nRF52832 Circular Geofence Alarm

I already have a prototype built around the Nordic nRF52832 and now need firmware that keeps the device inside a user-defined circular zone. The position data is available, so your focus is the geofencing logic, alarm handling, and peer-to-peer communication. Here is what I need: • Continuous comparison of the current coordinates against a single circular fence whose centre and radius can be updated over BLE. • Immediate activation of an on-board buzzer whenever the fence is breached, with automatic silence once the device re-enters the zone. • A BLE broadcast (advertising or GATT, your choice) that lets neighbouring nRF52 devices know the fence was crossed so they can react too. If you have prior experience with Nordic chips, SoftDevice S132, or low-power BLE beacons, then share your experience and work i will be very glad to carry work with you .
