DoIP Protocol - ISO 13400-2
• Transport: TCP (diagnostic), UDP (discovery, port 13400)
• Header (8 bytes): Protocol Version (1B) + Inverse (1B) + Payload Type (2B) + Payload Length (4B)
• Discovery: UDP broadcast → Vehicle Identification Response with VIN, EID, GID
• Routing Activation: TCP → SA + Activation Type → Response with code
• Diagnostic: DoIP header + SA (2B) + TA (2B) + UDS payload
• Timing: T_TCP_General=5s, T_TCP_Initial=2s, T_Alive=500ms
• Version: 0x02=ISO 13400-2:2012, 0x03=ISO 13400-2:2019
