Introduction

The Blaeck protocol is a lightweight binary protocol for streaming typed signal data from embedded devices to host applications. It supports device discovery, schema negotiation, timestamped data frames, and integrity checking — all within a compact, deterministic wire format.

Protocol at a Glance

Every Blaeck message is wrapped in a fixed envelope:

<BLAECK: MSGKEY(1B) : MSGID(4B) : FRAME /BLAECK>\r\n

• Message Key identifies the frame (e.g., 0xD2 for data with 8-byte timestamps).
• Message ID is a user-defined uint32.
• Frame carries the key-specific payload.

All multi-byte integers throughout the protocol are little-endian.

See Frames for all frame definitions.
