    Interface IJ1939Client

    J1939 Client Interface

    This is the primary SDK interface. All methods must be implemented by both JS and Python SDKs with identical semantics.

    interface IJ1939Client {
        connect(): Promise<void>;
        disconnect(): Promise<void>;
        getSourceAddress(): number;
        isConnected(): boolean;
        onPGN(pgn: number, handler: PGNHandler): () => void;
        requestPGN(pgn: number, destination?: number): Promise<void>;
        sendPGN(pgn: number, data: PGNData, destination?: number): Promise<void>;
    }
