# 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.
|
|
|
|

|
|

|
|

|
|
