class cbus.protocol.base_packet.SpecialClientPacket

Bases: cbus.protocol.base_packet._SpecialPacket, abc.ABC

Client -> PCI communications have some special packets, which we make subclasses of SpecialClientPacket to make them entirely separate from normal packets.

These have non-standard methods for serialisation.

class cbus.protocol.base_packet.SpecialServerPacket

Bases: cbus.protocol.base_packet._SpecialPacket, abc.ABC

PCI -> Client has some special packets that we make subclasses of this, because they’re different to regular packets.

These have non-standard serialisation methods.
