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

# nRF52 Power Management
## Overview
The nRF52 Power Management module provides battery protection features to prevent over-discharge, minimise likelihood of brownout and flash corruption conditions existing, and enable safe voltage-based recovery.
## Features
### Boot Voltage Protection
- Checks battery voltage immediately after boot and before mesh operations commence
- If voltage is below a configurable threshold (e.g., 3300mV), the device configures voltage wake (LPCOMP + VBUS) and enters protective shutdown (SYSTEMOFF)
- Prevents boot loops when battery is critically low
- Skipped when external power (USB VBUS) is detected
### Voltage Wake (LPCOMP + VBUS)
- Configures the nRF52's Low Power Comparator (LPCOMP) before entering SYSTEMOFF
- Enables USB VBUS detection so external power can wake the device
- Device automatically wakes when battery voltage rises above recovery threshold or when VBUS is detected
### Early Boot Register Capture
- Captures RESETREAS (reset reason) and GPREGRET2 (shutdown reason) before SystemInit() clears them
- Allows firmware to determine why it booted (cold boot, watchdog, LPCOMP wake, etc.)
- Allows firmware to determine why it last shut down (user request, low voltage, boot protection)
### Shutdown Reason Tracking
Shutdown reason codes (stored in GPREGRET2):
| Code | Name | Description |
|------|------|-------------|
| 0x00 | NONE | Normal boot / no previous shutdown |
| 0x4C | LOW_VOLTAGE | Runtime low voltage threshold reached |
| 0x55 | USER | User requested powerOff() |
| 0x42 | BOOT_PROTECT | Boot voltage protection triggered |
## Supported Boards

Notes:
- "Implemented" reflects Phase 1 (boot lockout + shutdown reason capture).
- User power-off on Heltec T114 does not enable LPCOMP wake.
- VBUS detection is used to skip boot lockout on external power, and VBUS wake is configured alongside LPCOMP when supported hardware exposes VBUS to the nRF52.
## Technical Details
### Architecture
The power management functionality is integrated into the `NRF52Board` base class in `src/helpers/NRF52Board.cpp`. Board variants provide hardware-specific configuration via a `PowerMgtConfig` struct and override `initiateShutdown(uint8_t reason)` to perform board-specific power-down work and conditionally enable voltage wake (LPCOMP + VBUS).
### Early Boot Capture
A static constructor with priority 101 in `NRF52Board.cpp` captures the RESETREAS and GPREGRET2 registers before:
- SystemInit() (priority 102) - which clears RESETREAS
- Static C++ constructors (default priority 65535)
This ensures we capture the true reset reason before any initialisation code runs.
### Board Implementation
To enable power management on a board variant:
1. **Enable in platformio.ini**:
```ini
-D NRF52_POWER_MANAGEMENT
```
2. **Define configuration in variant.h**:
```c
#define PWRMGT_VOLTAGE_BOOTLOCK 3300 // Won't boot below this voltage (mV)
#define PWRMGT_LPCOMP_AIN 7 // AIN channel for voltage sensing
#define PWRMGT_LPCOMP_REFSEL 2 // REFSEL (0-6=1/8..7/8, 7=ARef, 8-15=1/16..15/16)
```
3. **Implement in board .cpp file**:
```cpp
#ifdef NRF52_POWER_MANAGEMENT
const PowerMgtConfig power_config = {
.lpcomp_ain_channel = PWRMGT_LPCOMP_AIN,
.lpcomp_refsel = PWRMGT_LPCOMP_REFSEL,
.voltage_bootlock = PWRMGT_VOLTAGE_BOOTLOCK
};
void MyBoard::initiateShutdown(uint8_t reason) {
// Board-specific shutdown preparation (e.g., disable peripherals)
bool enable_lpcomp = (reason == SHUTDOWN_REASON_LOW_VOLTAGE ||
reason == SHUTDOWN_REASON_BOOT_PROTECT);
if (enable_lpcomp) {
configureVoltageWake(power_config.lpcomp_ain_channel, power_config.lpcomp_refsel);
}
enterSystemOff(reason);
}
#endif
void MyBoard::begin() {
NRF52Board::begin(); // or NRF52BoardDCDC::begin()
// ... board setup ...
#ifdef NRF52_POWER_MANAGEMENT
checkBootVoltage(&power_config);
#endif
}
```
For user-initiated shutdowns, `powerOff()` remains board-specific. Power management only arms LPCOMP for automated shutdown reasons (boot protection/low voltage).
4. **Declare override in board .h file**:
```cpp
#ifdef NRF52_POWER_MANAGEMENT
void initiateShutdown(uint8_t reason) override;
#endif
```
### Voltage Wake Configuration
The LPCOMP (Low Power Comparator) is configured to:
- Monitor the specified AIN channel (0-7 corresponding to P0.02-P0.05, P0.28-P0.31)
- Compare against VDD fraction reference (REFSEL: 0-6=1/8..7/8, 7=ARef, 8-15=1/16..15/16)
- Detect UP events (voltage rising above threshold)
- Use 50mV hysteresis for noise immunity
- Wake the device from SYSTEMOFF when triggered
VBUS wake is enabled via the POWER peripheral USBDETECTED event whenever `configureVoltageWake()` is used. This requires USB VBUS to be routed to the nRF52 (typical on nRF52840 boards with native USB).
**LPCOMP Reference Selection (PWRMGT_LPCOMP_REFSEL)**:
| REFSEL | Fraction | VBAT @ 1M/1M divider (VDD=3.0-3.3) | VBAT @ 1.5M/1M divider (VDD=3.0-3.3) |
|--------|----------|------------------------------------|--------------------------------------|
| 0 | 1/8 | 0.75-0.82 V | 0.94-1.03 V |
| 1 | 2/8 | 1.50-1.65 V | 1.88-2.06 V |
| 2 | 3/8 | 2.25-2.47 V | 2.81-3.09 V |
| 3 | 4/8 | 3.00-3.30 V | 3.75-4.12 V |
| 4 | 5/8 | 3.75-4.12 V | 4.69-5.16 V |
| 5 | 6/8 | 4.50-4.95 V | 5.62-6.19 V |
| 6 | 7/8 | 5.25-5.77 V | 6.56-7.22 V |
| 7 | ARef | - | - |
| 8 | 1/16 | 0.38-0.41 V | 0.47-0.52 V |
| 9 | 3/16 | 1.12-1.24 V | 1.41-1.55 V |
| 10 | 5/16 | 1.88-2.06 V | 2.34-2.58 V |
| 11 | 7/16 | 2.62-2.89 V | 3.28-3.61 V |
| 12 | 9/16 | 3.38-3.71 V | 4.22-4.64 V |
| 13 | 11/16 | 4.12-4.54 V | 5.16-5.67 V |
| 14 | 13/16 | 4.88-5.36 V | 6.09-6.70 V |
| 15 | 15/16 | 5.62-6.19 V | 7.03-7.73 V |
**Important**: For boards with a voltage divider on the battery sense pin, LPCOMP measures the divided voltage. Use:
`VBAT_threshold ≈ (VDD * fraction) * divider_scale`, where `divider_scale = (Rtop + Rbottom) / Rbottom` (e.g., 2.0 for 1M/1M, 2.5 for 1.5M/1M, 3.0 for XIAO).
### SoftDevice Compatibility
The power management code checks whether SoftDevice is enabled and uses the appropriate API:
- When SD enabled: `sd_power_*` functions
- When SD disabled: Direct register access (NRF_POWER->*)
This ensures compatibility regardless of BLE stack state.
## CLI Commands
Power management status can be queried via the CLI:
| Command | Description |
|---------|-------------|
| `get pwrmgt.support` | Returns "supported" or "unsupported" |
| `get pwrmgt.source` | Returns current power source - "battery" or "external" (5V/USB power) |
| `get pwrmgt.bootreason` | Returns reset and shutdown reason strings |
| `get pwrmgt.bootmv` | Returns boot voltage in millivolts |
On boards without power management enabled, all commands except `get pwrmgt.support` return:
```
ERROR: Power management not supported
```
## Debug Output
When `MESH_DEBUG=1` is enabled, the power management module outputs:
```
DEBUG: PWRMGT: Reset = Wake from LPCOMP (0x20000); Shutdown = Low Voltage (0x4C)
DEBUG: PWRMGT: Boot voltage = 3450 mV (threshold = 3300 mV)
DEBUG: PWRMGT: LPCOMP wake configured (AIN7, ref=3/8 VDD)
```
## Phase 2 (Planned)
- Runtime voltage monitoring
- Voltage state machine (Normal -> Warning -> Critical -> Shutdown)
- Configurable thresholds
- Load shedding callbacks for power reduction
- Deep sleep integration
- Scheduled wake-up
- Extended sleep with periodic monitoring
