Some test data files have too few "idle" samples at the end to ensure end of packet is robustly detected. Decode an extra empty buffer to ensure decoders are flushed.
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: [-d device index (default: 0)]
[-g gain (default: 0 for auto)]
[-a analyze mode, print a textual description of the signal]
[-t signal auto save, use it together with analyze mode (-a -t)
[-l change the detection level used to determine pulses (0-3200) default: 10000]
[-f [-f...] receive frequency[s], default: 433920000 Hz]
[-s sample rate (default: 250000 Hz)]
[-S force sync output (default: async)]
[-r read data from file instead of from a receiver]
[-p ppm_error (default: 0)]
[-r test file name (indata)]
[-m test file mode (0 rtl_sdr data, 1 rtl_433 data)]
[-D print debug info on event]
[-z override short value]
[-x override long value]
[-R listen only for the specified remote device (can be used multiple times)]

Examples:
| Command | Description |
|---|---|
rtl_433 -a |
will run in analyze mode and you will get a text log of the received signal. |
rtl_433 -a file_name |
will save the demodulated signal in a file. The format of the file is 48kHz 16 bit samples. |
rtl_433 |
will run the software in receive mode. Some sensor data can be receviced. |
This software is mostly useable for developers right now.
