Communication Protocol

The ME218C Communications Protocol outlines the structured communication between the NEDMO and ØILUS using XBee radio modules. The protocol defines specific frame structures for transmitting and receiving data, ensuring reliable control and status updates during gameplay. Each frame consists of a start delimiter, length, API identifier, destination address, options, RF data, and a checksum. The key commands include pairing, control, fuel status, and refueling, with designated message IDs for each. Pairing is initiated by the NEDMO, which sends a request to the ØILUS, and the ØILUS responds with an acknowledgment. Control messages are sent at a frequency of 5 Hz, containing thrust and rudder control information. Fuel status messages indicate the current fuel level of the ØILUS, and refueling messages increment the fuel level based on continuous large-scale movements. The protocol ensures robust and synchronized operation between the NEDMO and ØILUS, crucial for effective gameplay and system integration.
