- vendor orlp/ed25519 (lib/ed25519, MIT — the exact lib MeshCore uses) for Curve25519 ECDH key exchange; switch identity/advert signing to it (same seed -> same pubkey, so peers still recognise us; sigs are byte-identical) - store pubkeys from heard MeshCore adverts (contacts table) so a DM's 1-byte src_hash can be resolved to a full sender key - decode PAYLOAD_TYPE_TXT_MSG: ECDH shared secret, HMAC-SHA256 MAC check, AES-128-ECB decrypt, parse timestamp+text, drive the message modal - verified end-to-end: real MeshCore node -> "hello from HP Pro Desk" decoded Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
archy-messh
Research + firmware project exploring a single LoRa device that can speak, relay, and repeat between three independent mesh networking protocols:
- Meshtastic
- MeshCore
- Reticulum (via RNode-style modem firmware)
Goal: one ESP32-based device that acts as a tri-protocol repeater/bridge —
not a fork of any single project, and not affiliated with or dependent on
the archy (Archipelago) codebase. This repo is intentionally standalone.
Status
Architecture phase done — see docs/ARCHITECTURE.md for the protocol
research, hardware constraints (target: Heltec WiFi LoRa 32 V3), and
phased plan. Phase 0 (host-side bridge across 3 separate stock-firmware
boards) is written — see host-bridge/ — but not yet hardware-tested; no
LoRa boards have been attached to the dev machine this was written on.

Non-goals (for now)
- Not reimplementing any of the three protocols from scratch in v1
- Not targeting non-ESP32 hardware initially
- Not touching/depending on the
archy(Archipelago) repo in any way
