[INTERACTIVE COMMANDS]

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>]`
     * `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> dc`

    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
    2 MHz steps.

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]`

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 `bin`ary 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.
