pub const PROTO_VER: u8 = 9;Expand description
Control-protocol version in RESP(VERSION) (§4.1). The handshake refuses a box reporting any
other with Error::BadProtoVer; update that box from
https://medius.k4tech.net/dashboard.
9 (v3.4.2): RESP(STATS) grows from 17 to 31 bytes (a dropped-frame counter per inter-chip link
direction, one for relay back-pressure, and the session counter); a CONTROL event’s handshake
moves to flags bits 0-1, beside the rule bit (b7). 8 (v3.4.1): reshaped RESP(CLIP) and
CLIP_TRIGGER; an interrupt OUT packet on a vendor interface matches as VendorInterrupt (7
matched it as HidOut). 7 (v3.4.0): the advanced control layer (RAW/TRANSFER/REWRITE/
PATCH) and u16 HEALTH flags.
