Mesh gets contacts, channels, delivery receipts, QR sharing and an ESP-NOW radio. Mesh Chat is split into Mesh Contacts and Mesh Channels, `mesh inspect` replaces the Mesh Inspect app, and ESP-NOW and Wi-Fi now share the Wi-Fi radio safely.

# MeshCore backend
|
|
|
|
[MeshCore](https://github.com/meshcore-dev/MeshCore) protocol backend for the mesh service (`mesh-module`).
|
|
It registers itself with `mesh_backend_register()` as `meshcore`.
|
|
|
|
Supported:
|
|
|
|
- Identity: an Ed25519 key pair created on first start and stored in the backend's data directory.
|
|
- Adverts: sent at start and every 12 hours, received adverts are verified and remembered as contacts.
|
|
- Channel messages (`GRP_TXT`): the "Public" channel is preconfigured, more channels can be added with
|
|
`mesh_set_channel()` (16-byte keys).
|
|
- Direct messages (`TXT_MSG`) to and from known contacts, sent as flood packets. Received messages are
|
|
acknowledged, and acknowledgements of sent messages mark them as delivered.
|
|
|
|
This node is a chat node: it does not repeat packets for others.
|
|
|
|
Radio presets: "Default" is EU_868 (869.618 MHz, 62.5 kHz, SF8, CR 4/8) US_915 (910.525 MHz, 62.5 kHz, SF7, CR 4/5) or
|
|
AU_915 (915.8 MHz, 250 kHz, SF10, CR 4/5).
|
|
"EU NL" is the Dutch community setting for EU_868: 869.618 MHz, 62.5 kHz, SF7, CR 4/5.
|
|
Other regions report `ERROR_NOT_SUPPORTED`.
|
|
A radio with `RADIO_MODULATION_ESPNOW` (no LoRa) uses MeshCore's ESP-NOW transport in every region, without presets:
|
|
unencrypted broadcast frames on Wi-Fi channel 1 at 20 dBm. It reaches other Tactility and MeshCore ESP-NOW nodes in
|
|
Wi-Fi range, not LoRa nodes.
|
|
|
|
Not implemented: path learning (direct routing), requests to repeaters and room servers, multi-part messages.
