## 🔍 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.

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.

* 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)

# Security Policy
## Supported Versions
Security fixes are applied to the latest release only. We do not backport
fixes to older versions.
| Version | Supported |
|---------|-----------|
| 1.15+ | ✅ |
| <1.15 | |
## Reporting a Vulnerability
**Please do not report security vulnerabilities through public GitHub issues.**
Use GitHub's private vulnerability reporting instead:
1. Go to the **Security** tab of this repository
2. Click **Report a vulnerability**
3. Fill in the details and submit
### What to include
A useful report tells us:
- Which component or file is affected
- What an attacker can do (impact) and under what conditions
- A minimal reproduction case or proof-of-concept if you have one
- Whether you believe it is remotely exploitable
You do not need a working exploit to report. An incomplete report is better
than no report.
## What to expect
This is a volunteer-maintained open-source project. We will do our best to
respond in a reasonable timeframe, but cannot commit to specific deadlines.
We ask that you give us a fair opportunity to investigate and address the
issue before any public disclosure. If you have not heard back after
**90 days**, feel free to follow up or proceed with disclosure at your
discretion.
## Scope
In scope:
- Remote code execution, memory corruption, or denial-of-service via crafted
radio packets
- Authentication or encryption bypasses
- Vulnerabilities in the packet routing or path handling logic
Out of scope:
- Physical access attacks (e.g., JTAG, UART extraction of keys)
- Regulatory compliance (duty cycle, frequency restrictions)
- Jamming or other physical-layer radio interference
- Issues in third-party libraries (RadioLib, Crypto, etc.) — report those
upstream
- "Best practice" suggestions without a demonstrated attack path

Bluefruit BLE Patch Script
Patches Bluefruit library to fix semaphore leak bug that causes device lockup

Patches applied:
1. BLEConnection.h: Add _hvn_qsize member to track semaphore queue size
2. BLEConnection.cpp: Store hvn_qsize and restore semaphore on disconnect
Bug description:
- When a BLE central disconnects unexpectedly (reason=8 supervision timeout),
the BLE_GATTS_EVT_HVN_TX_COMPLETE event may never fire
- This leaves the _hvn_sem counting semaphore in a decremented state
- Since BLEConnection objects are reused (destructor never called), the
semaphore count is never restored
- Eventually all semaphore counts are exhausted and notify() blocks/fails

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.

**Note:** When multiple nearby repeaters all hear the same flood packet, each waits a random amount of time before retransmitting to avoid simultaneous collisions.

This gives strong-signal paths forwarding priority. By the time weak-signal nodes process their copy, the packet may have already propagated and will be suppressed as a duplicate, reducing redundant retransmissions.

#### Define region hierarchy (single line)
**Usage:**
- `region def <token> [<token> ...]`
**Parameters (tokens):** Space-separated. A logical **cursor** starts at the wildcard `*`.
- **`name`** — Create `name` as a child of the current cursor (equivalent to `region put name` with the cursor as parent). Cursor moves to `name`.
- **`name|jump`** *(or `name,jump`)* — Create `name` as a child of the current cursor, then move the cursor to `jump` (must already exist on the node, or have been created earlier in this command). `jump` is **not** the parent of `name`; use this form to pop back up and start another branch.
**Behavior:** Each created region defaults to flood-allowed (same as `region put`). The reply is the resulting region tree (same format as bare `region`); review it before running `region save` to persist. On error, the reply is `Err - ...` and any regions placed before the failure remain on the node, just like a partial chain of `region put`.
**Existing regions:** `region def` does not clear the existing tree — if a name already exists, its parent is updated to the current cursor; otherwise a new region is created. To start from scratch, `region remove` the unwanted regions first.
**Limits:** Repeater serial accepts one line up to **160 characters**. For larger trees, split across multiple `region def` commands; the cursor resets to `*` between commands, so lead the next command with `child|ancestor` to reposition. Each token splits at most once on `|``region def a|b|c|d` is not a flat-list shorthand; see the flat-list example below.
**Example — linear chain** (each token becomes a child of the previous):
```
region def a b c d e
region save
```
**Example — branched tree** (equivalent to `region put a`, `region put b a`, `region put c b`, `region put d c`, `region put e b`, `region put f e`):
```
region def a b c d|b e f
region save
```
**Example — error and partial state:**
```
region def a b c|nope d
```
The reply is `Err - unknown jump: nope`. `a`, `b`, and `c` were placed before the failure; `d` was not. Run `region` to inspect, then re-run with a corrected jump or repair with `region remove` / `region put`.
**Example — flat list** (each region a child of `*`). Use `|*` after each token to pop the cursor back to the root before the next token:
```
region def a|* b|* c|* d|* e|* f
region save
```

### 6. Get Message
### 6. Send Channel Data Datagram
**Purpose**: Send a binary datagram to a channel. Unlike channel text messages, datagrams carry no built-in sender identity and no timestamp — applications needing either must encode them inside the binary payload.
**Command Format**:
```
Byte 0: 0x3E
Byte 1: Channel Index (0-7)
Byte 2: Path Length (0xFF = flood, otherwise actual path length)
Bytes 3 .. 2+path_len: Path (omitted when path_len == 0xFF)
Next 2 bytes (little-endian): Data Type (`data_type`, uint16)
Remaining bytes: Binary payload (variable length)
```
**Example** (flood, `DATA_TYPE_DEV`, payload `A1 B2 C3`, channel 1):
```
3E 01 FF FF FF A1 B2 C3
```
**Data Type / Transport Mapping**:
- `0x0000` (`DATA_TYPE_RESERVED`) is invalid and rejected with `PACKET_ERROR`.
- `0xFFFF` (`DATA_TYPE_DEV`) is the developer namespace for experimenting and developing apps.
- Values `0x0001`–`0xFFFE` are available for registered application/community namespaces. See the [Registered data_type values](#registered-data_type-values) table below.
**Limits**:
- Maximum payload length is `MAX_CHANNEL_DATA_LENGTH = MAX_FRAME_SIZE - 9 = 163` bytes.
- Larger payloads are rejected with `PACKET_ERROR` (`ERR_CODE_ILLEGAL_ARG`).
**Response**: `PACKET_OK` (0x00) on success, or `PACKET_ERROR` (0x01) with one of:
- `ERR_CODE_NOT_FOUND` (2) — unknown `channel_idx`
- `ERR_CODE_ILLEGAL_ARG` (6) — invalid `path_len`, reserved `data_type` (`0x0000`), or payload larger than `MAX_CHANNEL_DATA_LENGTH`
- `ERR_CODE_TABLE_FULL` (3) — outbound send queue is full; retry later
**Inbound datagrams** are delivered to the host via `RESP_CODE_CHANNEL_DATA_RECV` (0x1B); see [Receive Channel Data Datagram](#receive-channel-data-datagram).
#### Registered `data_type` values
`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.
| Value | Constant | Purpose |
|-----------------|----------------------|----------------------------------------------------------------------------------------|
| 0x0000 | `DATA_TYPE_RESERVED` | Reserved; invalid on send |
| 0x0001 – 0x00FF | — | Reserved for internal use |
| 0x0100 – 0xFEFF | — | Registered application namespaces (see [number_allocations.md](number_allocations.md)) |
| 0xFF00 – 0xFFFE | — | Testing/development; no registration required |
| 0xFFFF | `DATA_TYPE_DEV` | Developer/experimental namespace |
To register a new application, submit a PR adding a row to the table in [docs/number_allocations.md](number_allocations.md). Internal sub-formats within an allocated application ID are owned by that application and are not tracked in MeshCore firmware or this document.

### Receive Channel Data Datagram
Inbound group datagrams (radio-level `PAYLOAD_TYPE_GRP_DATA`, 0x06) are forwarded to the host as `RESP_CODE_CHANNEL_DATA_RECV` notifications.
**Frame Format** (`RESP_CODE_CHANNEL_DATA_RECV`, 0x1B):
```
Byte 0: 0x1B (packet type)
Byte 1: SNR (signed int8, scaled ×4 — divide by 4.0 to recover dB)
Bytes 2-3: Reserved (clients MUST ignore)
Byte 4: Channel Index (0-7)
Byte 5: Path Length (actual path length when flooded, otherwise 0xFF for direct)
Bytes 6-7: Data Type (uint16 little-endian)
Byte 8: Data Length
Bytes 9 .. 8+data_len: Payload
```
**Path bytes are not forwarded**: Only `path_len` is reported in the receive frame — the path itself is not copied to the host. There are no path bytes between byte 5 and the data_type field at bytes 6–7, regardless of `path_len`.
**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) |
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.
**Note**: The device may also emit `PACKET_MESSAGES_WAITING` (0x83) to notify the host that datagrams are queued; poll with `CMD_SYNC_NEXT_MESSAGE` (0x0A) to retrieve them.
**Parsing Pseudocode**:
```python
def parse_channel_data_recv(data):
if len(data) < 9:
return None
snr_byte = data[1]
snr = (snr_byte if snr_byte < 128 else snr_byte - 256) / 4.0
channel_idx = data[4]
path_len = data[5]
data_type = int.from_bytes(data[6:8], 'little')
data_len = data[8]
if 9 + data_len > len(data):
return None
payload = data[9:9 + data_len]
return {
'snr': snr,
'channel_idx': channel_idx,
'path_len': path_len,
'data_type': data_type,

### Terminology
This document uses a spec-level naming convention (`PACKET_*`) for bytes the firmware sends back to the host. In the firmware source these same values are split across two `#define` families by purpose:
- `RESP_CODE_*` — direct replies to a command (e.g. `RESP_CODE_CHANNEL_DATA_RECV` = `PACKET_CHANNEL_DATA_RECV` = 0x1B).
- `PUSH_CODE_*` — asynchronous notifications not tied to a specific command (e.g. `PUSH_CODE_MSG_WAITING` = `PACKET_MESSAGES_WAITING` = 0x83).
Byte values are authoritative; names are aliases. When reading firmware source, `RESP_CODE_X` / `PUSH_CODE_X` correspond to this doc's `PACKET_X` of the same numeric value.

# Number Allocations
This document lists unique numbers/identifiers used in various MeshCore protocol payloads.
# Group Data Types
The `PAYLOAD_TYPE_GRP_DATA` payloads have a 16-bit data-type field, which identifies which application the packet is for.
To make sure multiple applications can function without interfering with each other, the table below is for reserving various ranges of data-type values. Just modify this table, adding a row, then submit a PR to have it authorised/merged.
NOTE: the range FF00 - FFFF is for use while you're developing, doing POC, and for these you don't need to request to use/allocate.
Once you have a working app/project, you need to be able to demonstrate it exists/works, and THEN request type IDs. So, just use the testing/dev range while developing, then request IDs before you transition to publishing your project.
