              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 txlpf [<I filter> <Q filter>]

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

         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 values  are  provided,  they  are  applied  directly.   cal rxtx  is
         shorthand for cal rx followed by cal tx.

       · RX and TX I/Q balance correction parameter calibration

         · calibrate iq <rx|tx> <gain|phase> <value>

         Set the specified IQ gain or phase balance parameters.

       · Generate RX or TX I/Q DC correction parameter tables

         · calibrate table dc <rx|tx> [<f_min> <f_max> [f_inc]]

         Generate  and  write an I/Q correction parameter table to the current working directory,
         in a file named <serial>_dc_<rx|tx>.tbl.  f_min and f_max are min and max frequencies to
         include in the table.  f_inc is the frequency increment.

         By default, tables are generated over the entire frequency range, in 10 MHz steps.

       · Generate RX or TX I/Q DC correction parameter tables for AGC Look Up Table

         · calibrate table agc <rx|tx> [<f_min> <f_max> [f_inc]]

         Similar  usage  as  calibrate table dc  except the call will set gains to the AGC's base
         gain value before running calibrate table dc.

         XB-100 GPIO expansion board

       · 200

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

       · 300

         XB-300 amplifier board

       Common subcommands:

       · enable

         Enable the XB-100, XB-200, or XB-300 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.

       XB-300 subcommands:

       · <pa|lna|aux> [on|off]

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

         Note: The auxiliary 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.

       · xb 300 enable

         Enables  and  configures  the  use of GPIOs to interact with the XB-300.  The PA and LNA
         will disabled by default.

       · xb 300 lna on

         Enables the RX LNA on the XB-300.  LED  D1  (green)  is  illuminated  when  the  LNA  is
         enabled, and off when it is disabled.

       · xb 300 pa off

         Disables  the TX PA on the XB-300.  LED D2 (blue) is illuminated when the PA is enabled,
         and off when it is disabled.

   mimo
       Usage: mimo [master | slave]

       Modify device MIMO operation.

       IMPORTANT: This command is deprecated and has  been  superseded  by  "print/set smb_mode".
       For usage text, run: "set smb_mode"

   open
       Usage: open [device identifiers]

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

       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.

       Valid Address Ranges:

       Device   Address Range

   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
       ────────────────────────────────────────────────────────────────────────

                          >= 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.

   trigger
       Usage: trigger [<trigger> <tx | rx> [<off slave master fire>]]

       If used without parameters, this command prints the state of all triggers.  When aand  and
       supplied, the specified trigger is printed.

       Below are the available options for :

            Trigger   Description
       ────────────────────────────────────────────────────────────────────────
              J71-4   Trigger signal is on mini_exp1 (J71, pin 4).

       The  trigger is controlled and configured by providing the last argument, which may be one
       of the following:

            Command   Description
       ────────────────────────────────────────────────────────────────────────
                off   Clears fire request and disables trigger functionality.
              slave   Configures trigger as slave, clears  fire  request,  and
                      arms the device.
             master   Configures  trigger  as master, clears fire request, and
                      arms the device.
               fire   Sets fire request.  Only applicable to the master.

       A trigger chain consists of a single or multiple bladeRF units and may contain TX  and  RX
       modules.   If  multiple  bladeRF  units  are used they need to be connected via the signal
       specified by and a common ground.

       The following sequence of commands should be used to ensure proper synchronization.  It is
       assumed that all triggers are off initially.

       1. Configure designated trigger master

           IMPORTANT

                  Never configure two devices as trigger masters on a single chain.
                  Contention on the same signal could damage the devices.

       2. Configure all other devices as trigger slaves

       3. Configure and start transmit or receive streams.

                  The operation will stall until the triggers fire. As such, sufficiently
                  large timeouts should be used to allow the trigger signal to be emitted
                  by the master and received by the slaves prior to libbladeRF returning
                  BLADERF_ERR_TIMEOUT.

       4. Set fire-request on master trigger

                  All devices will synchronously start transmitting or receiving data.

       5. Finish the transmit and receive tasks as usual

       6. Re-configure the master and slaves to clear fire requests and re-arm.

                  Steps 1 through 5 may be repeated as necessary.

       7. Disable triggering on all slaves

       8. Disable triggering on master

       Notes:

       · Synchronizing  transmitters  and  receivers on a single chain will cause an offset of 11
         samples between TX and RX; these  samples  should  be  discarded.   This  is  caused  by
         different processing pipeline lengths of TX and RX.  This value might change if the FPGA
         code is updated in the future.

   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
