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>.

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.

XB-300 subcommands:

•

<pa|lna|aux> [on|off]

Enable or disable the power amplifier (PA), low-noise amplifier (lna) or auxillary LNA (aux). The current state if the specified device is printed if [on|off] is not specified.

Note: The auxillary path on the XB-300 is not populated with components by default; the aux control will have no effect upon the RX signal. This option is available for users to modify their board with custom hardware.

•

<pwr>

Read the current Power Detect (PDET) voltage and compute the output power.

•

trx <rx|tx>

The default XB-300 hardware configuration includes separate RX and TX paths. However, users wishing to use only a single antenna for TRX can do so via a modification to resistor population options on the XB-300 and use this command to switch between RX an TX operation. (See R8, R10, and R23 on the schematic.)

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.

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

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.

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 transmission completes or Ctrl-C is pressed.

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:

Parameter	Description
bandwidth	Bandwidth settings
frequency	Frequency settings
gpio	FX3 <-> FPGA GPIO state
loopback	Loopback settings. Run 'set loopback' to list modes.
lnagain	Gain setting of the RX LNA, in dB. Values: 0, 3, 6
