GAP
GAP is an acronym for the Generic Access Profile, and it controls connections and advertising in Bluetooth. GAP is what makes your device visible to the outside world, and determines how two devices can (or can't) interact with each other.
Device Roles
GAP defines various roles for devices, but the two key concepts to keep in mind are Central devices and Peripheral devices.
- Peripheral devices are small, low power, resource contrained devices that can connect to a much more powerful central device. Peripheral devices are things like a heart rate monitor, a BLE enabled proximity tag, etc.
- Central devices are usually the mobile phone or tablet that you connect to with far more processing power and memory.
