-# Contributing to MeshCore
-
-Thanks for considering contributing to this project!  
-
-## How Can I Contribute?
-
-### 1. Reporting Bugs
- Use the **Issues** tracker
- Use a clear title (e.g. "Crash when calling begin() with invalid pin")
- Describe the **exact steps** to reproduce
- Include your **board**, **IDE version**, **library version** and **relevant code snippet**
- Attach minimal complete example sketch if possible
-
-### 2. Suggesting Enhancements / New Features
- Open an issue with the prefix **[Feature request]**
- Explain the use-case → what problem would this solve?
- Describe your ideal API / behavior (code examples are very helpful)
-
-### 3. Submitting Code Changes (Pull Requests)
-
-#### Small fixes (typos, comments, examples, small bug fixes)
-→ Just open a pull request — no prior issue needed
-
-#### Larger changes / new features
-1. Open an issue first to discuss the idea
-2. Get a rough 👍 from maintainer(s)
-3. Fork the repo from 'dev' branch and create your branch (`fix/xxx`, `feature/yyy`, `docs/whatever`)
-4. Make your changes
-5. Update or add examples when appropriate
-6. Add/update comments in code
-7. Submit the pull request
-
-### Pull Request Guidelines
-
- **One feature / fix = one pull request** (smaller PRs are easier & faster to review)
- Use descriptive commit messages
-  - Good: `Fix I2C timeout handling on ESP32`
-  - Bad: `update`
- Reference any related issue (`Fixes #123`, `Closes #89`, etc.)
- If you change public API, update README.md and library.properties
- New features should include an example sketch in `examples/`
-
-## Coding Style
-
-PLease follow the existing C++ style (per the .clang-format)
-
- 2 spaces indentation (no tabs)
- `camelCase` for functions and variables
- `UpperCamelCase` / `PascalCase` for class names
- `#define` constants in `ALL_CAPS`
- Keep lines < ~100 characters when reasonable
-
-(But consistency with existing code is more important than strict rules)
-
-## Thank You!

 ## Contributing

 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.
+For minor changes just submit your PR and I'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:
 * 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.

-**Usage:**

-
-**Parameters:**
- `value`: Path hash size (0-2)
-  - `0`: 1 Byte hash size (256 unique ids)[64 max flood]
-  - `1`: 2 Byte hash size (65,536 unique ids)[32 max flood]
-  - `2`: 3 Byte hash size (16,777,216 unique ids)[21 max flood]
-  - `3`: DO NOT USE (Reserved) 
-
-**Default:** `0`
-
-**Note:** the 'path.hash.mode' sets the low-level ID/hash encoding size used when the repeater adverts. This setting has no impact on what packet ID/hash size this repeater forwards, all sizes should be forwarded on firmware >= 1.14. This feature was added in firmware 1.14
-
-**Temporary Note:** adverts with ID/hash sizes of 2 or 3 bytes may have limited flood propogation in your network while this feature is new as v1.13.0 firmware and older will drop packets with multibyte path ID/hashes as only 1-byte hashes are suppored. Consider your install base of firmware >=1.14 has reached a criticality for effective network flooding before implementing higher ID/hash sizes.

-#### View or change this node's loop detection
-**Usage:**
- `get loop.detect`
- `set loop.detect <state>`
-
-**Parameters:**
- `state`: 
-  - `off`: no loop detection is performed
-  - `minimal`: packets are dropped if repeater's ID/hash appears 4 or more times (1-byte), 2 or more (2-byte), 1 or more (3-byte)
-  - `moderate`: packets are dropped if repeater's ID/hash appears 2 or more times (1-byte), 1 or more (2-byte), 1 or more (3-byte)
-  - `strict`: packets are dropped if repeater's ID/hash appears 1 or more times (1-byte), 1 or more (2-byte), 1 or more (3-byte)
-  
-**Default:** `off`
-
-**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.

-
 **Usage:**
 - `get af`
 - `set af <value>`

 **Parameters:**
- `value`: Airtime factor (0-9). After each transmission, the repeater enforces a silent period of approximately the on-air transmission time multiplied by the value. This results in a long-term duty cycle of roughly 1 divided by (1 plus the value). For example:
-  - `af = 1` → ~50% duty
-  - `af = 2` → ~33% duty
-  - `af = 3` → ~25% duty
-  - `af = 9` → ~10% duty
-  You are responsible for choosing a value that is appropriate for your jurisdiction and channel plan (for example EU 868 Mhz 10% duty cycle regulation).

-### Frame Handling
+### Partial Packet Handling

-BLE implementations enqueue and deliver one protocol frame per BLE write/notification at the firmware layer.
+BLE notifications may arrive in chunks, especially for larger packets. Implement buffering:

- Apps should treat each characteristic write/notification as exactly one companion protocol frame
- Apps should still validate frame lengths before parsing
- Future transports or firmware revisions may differ, so avoid assuming fixed payload sizes for variable-length responses
+**Implementation**:
+```python
+class PacketBuffer:
+    def __init__(self):
+        self.buffer = bytearray()
+        self.expected_length = None
+    
+    def add_data(self, data):

 ### Response Handling

 1. **Command-Response Pattern**:
-   - Send command via RX characteristic
-   - Wait for response via TX characteristic (notification)
+   - Send command via TX characteristic
+   - Wait for response via RX characteristic (notification)
   - Match response to command using sequence numbers or command type
   - Handle timeout (typically 5 seconds)
   - Use command queue to prevent concurrent commands

 2. **Asynchronous Messages**:
-   - Device may send messages at any time via TX characteristic
+   - Device may send messages at any time via RX characteristic
   - Handle `PACKET_MESSAGES_WAITING` (0x83) by polling `GET_MESSAGE` command
   - Parse incoming messages and route to appropriate handlers
-   - Validate frame length before decoding
+   - Buffer partial packets until complete

 3. **Response Matching**:
   - Match responses to commands by expected packet type:
-     - `APP_START` → `PACKET_SELF_INFO`
+     - `APP_START` → `PACKET_OK`
     - `DEVICE_QUERY` → `PACKET_DEVICE_INFO`
     - `GET_CHANNEL` → `PACKET_CHANNEL_INFO`
     - `SET_CHANNEL` → `PACKET_OK` or `PACKET_ERROR`

-# MeshCore KISS Modem Protocol
-
-Standard KISS TNC firmware for MeshCore LoRa radios. Compatible with any KISS client (Direwolf, APRSdroid, YAAC, etc.) for sending and receiving raw packets. MeshCore-specific extensions (cryptography, radio configuration, telemetry) are available through the standard SetHardware (0x06) command.
-
-## Serial Configuration
-
-115200 baud, 8N1, no flow control.
-
-## Frame Format
-
-Standard KISS framing per the KA9Q/K3MC specification.
-
-| Byte | Name | Description |
-|------|------|-------------|
-| `0xC0` | FEND | Frame delimiter |
-| `0xDB` | FESC | Escape character |
-| `0xDC` | TFEND | Escaped FEND (FESC + TFEND = 0xC0) |
-| `0xDD` | TFESC | Escaped FESC (FESC + TFESC = 0xDB) |
-
-```
-┌──────┬───────────┬──────────────┬──────┐
-│ FEND │ Type Byte │ Data (escaped)│ FEND │
-│ 0xC0 │  1 byte   │ 0-510 bytes  │ 0xC0 │
-└──────┴───────────┴──────────────┴──────┘
-```
-
-### Type Byte
-
-The type byte is split into two nibbles:
-
-| Bits | Field | Description |
-|------|-------|-------------|
-| 7-4 | Port | Port number (0 for single-port TNC) |
-| 3-0 | Command | Command number |
-
-Maximum unescaped frame size: 512 bytes.
-
-## Standard KISS Commands
-
-### Host to TNC
-
-| Command | Value | Data | Description |
-|---------|-------|------|-------------|
-| Data | `0x00` | Raw packet | Queue packet for transmission |
-| TXDELAY | `0x01` | Delay (1 byte) | Transmitter keyup delay in 10ms units (default: 50 = 500ms) |
-| Persistence | `0x02` | P (1 byte) | CSMA persistence parameter 0-255 (default: 63) |
-| SlotTime | `0x03` | Interval (1 byte) | CSMA slot interval in 10ms units (default: 10 = 100ms) |
-| TXtail | `0x04` | Delay (1 byte) | Post-TX hold time in 10ms units (default: 0) |
-| FullDuplex | `0x05` | Mode (1 byte) | 0 = half duplex, nonzero = full duplex (default: 0) |
-| SetHardware | `0x06` | Sub-command + data | MeshCore extensions (see below) |
-| Return | `0xFF` | - | Exit KISS mode (no-op) |
-
-### TNC to Host
-
-| Type | Value | Data | Description |
-|------|-------|------|-------------|
-| Data | `0x00` | Raw packet | Received packet from radio |
-
-Data frames carry raw packet data only, with no metadata prepended. The Data command payload is limited to 255 bytes to match the MeshCore maximum transmission unit (MAX_TRANS_UNIT); frames larger than 255 bytes are silently dropped. The KISS specification recommends at least 1024 bytes for general-purpose TNCs; this modem is intended for MeshCore packets only, whose protocol MTU is 255 bytes.
-
-### CSMA Behavior
-
-The TNC implements p-persistent CSMA for half-duplex operation:
-
-1. When a packet is queued, monitor carrier detect
-2. When the channel clears, generate a random value 0-255
-3. If the value is less than or equal to P (Persistence), wait TXDELAY then transmit
-4. Otherwise, wait SlotTime and repeat from step 1
-
-In full-duplex mode, CSMA is bypassed and packets transmit after TXDELAY.
-
-## SetHardware Extensions (0x06)
-
-MeshCore-specific functionality uses the standard KISS SetHardware command. The first byte of SetHardware data is a sub-command. Standard KISS clients ignore these frames.
-
-### Frame Format
-
-```
-┌──────┬──────┬─────────────┬──────────────┬──────┐
-│ FEND │ 0x06 │ Sub-command  │ Data (escaped)│ FEND │

-
-### Unsolicited Events
-
-The TNC sends these SetHardware frames without a preceding request:
-
-**TxDone (0xF8)**: Sent after a packet has been transmitted. Contains a single byte: 0x01 for success, 0x00 for failure.
-
-**RxMeta (0xF9)**: Sent immediately after each standard data frame (type 0x00) with metadata for the received packet. Contains SNR (1 byte, signed, value x4 for 0.25 dB precision) followed by RSSI (1 byte, signed, dBm). Enabled by default; can be toggled with SetSignalReport. Standard KISS clients ignore this frame.

-## Notes
-
- Data payload limit (255 bytes) matches MeshCore MAX_TRANS_UNIT; no change needed for KISS “1024+ recommended” (that applies to general TNCs, not MeshCore)
- Modem generates identity on first boot (stored in flash)
- All multi-byte values are little-endian unless stated otherwise
- SNR values in RxMeta are multiplied by 4 for 0.25 dB precision
- TxDone is sent as a SetHardware event after each transmission
- Standard KISS clients receive only type 0x00 data frames and can safely ignore all SetHardware (0x06) frames

-| 6-7  | Hash Size Code | Stored as `hash_size - 1` |
-
-Hash size codes:
-
-| Bits 6-7 | Hash Size | Notes |
-|----------|-----------|-------|
-| `0b00` | 1 byte | Legacy / default mode |
-| `0b01` | 2 bytes | Supported in current firmware |
-| `0b10` | 3 bytes | Supported in current firmware |
-| `0b11` | 4 bytes | Reserved / invalid |
-
-Examples:
