...service that hardens my phones and tablets by tying their safety to a Samsung Watch. Core workflow • While the watch is paired and within 50 m (GPS), the device behaves normally. • If the watch travels beyond that radius, a countdown starts (length to be parameterised in settings). When the timer expires, the handset performs a full factory reset. • The same timer-then-reset sequence is triggered whenever the watch is powered off or its Bluetooth connection is deliberately severed. • A unique, user-set PIN must be entered on the system lock screen to cancel the reset once it has begun.

I have a custom board built around the STM32G031 and I want a clean, production-ready firmware project created in C with STM32CubeIDE. Your first task is to bring the microcontroller to life: set up the system clock, configure the required GPIO pins, verify the build, and program the device. Here is the scope I need covered: • Create a CubeIDE project that targets STM32G031, using either HAL or direct LL drivers where it makes sense. • Configure clock tree (HSE, HSI or internal PLL as required) so the MCU runs at the specified operating frequency. • Initialise all GPIOs I mark on the schematic; direction, speed and pull settings must match the hardware design. • Build, generate the .hex/.bin files and flash them onto the board through ST-Link over SWD. ...
