IsoTpFunctionalResponse Class¶
A single ISO-TP PDU received from one ECU in response to a functional (1:N) request.
Inheritance Object → IsoTpFunctionalResponse
Remarks¶
Functional addressing is a broadcast mechanism (ISO 15765-2 §9): the tester transmits a Single Frame on the shared functional CAN identifier, and each ECU that recognises the request replies on its own physical response CAN identifier. One IsoTpFunctionalResponse is produced for every Single-Frame response that arrives within the collection window; multi-frame responses cannot be reassembled in functional addressing (no physical response address to send Flow Control to) and are dropped by the collector.
