| Command | Description
|

|---------|------------
|
||||
| `rtl_433` | Will run the software in receive mode. Some sensor data can be received and decoded.
|
||||
| `rtl_433` | Default receive mode, attempt to decode all known devices
|
||||
| `rtl_433 -p NN -R 1 -R 9 -R 36 -R 40 | Typical usage: Enable device decoders for desired devices. Correct rtl-sdr tuning error (ppm offset).
|
||||
| `rtl_433 -a` | Will run in analyze mode and you will get a text description of the received signal.
|
||||
| `rtl_433 -A` | Enable pulse analyzer. Summarizes the timings of pulses, gaps, and periods. Can be used in either the normal decode mode, or analyze mode.
|
||||
| `rtl_433 -a -t` | Will run in analyze mode and save a test file per detected signal (gfile###.data). Format is uint8, 2 channels.
