 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 unecessary layers.
+* 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)

+Bluefruit BLE Patch Script
+
+Patches Bluefruit library to fix semaphore leak bug that causes device lockup
+when BLE central disconnects unexpectedly (e.g., going out of range, supervision timeout).
+
+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

+# Stats Binary Frame Structures
+
+Binary frame structures for companion radio stats commands. All multi-byte integers use little-endian byte order.
+
+## Command Codes
+
+| Command | Code | Description |
+|---------|------|-------------|
+| `CMD_GET_STATS` | 56 | Get statistics (2-byte command: code + sub-type) |
+
+### Stats Sub-Types
+
+The `CMD_GET_STATS` command uses a 2-byte frame structure:
+- **Byte 0:** `CMD_GET_STATS` (56)
+- **Byte 1:** Stats sub-type:
+  - `STATS_TYPE_CORE` (0) - Get core device statistics
+  - `STATS_TYPE_RADIO` (1) - Get radio statistics
+  - `STATS_TYPE_PACKETS` (2) - Get packet statistics
+
+## Response Codes
+
+| Response | Code | Description |
+|----------|------|-------------|
+| `RESP_CODE_STATS` | 24 | Statistics response (2-byte response: code + sub-type) |
+
+### Stats Response Sub-Types
+
+The `RESP_CODE_STATS` response uses a 2-byte header structure:
+- **Byte 0:** `RESP_CODE_STATS` (24)
+- **Byte 1:** Stats sub-type (matches command sub-type):
+  - `STATS_TYPE_CORE` (0) - Core device statistics response
+  - `STATS_TYPE_RADIO` (1) - Radio statistics response
+  - `STATS_TYPE_PACKETS` (2) - Packet statistics response
+
+---
+
+## RESP_CODE_STATS + STATS_TYPE_CORE (24, 0)
+
+**Total Frame Size:** 11 bytes
+
+| Offset | Size | Type | Field Name | Description | Range/Notes |
+|--------|------|------|------------|-------------|-------------|
+| 0 | 1 | uint8_t | response_code | Always `0x18` (24) | - |
+| 1 | 1 | uint8_t | stats_type | Always `0x00` (STATS_TYPE_CORE) | - |
+| 2 | 2 | uint16_t | battery_mv | Battery voltage in millivolts | 0 - 65,535 |
+| 4 | 4 | uint32_t | uptime_secs | Device uptime in seconds | 0 - 4,294,967,295 |
+| 8 | 2 | uint16_t | errors | Error flags bitmask | - |
+| 10 | 1 | uint8_t | queue_len | Outbound packet queue length | 0 - 255 |
+
+### Example Structure (C/C++)
+
+```c
+struct StatsCore {
+    uint8_t  response_code;  // 0x18

+## Field Size Considerations
+
+- Packet counters (uint32_t): May wrap after extended high-traffic operation.
+- Time fields (uint32_t): Max ~136 years.
+- SNR (int8_t, scaled by 4): Range -32 to +31.75 dB, 0.25 dB precision.
