The Universal Radio Hacker comes with a Command Line Interface (CLI) to automate certain tasks easier. For example, you could install URH on a Raspberry Pi, attach a SDR to it, throw it in some corner and let it sniff the wireless traffic for a while.
After installation, the CLI (urh_cli.py / urh_cli.exe on Windows) will be located inside your installation folder. If you run URH from source you can find it in urh/cli/urh_cli.py.
The CLI comes with an extensive built in help, which you can access with -h or --help.
$ ./cli/urh_cli.py --help
usage: urh_cli.py [-d DEVICE] [-di DEVICE_IDENTIFIER] [-db {native,gnuradio}]
[-f FREQUENCY] [-s SAMPLE_RATE] [-b BANDWIDTH] [-g GAIN]
[-if IF_GAIN] [-bb BASEBAND_GAIN] [-a]
[-fcorr FREQUENCY_CORRECTION] [-cf CARRIER_FREQUENCY]
[-ca CARRIER_AMPLITUDE] [-cp CARRIER_PHASE] [-mo MOD_TYPE]
[-bps BITS_PER_SYMBOL] [-pm PARAMETERS [PARAMETERS ...]]
[-sps SAMPLES_PER_SYMBOL] [-bl BIT_LENGTH] [-n NOISE]
[-c CENTER] [-cs CENTER_SPACING] [-t TOLERANCE] [--hex]
[-e ENCODING] [-m MESSAGES [MESSAGES ...]] [-file FILENAME]
[-p PAUSE] [-rx] [-tx] [-rt RECEIVE_TIME] [-r] [-h] [-v]
[project_file]
This is the Command Line Interface for the Universal Radio Hacker.
positional arguments:
project_file
Software Defined Radio Settings:
Configure Software Defined Radio options
-d DEVICE, --device DEVICE
Choose a Software Defined Radio. Allowed values are
AirSpy R2, AirSpy Mini, BladeRF, FUNcube, HackRF,
LimeSDR, PlutoSDR, RTL-SDR, RTL-TCP, SDRPlay,
SoundCard, USRP
-di DEVICE_IDENTIFIER, --device-identifier DEVICE_IDENTIFIER
-db {native,gnuradio}, --device-backend {native,gnuradio}
-f FREQUENCY, --frequency FREQUENCY
Center frequency the SDR shall be tuned to
-s SAMPLE_RATE, --sample-rate SAMPLE_RATE
Sample rate to use
-b BANDWIDTH, --bandwidth BANDWIDTH
Bandwidth to use (defaults to sample rate)
-g GAIN, --gain GAIN RF gain the SDR shall use
-if IF_GAIN, --if-gain IF_GAIN
IF gain to use (only supported for some SDRs)
-bb BASEBAND_GAIN, --baseband-gain BASEBAND_GAIN
Baseband gain to use (only supported for some SDRs)
-a, --adaptive-noise Use adaptive noise when receiving.
-fcorr FREQUENCY_CORRECTION, --frequency-correction FREQUENCY_CORRECTION
Set the frequency correction for SDR (if supported)
Modulation/Demodulation settings:
Configure the Modulator/Demodulator. Not required in raw mode.In case of
RX there are additional demodulation options.
-cf CARRIER_FREQUENCY, --carrier-frequency CARRIER_FREQUENCY
Carrier frequency in Hertz (default: 1000.0)
-ca CARRIER_AMPLITUDE, --carrier-amplitude CARRIER_AMPLITUDE
Carrier amplitude (default: 1)
-cp CARRIER_PHASE, --carrier-phase CARRIER_PHASE
Carrier phase in degree (default: 0)
-mo MOD_TYPE, --modulation-type MOD_TYPE
Modulation type must be one of ASK, FSK, PSK, GFSK,
OQPSK (default: FSK)
-bps BITS_PER_SYMBOL, --bits-per-symbol BITS_PER_SYMBOL
Bits per symbol e.g. 1 means binary modulation
(default: 1).
-pm PARAMETERS [PARAMETERS ...], --parameters PARAMETERS [PARAMETERS ...]
Parameters for modulation. Separate with spaces
-sps SAMPLES_PER_SYMBOL, --samples-per-symbol SAMPLES_PER_SYMBOL
Length of a symbol in samples (default: 100).
-bl BIT_LENGTH, --bit-length BIT_LENGTH
Same as samples per symbol, just there for legacy
support (default: 100).
-n NOISE, --noise NOISE
Noise threshold (default: 0.1). Used for RX only.
-c CENTER, --center CENTER
Center between symbols for demodulation (default: 0).
Used for RX only.
-cs CENTER_SPACING, --center-spacing CENTER_SPACING
Center spacing between symbols for demodulation
(default: 0.1). Value has only effect for modulations
with more than 1 bit per symbol. Used only for RX.
-t TOLERANCE, --tolerance TOLERANCE
Tolerance for demodulation in samples (default: 5).
Used for RX only.
Data configuration:
Configure which data to send or where to receive it.
--hex Give messages as hex instead of bits
-e ENCODING, --encoding ENCODING
Specify encoding
-m MESSAGES [MESSAGES ...], --messages MESSAGES [MESSAGES ...]
Messages to send. Give pauses after with a /. Separate
with spaces e.g. 1001/42ms 1100/3ns 0001 1111/200. If
you give no time suffix after a pause it is assumed to
be in samples.
-file FILENAME, --filename FILENAME
Filename to read messages from in send mode. In
receive mode messages will be written to this file
instead to STDOUT.
-p PAUSE, --pause PAUSE
The default pause which is inserted after a every
message which does not have a pause configured.
(default: 250ms) Supported time units: s (second), ms
(millisecond), µs (microsecond), ns (nanosecond) If
you do not give a time suffix the pause is assumed to
be in samples.
-rx, --receive Enter RX mode
-tx, --transmit Enter TX mode
-rt RECEIVE_TIME, --receive-time RECEIVE_TIME
How long to receive messages. (default: 3.0) Any
negative value means infinite.
-r, --raw Use raw mode i.e. send/receive IQ data instead of
bits.
Miscellaneous options:
-h, --help show this help message and exit
-v, --verbose
Here is an example which uses the URH CLI to send to messages to a wireless socket. The first messages switches the socket on. After 500ms the second message switches the socket off.
$ urh_cli.py -d HackRF -f 868.3e6 -s 2e6 -g 0 -if 30 -cf 3.906e3 -mo ASK -sps 16 -p0 0 -p1 1 -m aad3d5ddddcc5d45ddbba000000/500ms aad3c5ddddcc5d45ddbaa00000000 --pause 10s -tx --hex -e "'WSP', 'Wireless Short Packet (WSP)'"
