What is BLE iOS?
One of the main features of the Bluetooth 4 specification is Bluetooth Low Energy (BLE). Also called Bluetooth smart, this technology allows peripherals to communicate by consuming much less energy than regular Bluetooth.
What is core Bluetooth?
Core Bluetooth is an API for “Bluetooth Low Energy” (BLE), also known as “Bluetooth 4.0.” BLE uses much less power because it’s designed to communicate small amounts of data. A great example of a BLE device is a heart rate monitor (HRM). It sends just a few bytes of data approximately every second.
What is BLE in Swift?
In case you’re not yet familiar with Bluetooth Low Energy (BLE), here’s a quick(bird)™️ overview of the main components. 😉 (Otherwise, just skip this section.) A BLE peripheral typically offers several services. Each service represents a particular functionality. It groups related data and behaviors.
Does iPhone use Bluetooth Low Energy?
There are two types of Bluetooth in Apple devices, Bluetooth Classic and Bluetooth Low Energy (BLE)….Bluetooth security.
| Support | Bluetooth Classic | Bluetooth Low Energy |
|---|---|---|
| Bluetooth 4.2 or later | iPhone 6 or later | iOS 9 or later iPadOS 13.1 or later macOS 10.12 or later tvOS 9 or later watchOS 2.0 or later |
What is CBCharacteristic?
CBCharacteristic and its subclass CBMutableCharacteristic represent further information about a peripheral’s service. In particular, CBCharacteristic objects represent the characteristics of a remote peripheral’s service. A characteristic contains a single value and any number of descriptors describing that value.
What is kCBAdvDataManufacturerData?

What is CBPeripheral?
The CBPeripheral class represents remote peripheral devices that your app discovers with a central manager (an instance of CBCentralManager ). You use this class to discover, explore, and interact with the services available on a remote peripheral that supports Bluetooth low energy.
What is GATT Bluetooth?
GATT is an acronym for the Generic Attribute Profile, and it defines the way that two Bluetooth Low Energy devices transfer data back and forth using concepts called Services and Characteristics. What is meant by that is that a BLE peripheral can only be connected to one central device (a mobile phone, etc.)
Can iPhone Bluetooth be hacked?
Bluetooth hacks can take place when a hacker uses their own Bluetooth connection to gain access to your phone. However, this can only happen if your phone is within the Bluetooth range of a potential hacker. Usually, this range is around 30 feet.
