Makes Chuango less noisy Has provision for replacing ternary encoder (implements sync) Can be expanded to include more selectivity (e.g. gap timing) Can be expanded to include start bit removal (for replacing RAW)
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.
