class Matter::Protocol::MessageHandler

• Matter::Protocol::MessageHandler
• Reference
• Object

Overview

Protocol message handler that routes incoming messages to appropriate handlers

Handles:

• Secure Channel protocol (0x0000) - PASE, CASE, etc.
• Interaction Model protocol (0x0001) - Read, Write, Invoke, Subscribe

Defined in:

matter/protocol/message_handler.cr
