When recording the tool will act as radar client and once connected to a client it will initiate the transfer of raw radar data and record this to a file of disk. This file will include configuration and health data alongside the raw FFT data.
When operating in playback mode, the tool will mimic a radar and act as a TCP Server. Other client applications can connect to the tool and receive data over the network in exactly the same way they would if connected to a real radar.
For a detailed description of the file format used by the tool to record the radar data please refer to Colossus File Format.
