SegmentAck (Clause 20.1.6)
ErrorPdu (Clause 20.1.7)
RejectPdu (Clause 20.1.8)
AbortPdu (Clause 20.1.9)

Structs§

AbortPdu: Abort PDU (Clause 20.1.9).
ComplexAck: ComplexACK PDU (Clause 20.1.5).

MINIMUM_MESSAGE_SIZE: MinimumMessageSize: the smallest APDU any BACnet device accepts.

advertised_max_segments: The segment count a configured max-segments-accepted actually promises a peer.
decode_apdu: Decode an APDU from raw bytes.
encode_apdu: Encode an APDU to wire format.
is_valid_max_apdu_length: Return true when value is one of the BACnet max-APDU-length encodings defined by ASHRAE 135-2020 Clause 20.1.2.5.
validate_max_apdu_length: Validate a locally configured max-APDU-length value.
validate_max_segments: Validate a configured maximum segment count for a Confirmed-Request header.
