DESCRIPTION

       The bladeRF-cli utility is used to flash firmware files, load FPGA bitstreams, and perform other tasks on
       the nuand bladeRF software-defined radio system.

       For more information  on  obtaining  or  building  firmware  files  and  FPGA  bitstreams,  please  visit
       http://nuand.com/.

       bladeRF command line interface and test utility (1.3.1-0.2016.01~rc1-3)

OPTIONS

-d, --device <device>
Use the specified bladeRF device.

-f, --flash-firmware <file>
Write the provided FX3 firmware file to flash.

-l, --load-fpga <file>
Load the provided FPGA bitstream.

-L, --flash-fpga <file>
Write the provided FPGA image to flash for autoloading. Use -L X or --flash-fpga X to disable FPGA
autoloading.

-p, --probe
Probe for devices, print results, then exit. A non-zero return status will be returned if no
devices are available.

-e, --exec <command>
Execute the specified interactive mode command. Multiple -e flags may be specified. The commands
will be executed in the provided order.

-s, --script <file>
Run provided script.

-i, --interactive
Enter interactive mode.

--lib-version
Print libbladeRF version and exit.

-v, --verbosity <level>
Set the libbladeRF verbosity level. Levels, listed in increasing verbosity, are:

critical, error, warning,
info, debug, verbose

--version
Print CLI version and exit.

-h, --help
Show this help text.

--help-interactive
Print help information for all interactive commands.

Notes:
The -d option takes a device specifier string. See the bladerf_open() documentation for more
information about the format of this string.

If the -d parameter is not provided, the first available device will be used for the provided
command, or will be opened prior to entering interactive mode.

Commands are executed in the following order:

Command line options, -e <command>, script commands, interactive mode commands.

When running 'rx/tx start' from a script or via -e, ensure these commands are later followed by
'rx/tx wait [timeout]' to ensure the program will not attempt to exit before
reception/transmission is complete.

INTERACTIVE COMMANDS

bladeRF-cli supports a scriptable interactive mode. Run bladeRF-cli --interactive to enter this mode.
Type "help" for a listing of all commands, or "help <command>" for more information about <command>.

calibrate
Usage: calibrate <operation> [options]

Perform the specified transceiver calibration operation.

Available operations:

• LMS internal DC offset auto-calibrations

• calibrate lms [show]

• calibrate lms tuning [value]

• calibrate lms rxlpf [<I filter> <Q filter>]

• calibrate lms rxvga2 [<DC ref> <I1> <Q1> <I2> <Q2>]

Perform the specified auto-calibration, or all of them if none are provided. When values are provided,
these are used instead of the results of the auto-calibration procedure. Use lms show to read and
print the current LMS calibration values.

For rxvga2, I1 and Q1 are the Stage 1 I and Q components respectively, and I2 and Q2 are the Stage 2 I
and Q components.

• RX and TX I/Q DC offset correction parameter calibration

• calibrate dc <rx|tx> [<I> <Q>]

• calibrate dc <rxtx>

Calibrate the DC offset correction parameters for the current frequency and gain settings. If a I/Q

jump_to_boot
Usage: jump_to_boot

Clear out a FW signature word in flash and jump to FX3 bootloader.

The device will continue to boot into the FX3 bootloader across power cycles until new firmware is
written to the device.

load
Usage: load <fpga|fx3> <filename>

Load an FPGA bitstream or program the FX3's SPI flash.

xb
Usage: xb <board_model> <subcommand> [parameters]

Enable or configure an expansion board.

Valid values for board_model:

• 100

XB-100 GPIO expansion board

• 200

XB-200 LF/MF/HF/VHF transverter expansion board

Common subcommands:

• enable

Enable the XB-100 or XB-200 expansion board.

XB-200 subcommands:

• filter [rx|tx] [50|144|222|custom|auto_1db|auto_3db]

Selects the specified RX or TX filter on the XB-200 board. Below are descriptions of each of the
filter options.

• 50

Select the 50-54 MHz (6 meter band) filter.

• 144

Select the 144-148 MHz (2 meter band) filter.

• 222

Select the 222-225 MHz (1.25 meter band) filter. Realistically,
this filter option is actually slightly wider, covering
206 MHz - 235 MHz.

• custom

Selects the custom filter path. The user should connect a filter
along the corresponding FILT and FILT-ANT connections when using
this option. Alternatively one may jumper the FILT and FILT-ANT
connections to achieve "no filter" for reception. (However, this is
_highly_ discouraged for transmissions.)

• auto_1db

Automatically selects one of the above choices based upon frequency
and the filters' 1dB points. The custom path is used for cases
that are not associated with the on-board filters.

• auto_3db

Automatically selects one of the above choices based upon frequency
and the filters' 3dB points. The custom path is used for cases
that are not associated with the on-board filters.

Examples:

• xb 200 enable

Enables and configures the XB-200 transverter expansion board.

• xb 200 filter rx 144

Selects the 144-148 MHz receive filter on the XB-200 transverter expansion board.

mimo
Usage: mimo [master | slave]

Modify device MIMO operation.

open
Usage: open [device identifiers]

Open the specified device for use with successive commands. Any previously opened device will be closed.

The general form of the device identifier string is:

<backend>:[device=<bus>:<addr>] [instance=<n>] [serial=<serial>]

See the bladerf_open() documentation in libbladeRF for the complete device specifier format.

peek
Usage: peek <dac|lms|si> <address> [num_addresses]

The peek command can read any of the devices hanging off the FPGA which includes the LMS6002D
transceiver, VCTCXO trim DAC or the Si5338 clock generator chip.

If num_addresses is supplied, the address is incremented by 1 and another peek is performed for that many
addresses.

specified, all parameters are printed.

Parameter Description
────────────────────────────────────────────────────────────────────────
bandwidth Bandwidth settings
frequency Frequency settings
gpio FX3 <-> FPGA GPIO state
loopback Loopback settings

xb_gpio Expansion board GPIO values
xb_gpio_dir Expansion board GPIO direction (1=output, 0=input)

probe
Usage: probe [strict]

Search for attached bladeRF device and print a list of results.

Without specifying strict, the lack of any available devices is not considered an error.

When provided the optional strict argument, this command will treat the situation where no devices are
found as an error, causing scripts or lists of commands provided via the -e command line argument to
terminate immediately.

quit
Usage: quit

Exit the CLI.

recover
Usage: recover [<bus> <address> <firmware file>]

Load firmware onto a device running in bootloader mode, or list all devices currently in bootloader mode.

With no arguments, this command lists the USB bus and address for FX3-based devices running in bootloader
mode.

When provided a bus, address, and path to a firmware file, the specified device will be loaded with and
begin executing the provided firmware.

In most cases, after successfully loading firmware into the device's RAM, users should open the device
with the "open" command, and write the firmware to flash via "load fx3 <firmware file>"

run
Usage: run <script>

Run the provided script.

rx
Usage: rx <start | stop | wait | config [param=val [param=val [...]]>

Receive IQ samples and write them to the specified file. Reception is controlled and configured by one
of the following:

Command Description
────────────────────────────────────────────────────────────────────────
start Start receiving samples
stop Stop receiving samples
wait Wait for sample transmission to complete, or until a
specified amount of time elapses
config Configure sample reception. If no parameters are
provided, the current parameters are printed.

Running rx without any additional commands is valid shorthand for rx config.

The wait command takes an optional timeout parameter. This parameter defaults to units of milliseconds
(ms). The timeout unit may be specified using the ms or s suffixes. If this parameter is not provided,
the command will wait until the reception completes or Ctrl-C is pressed.

Configuration parameters take the form param=value, and may be specified in a single or multiple
rx config invocations. Below is a list of available parameters.

Parameter Description
────────────────────────────────────────────────────────────────────────
n Number of samples to receive. 0 = inf.
file Filename to write received samples to
format Output file format. One of the following:
csv: CSV of SC16 Q11 samples
bin: Raw SC16 Q11 DAC samples
samples Number of samples per buffer to use in the
asynchronous stream. Must be divisible by 1024 and
>= 1024.
buffers Number of sample buffers to use in the asynchronous
stream. The min value is 4.
xfers Number of simultaneous transfers to allow the
asynchronous stream to use. This should be less
than the buffers parameter.
timeout Data stream timeout. With no suffix, the default
unit is ms. The default value is 1000 ms (1 s).
Valid suffixes are ms and s.

Example:

• rx config file=/tmp/data.bin format=bin n=10K

Receive (10240 = 10 * 1024) samples, writing them to /tmp/data.bin in the binary DAC format.

Notes:

• The n, samples, buffers, and xfers parameters support the suffixes K, M, and G, which are multiples of
1024.

• An rx stop followed by an rx start will result in the samples file being truncated. If this is not
desired, be sure to run rx config to set another file before restarting the rx stream.

• For higher sample rates, it is advised that the binary output format be used, and the output file be
written to RAM (e.g. /tmp, /dev/shm), if space allows. For larger captures at higher sample rates,
consider using an SSD instead of a HDD.

tx
Usage: tx <start | stop | wait | config [parameters]>

Read IQ samples from the specified file and transmit them. Transmission is controlled and configured by
one of the following:

Command Description
────────────────────────────────────────────────────────────────────────
start Start transmitting samples
stop Stop transmitting samples
wait Wait for sample transmission to complete, or until a
specified amount of time elapses

config Configure sample transmission. If no parameters are
provided, the current parameters are printed.

Running tx without any additional commands is valid shorthand for tx config.

Configuration parameters take the form param=value, and may be specified in a single or multiple
tx config invocations. Below is a list of available parameters.

Parameter Description
────────────────────────────────────────────────────────────────────────
file Filename to read samples from
format Input file format. One of the following:
csv: CSV of SC16 Q11 samples ([-2048, 2047])
bin: Raw SC16 Q11 DAC samples ([-2048, 2047])
repeat The number of times the file contents should be
transmitted. 0 implies repeat until stopped.
delay The number of microseconds to delay between
retransmitting file contents. 0 implies no delay.
samples Number of samples per buffer to use in the
asynchronous stream. Must be divisible by 1024 and
>= 1024.
buffers Number of sample buffers to use in the asynchronous
stream. The min value is 4.
xfers Number of simultaneous transfers to allow the
asynchronous stream to use. This should be < the
buffers parameter.
timeout Data stream timeout. With no suffix, the default
unit is ms. The default value is 1000 ms (1 s).
Valid suffixes are 'ms' and 's'.

Example:

• tx config file=data.bin format=bin repeat=2 delay=250000

Transmitting the contents of data.bin two times, with a ~250ms delay between transmissions.

Notes:

• The n, samples, buffers, and xfers parameters support the suffixes K, M, and G, which are multiples of
1024.

• For higher sample rates, it is advised that the input file be stored in RAM (e.g. /tmp, /dev/shm) or
on an SSD, rather than a HDD.

• When providing CSV data, this command will first convert it to a binary format, stored in a file in the
current working directory. During this process, out-of-range values will be clamped.

• When using a binary format, the user is responsible for ensuring that the provided data values are
within the allowed range. This prerequisite alleviates the need for this program to perform range
checks in time-sensitive callbacks.

set
Usage: set <parameter> <arguments>

The set command takes a parameter and an arbitrary number of arguments for that particular parameter.
The parameter is one of:

rx_mux FPGA RX FIFO input mux mode. Options are:
BASEBAND_LMS, 12BIT_COUNTER, 32BIT_COUNTER,
DIGITAL_LOOPBACK
rxvga1 Gain setting of RXVGA1, in dB. Range: [5, 30]
rxvga2 Gain setting of RXVGA2, in dB. Range: [0, 30]
txvga1 Gain setting of TXVGA1, in dB. Range: [-35, -4]
txvga2 Gain setting of TXVGA2, in dB. Range: [0, 25]
sampling External or internal sampling mode
samplerate Sample rate settings
trimdac VCTCXO trim DAC settings
vctcxo_tamer VCTCXO tamer mode. Options: Disabled, 1PPS, 10MHz
xb_gpio Expansion board GPIO values
xb_gpio_dir Expansion board GPIO direction (1=output, 0=input)

version
Usage: version

Prints version information for host software and the current device.
