
4.1 Packet Mode
The application starts in packet mode with the receiver enabled. In this mode the application receives and transmits packets using the
radio's frame controller hardware. To disable receive use the rx 0 command. To transmit use tx [numPackets] or press button PB0
if button support is enabled. To toggle the continuous transmit mode, hold PB0 for a couple of seconds if button support is enabled, or
run the tx 0 command. When transmitting multiple packets or infinite packets there is a configurable delay in between each transmit. By
default this is 250 ms, but it can be set with the setTxDelay command.
All received packets are printed to the console with information like CRC, RSSI, and timestamp as long as notifications are enabled.
Notifications are enabled by default, but they can be turned off with the setRxNotification 0 command.
The application by default sends a fixed packet, but it is possible to override the values through setTxPayload. The command allows
you to modify the values of the payload at specific offsets. For instance, to modify the first 4 bytes sent in the packet to be 0x01 0x02
0x03 0x04, use:
setTxPayload 0 0x01 0x02 0x03 0x04
To view the currently configured TX Packet information, use printTxPacket.
Note: The packet format depends on the current PHY configuration. If your PHY has a dynamic frame length byte then that will be
used to determine how much data should be sent.
4.2 Direct Mode
In direct mode the radio will still attempt to decode received packets, but it will only be able to transmit packets sent over the DIN pin. The
GPIOs for direct mode are fixed for now to the following pins.
DOUT - EFR32_PC11 -> EXP_HEADER16/WSTK_P13
DIN - EFR32_PC10 -> EXP_HEADER15/WSTK_P12
The data on these pins is asynchronous and can be connected directly to a UART. To enter direct mode, issue the directMode 1
command after starting the app. To leave direct mode use directMode 0. If you want to transmit, you must enable the transmitter by
issuing directTx 1 and later stop it with directTx 0. Receive is controlled using the standard rx 1/0 command, but is enabled by
default when not transmitting.
Note:Direct mode does not work in certain modulations (for example 4FSK). If you require this mode contact support to verify your
configuration.
4.3 Channels/Frequencies
The specific channel configuration depends on the PHY configuration you have chosen for your test app. To switch between channels
use the setChannel [num] command. If RX is active (rx 1) then any TX or RX in progress will be aborted and the new channel
switched to. In addition, if button support is enabled, you can use button PB1 to cycle through channels.
To modify your frequency to a value not defined in the channel list, you will need to set the application into the FREQUENCY_OVERRIDE
debug mode via setDebugMode which tells the application to ignore the current channel selection. Once in the FREQUENCY_OVERRIDE
debug mode, you can use the freqOverride command to switch to another center frequency.
Note: The freqOverride command requires you to be in FREQUENCY_OVERRIDE debug mode. The radio state must also be IDLE
for the frequency to be modified -- call rx 0 first.
setDebugMode 1
freqOverride 865000000
To leave FREQUENCY_OVERRIDE debug mode and return to normal channel-based operation, use setDebugMode 0.

Application Features
Caution: The modem is configured to a specific band. The application will not restrict you from changing the frequency out of band but
this could cause significant issues, including forcing a chip reboot.
4.4 Command Scripting
The command scripting feature built into RAILtest allows for CLI commands to be executed without back-and-forth interaction on the
command line. The same commands that can be executed one by one can be queued up within RAILtest and executed sequentially later.
Additionally, a command script can be saved to flash, and any script saved to flash will run automatically on device boot.
In RAILtest 2.8 (GSDK v2.7.x) support is integrated into RAILtest to use a command script in RAM, but to use a command script in flash,
the Flash Data plugin must be enabled.
In RAILtest 2.9 (GSDK v3.0), to use a command script in RAM, the CLI Storage in RAM software component needs to be enabled
with an instance name of inst0. To use a command script in flash, the CLI Storage in NVM3 software component needs to be
enabled with an instance name of inst0.
This is an example of how to enter, print, and run a script from RAM. Note that the wait command needs to be used in order to allow
time for the first scripted command (that is, tx 1) to successfully run to completion before the second scripted command (that is, tx 2)
starts.
Note: For rapid command entry (for example, automated testing), you may need to increase the USART RX buffer from its default
value, specified by a define similar to SL_IOSTREAM_USART_VCOM_RX_BUFFER_SIZE in RAILtest 2.9, to account for long
command string entry being interrupted by chip interrupts. For lengthy (for example hours long) automated test programs, a
notable decrease in test time will come from disabling CLI command history, setting SL_CLI_NUM_HISTORY_BYTES to 0 (RAILtest 2.9).
4.5 RAIL Timebase
The microsecond RAIL timebase is used for features requiring specific timing. You can read this timebase with getTime, and you can
also set this microsecond timebase with setTime. Avoid changing the timebase when the timebase is actively being used, such as during
clear channel assessment, during scheduled TX or RX, and so on.

UG409: RAILtest User's Guide
Application Features
4.6 Scheduled TX
The RAIL API has its own timebase that can be used to schedule the start of transmits. It measures time as a 32-bit integer in microseconds. As part of this change many APIs will now return the time they were run, all RX packets report the time they were received, and all
TX packets return the time that the transmit was completed. There is also the command getTime to print the current time in the RAIL
timebase.
To test scheduled transmit we provide two commands: txAt and txAfterRx. These allow you to send a packet at an absolute time in
the RAIL timebase or exactly some number of microseconds after each receive, respectively.
Note: These APIs should provide reliable timing but you may have to adjust for overhead that relates to preamble and PA ramp time
in order to transmit at the exact time you want.
4.7 Clear Channel Assessment
The RAIL API provides the ability to specify a Pre-Transmit Operation for every transmit, one of which is Scheduled Transmit discussed
above. Others are also provided to support two common medium access methodologies that delay transmission until the channel is clear:
• CSMA-CA (Carrier Sense Multiple Access with Collision Avoidance) -- based on IEEE 802.15.4 specification
• LBT (Listen Before Talk) -- based on ETSI EN 300 220-1 specification
Both CSMA-CA and LBT are similar: Before transmission, a device waits for a random 'backoff' period of time and then performs a CCA
(Clear Channel Assessment) for a fixed period of time. If the channel is free, the transmit proceeds; if busy, the process is repeated with
a new random backoff period. The random backoff period is determined by a randomly chosen multiple of a fixed backoff unit of time.
For CSMA-CA, the random multiplier is a power-of-2 exponential whose range increases on each try up to a limit, and the CCA period is
typically short -- smaller than a backoff unit and around the time it takes a small packet to be transmitted. For LBT, the random multiplier
is linear and typically chosen to allow the random period to range up to the CCA period, which can be quite long -- much longer than the
on-air time of the actual transmission it's gating. LBT also specifies that if the channel is found busy during CCA, the process cannot
repeat until the channel is free.
In RAIL and RAILtest, several parameters are exposed through the setLbtParams and getLbtParams commands to configure either
CSMA-CA or LBT operation. Their interpretation depends on which mode has been chosen:
•minBo -- Minimum backoff. For CSMA-CA the first try's power-of-2 random exponential range, that is the backoff multiplier, will
range from 0 to 2^minBo - 1. Subsequent tries increase minBo by 1 up to maxBo. For LBT this is the minimum backoff multiplier
for all tries, typically 0.
•maxBo -- Maximum backoff. For CSMA-CA this is the maximum power-of-2 random exponential range to which subsequent tries
can increase. For LBT this is the maximum backoff multiplier for all tries, typically maxBo * backoff = duration. If both minBo
and maxBo are 0, a non-random fixed backoff time is configured.
•tries -- The maximum number of tries ('busy' CCAs), up to 15, that the CSMA-CA or LBT operation will tolerate before declaring
the transmission a failure due to channel busy. A value of 0 will perform no CCA assessments, and always transmit immediately.
• thresh -- The CCA RSSI threshold, in dBm, above which the channel is considered 'busy'.
• backoff -- The backoff unit period, in RAIL's microsecond time base. This is multiplied by the random backoff multiplier con-
trolled by minBo and maxBo to determine the overall backoff period. For random backoffs, this value must be in the range 100
to 511 microseconds; for fixed backoffs it can go up to 65535 microseconds.
•duration -- The CCA duration, in RAIL's microsecond time base. The radio determines the maximum RSSI during this period
for comparison against the CCA threshold.
•timeout -- An overall timeout, in RAIL's microsecond time base, for the operation. If transmission does not start before this
timeout expires, the transmission will fail. This is more important for limiting LBT due to LBT's unbounded requirement that if the
channel is busy, the next try must wait for the channel to clear. A value of 0 indicates that no timeout is imposed.
Several examples:
•RAILtest's default parameters are suitable for the IEEE 802.15.4 PHY for CSMA-CA, equivalent to: setLbtParams 3 5 4 -
75 320 128 0. This specifies up to 4 CCA attempts. The 1st will choose a random multiplier of 0..7 (2^3-1), the 2nd 0..15
(2^4-1), the 3rd 0..31 (2^5-1), and the 4th 0..31 since the maxBo limit is 5.

•ETSI EN 300 220-1 LBT's parameters in the 863 MHz band would be: setLbtParams 0 10 15 -80 500 5000 1000000.
This specifies a 5 millisecond CCA duration with random backoff period of 0..5 milliseconds (0..10 * 0.5 milliseconds) and a 1
second timeout limit in case the channel remains busy.
•A single CCA of 160 microseconds after a fixed 1024 microsecond backoff, against a -70 dBm threshold would be: setLbt-
Params 0 0 1 -70 1024 160 0.
In RAILtest, CSMA-CA and LBT are enabled as a mode applied to subsequent transmits through setLbtMode, whose choices are 'off',
'csma', and 'lbt'.
Note: On EFR32, LBT is currently implemented using the EFR32's CSMA-based hardware engine, so LBT parameters are mapped to
roughly equivalent CSMA parameters.
Note:Scheduled Transmit and Clear Channel Assessment are currently mutually exclusive, with Scheduled Transmit taking prece-
dence.
4.8 Address Filtering
The address filtering code examines the packet as follows.
Data0 Field0 Data1 Field1 Data2
In the above structure, anything listed as DataN is an optional section of bytes that will not be processed for address filtering. The FieldN
segments reference the specific sections in the packet that will be examined during filtering for addresses. There may be up to four
addresses per field and they may each have a size of up to 8 bytes. To set up address filtering, first configure where the addresses are
in the packet and how long they are. Next, configure what combinations of matches in Field0 and Field1 should constitute an address
match. Lastly, enter addresses into the tables for each field and enable them.
The configAddressFilter command can be used to set the offsets and sizes for the address fields as well as how combinations of
matches in Field0 and Field1 are combined to determine whether or not an address matches.
Configuring which combinations of Field0 and Field1 constitute a match is the most complex portion of the address filter. The easiest way
to think about this is with a truth table. If you consider each of the four possible address entries in a field, you can have a match on any
one of those or a match for none of them. This is shown in the 5x5 truth table below where Field0 matches are the rows and Field1
matches are the columns.
Fields No Match Address 0 Address 1 Address 2 Address 3
bit5 bit6 bit7 bit8 bit9
bit10 bit11 bit12 bit13 bit14
bit15 bit16 bit17 bit18 bit19
bit20 bit21 bit22 bit23 bit24
Since this is only 25 bits it can be represented in one 32bit integer, where a 1 indicates filter pass and a 0 indicates filter fail. This is the
matchTable parameter in the configAddressFilter command. For a simple one field configuration set the matchTable to 0x1fffffe
and for a two field configuration pairing indices across the fields use 0x1041040.
After you have configured address filtering you must also set which addresses are valid and enable them. This can be done with the
setAddress and setAddressEnable commands. You must also turn on the address filtering feature with the setAddressFilter-
ing command.
As an example, to configure an address of 0x00 0x01 0x02 0x03 in field0, index0 for a filter that has one field starting at offset 0 with
a length of 4 bytes, use the following commands.
silabs.com | Building a more connected world. Rev. 3.5 | 8
UG409: RAILtest User's Guide
Application Features
In addition to the standard address filtering, if the frame length decoding algorithm is by frame type, then additional filtering functionality
is available. Address filtering can be enabled or disabled based on the frame type that is decoded. This can be set by the addressFil-terByFrame command. This command takes an 8-bit bitmask, in which each bit represents whether addresses are present in that frame.
The least significant bit determines whether to apply the address filter to frame 0, and the most significant bit determines whether to apply
the address filter to frame 7. addressFilterByFrame must be called after configAddressFilter for it to take effect.
4.9 Automatic State Transitions
RAIL provides an API to configure state transitions to happen automatically on certain radio events:
• a successful receive
• a failed receive
• a successful transmission
• a failed transmission
All of these events can transition to a radio state of idle or receive. In addition, a transmission can be configured to happen after a
successful receive.
These states are configured through the setTxTransitions and setRxTransitions commands. Each of these commands take in
two radio states, which are passed in as single letter strings. To transition to receive after a transmission, regardless of its success, the
command is setTxTransitions r r.
When settings the receive transitions, there is also a third argument, a bitfield to configure which events count as errors. The documentation for this bitfield can be found in the RAIL library documentation. Calling setRxTransitions i i 0xFF will ignore all errors that
are possible to ignore, and transition the radio to idle after attempting to receive one packet.
In addition to the state transitions, timings can be set for the transitions. The six timings that are currently configurable are:
• idleToRx
• idleToTx
• rxToTx
• txToRx
• rxSearchTimeout
• txToRxSearchTimeout
Each of these timings configures an amount of delay between two states. The search timeouts allow you to set a maximum time that the
chip will sit in the RX search state. These can be used to implement short receive timeouts. The rxSearchTimeout is used when transitioning to receive from idle and the txToRxSearchTimeout is used when transitioning to receive from a past transmit. Setting
[rx|txToRx]SearchTimeout to zero disables the timeout and radio will stay in RX until an event changes the state. Transitions to idle simply
happen as fast as possible. Each timing is configurable in microseconds, up to a maximum of 13 ms, with the exception of txToRxSearchTimeout which could be up to a quarter of the RAIL timebase, which is 2^32/4 microseconds or 18 minutes. For example, to disable the
timeouts and set all other transitions to take 200 µs, use:
setStateTimings 200 200 200 200 0 0
4.10 Auto-Acknowledgment
RAIL contains auto-acknowledgment (ACK) APIs that are exposed through the RAILtest command interface. To initialize and enable this
functionality use autoAckConfig. For example, autoAckConfig rx 100 192 1000 will configure the 'defaultState', the state at
which the radio returns after an ACK operation, to receive. Transitions from idle will take 100 µs. Turnaround transitions will take 192 µs
and will wait for an ACK for 1000 µs. To load a custom ACK payload, call setAckPayload and setAckLength.
If a packet is received during the ACK window, then the isAck flag for that packet will be true. The ACK windows begins at the end of
the turnaround time and lasts for the timeout length. If auto acknowledgment is not enabled, then the isAck flag will always be false.
To customize ACK functionality, users can use the autoAckPause command to either skip the wait for an ACK on the transmit side or
skip the transmit of an ACK on the receive side. To modify if/how the ACK is transmitted after a receive operation, use the setTxAckOp-tions command.
Conversely, after a transmit operation, waiting for ACK is controlled by the TX options configured by configTxOptions. When combined
with the txWithOptions command, the configuration is honored. However, whenever a simple tx is called, configured options will be
ignored and defaults will be used for the transmit (that is, do not wait for ACK, send CRC, use sync word 0).

Application Features
4.11 RF Energy Sensing
The EFR32 has the ability to sense the presence of RF Energy above -20 dBm within either or both the 2.4 GHz and Sub 1-GHz bands
and trigger an event if that energy is continuously present for certain durations of time.
This feature is exposed through library RAIL_RfSense() and RAIL_RfSensed() APIs, whose use is exemplified by the RAILtest
commands rfSense and sleep. Both commands allow you to specify the duration in microseconds of continuous RF energy, and which
RF band(s) to monitor. The requested duration will be mapped to the nearest duration supported by the hardware; it is not terribly precise
and can be off by a factor of 2 or more. Once RF energy of sufficient duration has been sensed, the sensing operation terminates and a
new one must be started if additional sensing is desired.
The rfSense command activates sensing in the background during normal RAILtest operation, and will report when energy of sufficient
duration has been detected through an asynchronous rfSensedCheck message. Note that sensing energy within a band on EFR32
precludes normal packet reception in that same band; this is by design.
The sleep command allows you to activate RF sensing in combination with entering one of the Energy-Saving Modes EM0..EM4. To
wake from these modes, RF energy of the specified duration and band must be sensed. Energy modes 0 through 3 will also wake and
terminate RF sensing on any serial input to the CLI. EM4 does not support waking on serial input. It will only wake on RF sense or a pin
reset.
Some examples:
RFSENSE Legacy Mode:
> rfSense 500 2 // Sense RF energy of ~0.5ms or longer in sub-GHz band
{{(rfsense)}{RfSense:MHz}{RfUs:413}} // Closest HW supports is ~0.4ms
...
{{(rfSensedCheck)}{RfSensed:MHz}{RfUs:413}}
> sleep 2 500 1 // Sleep in EM2 for RF energy of ~0.5ms in 2.4 GHz band
{{(sleep)}{EM:2}{SerialWakeup:On}{RfSense:GHz}}
...
{{(sleepWoke)}{EM:2}{SerialWakeup:No}{RfSensed:Yes}{RfUs:413}}
> sleep 4 500 3 // Sleep in EM4 for RF energy of ~0.5ms in any band
{{(sleep)}{EM:4s}{SerialWakeup:Off}{RfSense:Any}}
...
{{(reset)}{App:RAILtest}{Built:Jul 19 2019 13:36:24}}
{{(sleepWoke)}{EM:4s}{SerialWakeup:No}{RfSensed:Yes}}
If the multi-timer is never enabled (or subsequently disabled with enableMultiTimer), then the RAIL timer is a single-instance, hard-
ware timer. If the multi-timer is enabled, the RAIL timer becomes one instance of the software-based multi-timer. The multi-timer can only
be enabled or disabled when no timers are running.

Protocol-Specific Features
5 Protocol-Specific Features
5.1 IEEE 802.15.4
RAIL provides IEEE 802.15.4-specific hardware acceleration that can be configured through RAILtest commands. To configure the IEEE
802.15.4 2.4 GHz Radio Configuration, use config2p4GHz802154. This will configure the IEEE 802.15.4 2.4 GHz modem settings as
well as channel scheme, making channels 11-26 available for use. To configure IEEE 802.15.4 hardware acceleration, use the ena-ble802154 command. The options exposed in enable802154 allow you to configure similar parameters as autoAckConfig.
The IEEE 802.15.4 ACK payload is already loaded into the ACK buffer; do not call setAckPayload or setAckLength. However, you
will want to enable the Wait-For-ACK transmit option through configTxOptions so the hardware looks for the specific ACK correspond-
ing to the transmitted packet. RAILtest is configured to always set frame pending bit in the ACK if it successfully receives a data command
to the node. Any ACK modifications should use commands detailed in section 4.10 Auto Acknowledgment.
Further IEEE 802.15.4 configuration is done through acceptFrames, setPromiscuousMode, and setPanCoordinator. To configure
the node's address, use the setPanId802154, setShortAddr802154, or setLongAddr802154 commands. These commands map
very closely to the RAIL API that it wraps, so refer to the RAIL Library doxygen for further information.
From this point, use the normal tx and rx commands to send packets back and forth.

RAIL provides Bluetooth Low Energy (BLE)-specific hardware acceleration. RAILtest provides a few wrappers over these APIs but since
BLE is so timing-critical, not much can be done through RAILtest commands. To enable BLE hardware acceleration, use the setBleMode 1 command. You can then configure channel-specific settings with setBleChannelParams. A preset configuration to enable advertising
on channel 37 is available using the setBleAdvertising command.
RAILtest can output a BLE advertising packet on channel 37 with the following commands:
After these commands, use your phone to search for available Bluetooth devices. You should see 'Silabs RAILTEST' as an available
device. RAILtest is not a connectable device.
5.3 Z-Wave
RAIL provides Z-Wave-specific hardware acceleration that can be configured through RAILtest commands. Users can use the
setZWaveMode command to enter Z-Wave mode and then setZWaveRegion to specify one of the region-specific PHYs, which gener-
ally consist of three separate channels. More about these PHYs can be found in ITU-T G.9959. In order to send packets between nodes,
the following commands must be entered on both nodes, using the same region.
RX Node:
// Turn the radio off first in order to configure it
> rx 0
{{(rx)}{Rx:Disabled}{Idle:Enabled}{Time:99647646}}
// Enable Z-Wave Mode (1) – beam detection enabled (0x2), promiscuous mode off (0x1)
> setzwavemode 1 2
{{(setZWaveMode)}{ZWAVE:Enabled}{Promiscuous:Disabled}{BeamDetect:Enabled}}
// Specify the EU Region
> setzwaveregion 0
{{(setZWaveRegion)}{ZWaveRegion:EU-European Union}{ZWaveRegionIndex:0}}
On the transmit side, the user must specify the correct Home ID of the target Z-Wave node. This can be skipped, however, by enabling
promiscuous mode on the receiver via setZWaveMode and/or setZWaveOptions. Additionally, the user must specify an accurate length
byte, otherwise the transmitter may encounter an underflow. The CRC will be calculated on the fly by the radio hardware, so there is no
need to specify it explicitly.

UG409: RAILtest User's Guide
Protocol-Specific Features
TX Node:
// Specify the Home ID in the packet. This is a 4-byte value, starting at byte 0
> setTxPayload 0 0xCA 0xFE 0xC0 0xDE
{{(setTxPayload)}{len:16}{payload: 0xca 0xfe 0xc0 0xde 0x33 0x44 0x55 0x66 0x77 0x88 0x99 0xaa 0xbb
0xcc 0xdd 0xee}}
// Specify the length byte (byte 7) for a packet
> setTxPayload 7 15
{{(setTxPayload)}{len:16}{payload: 0xca 0xfe 0xc0 0xde 0x33 0x44 0x55 0x0f 0x77 0x88 0x99 0xaa 0xbb
0xcc 0xdd 0xee}}
On the receiver side, for basic functionality, the node must configure its own Home ID. Note that this will set parameters for the node on
which these commands are executed – they do not set the TX packet contents for outgoing packets. To skip Home ID configuration,
promiscuous mode can also be enabled.
RX Node:
// The Home ID is CAFEC0DE, using a “don’t care” hash
setzwavehomeid 0xCAFEC0DE 0x55
{{(setZWaveHomeId)}{Status:Set}}
For more advanced receiver functionality, or to be used as a sniffer, channel hopping must be configured. As used in Z-Wave networks,
the three channels in each of the Z-Wave regions can be used in rapid succession for different purposes. For a receiving node to be able
to receive these packets on any arbitrary channel, the node uses hardware acceleration to hop through the three different channels at
specific intervals, using preamble sense mode. The following specification configures the correct hopping scheme, with the on-channel
time and preamble sense mode, as well as zero delay between channels. Note, that while this configuration is accurate for most regions,
Japan and Korea regions use 270 µs for all the channels, instead of the 270, 450, and 560 specified below. After this, packets can be
transmitted on channel 0, 1, or 2, and will be received on the receiver node, without having explicitly set the channel.

Testing Modes
6 Testing Modes
6.1 Packet Error Rate Testing
RAILtest can be used to determine the packet error rate (PER) for a given setup. To set up this test, a piece of test equipment needs to
be configured to send a packet on the rising edge of a GPIO. The specific EFR32 pin and port to be used are identified by the defines
PER_PIN and PER_PORT (RAILtest 2.8) or defines SL_RAIL_TEST_PER_PIN and SL_RAIL_TEST_PER_PORT (RAILtest 2.9). perRx
100 10000 configures the Packet Error Rate test to send 100 packets, waiting 10000 µs between each packet. At the end of the test, the app provides an output indicating that Per mode has finished, and the statistics on the test can be recovered with perStatus and
status. Calling perRx 0 0 cancels an ongoing test, and calling perRx has the same effect as calling resetCounters.
6.2 Bit Error Rate Testing
The EFR32 hardware can enter bit error rate (BER) receive mode for diagnostic purposes. In BER mode, the chip expects to receive a
PN9 (x^9 + x^5 + 1) transmission. In order to run the BER test successfully, a radio configuration specific to BER mode must be generated
by the radio configurator.
Use the setBerConfig command to specify how many bytes to receive in BER receive mode. The maximum number of bytes is
536870911. Specifying 0 or a number greater than the maximum possible value automatically configures the BER test to receive the
maximum number of bytes for testing.
Use the berRx command to enter or exit BER receive mode. If the test is allowed to run to completion, there is no need to exit BER
receive mode.
Use the berStatus command to query for test statistics during or after a test. The statistics are reset when setBerConfig is run or
when berRx 1 is run. The statistics include:
• BitsToTest (total bits to be tested)
• BitsTested (the number of bits already received and tested)
• PercentDone (percentage of how many configured bytes have been received)
• RSSI (an instantaneous RSSI value corresponding to the last byte received)
• BitErrors (the number of received bits determined to be in error)
• PercentBitError (percentage of bit errors to bits tested)

7 Miscellaneous
7.1 RAM Modem Reconfiguration
RAILtest can dynamically change the modem configuration allowing for a quick evaluation of different protocols or settings without the
need to compile or flash the chip. This is enabled through the writeRmrStructure, updateConfigurationPointer and recon-figureModem commands. These commands are intended to be used only by Simplicity Studio and not directly from the CLI.
7.2 Register/Memory Access
Note: These commands provide direct access to the chip's address space. Writing a value to an address can change RAM and register
values, and even reading from an address can change the operation of the chip. Any action taken with these commands will
potentially conflict with the running program, possibly leading to unexpected behavior or a system crash. Only use these commands when instructed to do so by your Silicon Labs support contact.
To modify any memory on the system use the getmemw and setmemw commands. To use getmemw specify the starting address and
the number of 32bit words you want to read. Using setmemw is slightly different in that you specify the starting address and the 32bit
words to write starting at the specified address. These commands operate on 32bit words so all addresses must be 32bit aligned.
7.3 Debug
• To output a tone on the current channel (or overridden frequency) use the setTxTone command.
• To output a PN9 or 101010 stream on the current channel on a certain antenna, TX_ANTENNA0 or TX_ANTENNA1, use the setTx-
Stream command.
