For more context: The BLE peripheral in my setup is a custom ESP32 chip that we’ve programmed to advertise both peripheral data and iBeacon data. This chip will be integrated into smart lock systems (for buildings, garages, etc.), with the goal of automatically unlocking the door when a resident comes close. The idea is that the app runs in the background and, once it detects the beacon (via region monitoring) and gets awakened, it initiates a connection with the peripheral to exchange security keys. If the residential criterion is met, the ESP32 then unlocks the door.
