## 🔍 What is MeshCore?

MeshCore now supports a range of LoRa devices, allowing for easy flashing without the need to compile firmware manually. Users can flash a pre-built binary using tools like Adafruit ESPTool and interact with the network through a serial console.
MeshCore provides the ability to create wireless mesh networks, similar to Meshtastic and Reticulum but with a focus on lightweight multi-hop packet routing for embedded projects. Unlike Meshtastic, which is tailored for casual LoRa communication, or Reticulum, which offers advanced networking, MeshCore balances simplicity with scalability, making it ideal for custom embedded solutions., where devices (nodes) can communicate over long distances by relaying messages through intermediate nodes. This is especially useful in off-grid, emergency, or tactical situations where traditional communication infrastructure is unavailable.

Please submit PR's using 'dev' as the base branch!
For minor changes just submit your PR and we'll try to review it, but for anything more 'impactful' please open an Issue first and start a discussion. Is better to sound out what it is you want to achieve first, and try to come to a consensus on what the best approach is, especially when it impacts the structure or architecture of this codebase.

Here are some general principals you should try to adhere to:
Here are some general principles you should try to adhere to:
* Keep it simple. Please, don't think like a high-level lang programmer. Think embedded, and keep code concise, without any unnecessary layers.
* No dynamic memory allocation, except during setup/begin functions.
* Use the same brace and indenting style that's in the core source modules. (A .clang-format is prob going to be added soon, but please do NOT retroactively re-format existing code. This just creates unnecessary diffs that make finding problems harder)

Help us prioritize! Please react with thumbs-up to issues/PRs you care about most. We look at reaction counts when planning work.

**Note:** When it is enabled, repeaters will now reject flood packets which look like they are in a loop. This has been happening recently in some meshes when there is just a single 'bad' repeater firmware out there (prob some forked or custom firmware). If the payload is messed with, then forwarded, the same packet ends up causing a packet storm, repeated up to the max 64 hops. This feature was added in firmware 1.14

**Example:** If preference is `loop.detect minimal`, and a 1-byte path size packet is received, the repeater will see if its own ID/hash is already in the path. If it's already encoded 4 times, it will reject the packet. If the packet uses 2-byte path size, and repeater's own ID/hash is already encoded 2 times, it rejects. If the packet uses 3-byte path size, and the repeater's own ID/hash is already encoded 1 time, it rejects.

`data_type` is an **application identifier**, not a payload-format identifier. Each registered value identifies an application that owns its own internal payload schemas. The firmware does not inspect payload contents — `data_type` is transported opaquely.

**Path Length semantics differ between send and receive**:

| Direction | `path_len = 0xFF` | `path_len ≠ 0xFF` |
|-----------|---------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------|
| Send | Flood the network | Direct route; the encoded path follows (low 6 bits = hash count, top 2 bits + 1 = hash size; on-wire byte count = `hash_count × hash_size`) |
| Receive | Packet arrived via direct route | Packet was flooded; this is the encoded `pkt->path_len` field as observed (no path bytes follow) |
| Receive | Packet arrived via direct route | Packet was flooded; this is the encoded `pkt->path_len` field as observed (no path bytes follow) |

In other words, the meaning of `0xFF` is inverted between the two directions, and on receive the field carries metadata only — never a routable path. `path_len` is an encoded byte (see `Packet::isValidPathLen` / `Packet::writePath` in `src/Packet.cpp`), not a raw byte count.
