Save recorded data with hackRF to a .raw file

HackRF receives data at a very high speed. It produces about 1GB data within 40 seconds of recording. These data can be saved to a file, to process later. I use the .raw file format here.

The file can be created separately in .raw format and use a flow graph to record data. But the easiest way is to use the following command which creates the file and save data in one command.

hackrf_transfer -r .raw -f  433000000 -s 20000000

Further info about hackRF_transfer command:
                     about naming a file:
You can use CTRL+C to stop recording data.


Flow graph method:

Waterfall Sink block allows us to see live data being recorded by HackRF and File Sink block saves data to the file named.
