Protocol

This integration communicates with the Canton Smart Connect 5.1 via a proprietary binary protocol (FFAA) on TCP port 50006. Each frame starts with the magic bytes FF AA followed by a command ID, type byte, length, and data payload. The protocol was reverse-engineered from network captures of the official Canton App.
