rtl_433

rtl_433 turns your Realtek RTL2832 based DVB dongle into a 433.92MHz generic data receiver

Installation instructions:

Compiling rtl_433 requires rtl-sdr to be installed.

Installation using cmake:

cd rtl_433/
mkdir build
cd build
cmake ../
make
make install

Installation using autoconf:

cd rtl_433/
autoreconf --install
./configure
make
make install

Running:

rtl_433 -h

Usage:	= Tuner options =
	[-d <device index>] (default: 0)
	[-g <gain>] (default: 0 for auto)
	[-f <frequency>] [-f...] Receive frequency(s) (default: 433920000 Hz)
	[-p <ppm_error>] (default: 0)
	[-s <sample rate>] Set sample rate (default: 250000 Hz)
	[-S] Force sync output (default: async)
	= Demodulator options =
	[-R <device>] Listen only for the specified remote device (can be used multiple times)
	[-l <level>] Change detection level used to determine pulses [0-32767] (default: 8000)
	[-z <value>] Override short value in data decoder
	[-x <value>] Override long value in data decoder
	= Analyze/Debug options =
	[-a] Analyze mode. Print a textual description of the signal. Disables decoding
	[-A] Pulse Analyzer. Enable pulse analyzis and decode attempt
	[-D] Print debug info on event (repeat for more info)
	= File I/O options =
	[-t] Test signal auto save. Use it together with analyze mode (-a -t). Creates one file per signal
		 Note: Saves raw I/Q samples (uint8, 2 channel). Preferred mode for generating test files
	[-r <filename>] Read data from input file instead of a receiver
	[-m <mode>] Data file mode for input / output file (default: 0)
		 0 = Raw I/Q samples (uint8, 2 channel)
		 1 = AM demodulated samples (int16)
		 2 = FM demodulated samples (int16) (experimental)
		 Note: If output file is specified, input will always be I/Q
	[<filename>] Save data stream to output file (a '-' dumps samples to stdout)

Examples:

Command	Description
rtl_433	Will run the software in receive mode. Some sensor data can be received and decoded.
rtl_433 -a	Will run in analyze mode and you will get a text description of the received signal.
rtl_433 -a -t	Will run in analyze mode and save a test file per detected signal (gfile###.data). Format is uint8, 2 channels.
rtl_433 -r file_name	Will run with a saved test file as input data.
rtl_433 file_name	Will save the received signal data stream in a file (file may become large).

This software is mostly useable for developers right now.
