Introduction to Core Bluetooth: Building a Heart Rate Monitor. If you're new here, you may want to subscribe to my RSS feed or follow me on Twitter. Thanks for visiting! Learn how to use Core Bluetooth on a real-world device! The Core Bluetooth framework lets your iOS and Mac apps communicate with Bluetooth low energy devices (Bluetooth LE for short). Bluetooth LE devices include heart rate monitors, digital thermostats, and more. The Core Bluetooth framework is an abstraction of the Bluetooth 4.0 specification and defines a set of easy-to-use protocols for communicating with Bluetooth LE devices.
In this tutorial, you’ll learn about the key concepts of the Core Bluetooth framework and how to leverage the framework to discover, connect, and retrieve data from compatible devices. The heart rate monitor we use in this tutorial is the Polar H7 Bluetooth Smart Heart Rate Sensor. Allright, it’s Bluetooth LE time! Understanding Central and Peripheral Devices in Bluetooth A central is kinda like the “boss”. The following image illustrates this relationship: Characteristics | Bluetooth Development Portal. DIS | Bluetooth Development Portal. BTRichHTML2 The Device Information Service (DIS) exposes manufacturer information about a device. Conformance - If a device claims conformance to this service, all capabilities indicated as mandatory for this service shall be supported in the specified manner (process-mandatory).
This also applies for all optional and conditional capabilities for which support is indicated. All mandatory capabilities, and optional and conditional capabilities for which support is indicated, are subject to verification as part of the Bluetooth qualification program. Service Dependency - This service is not dependent upon any other services. Bluetooth Specification Release Compatibility - This service is compatible with any Bluetooth core specification host that includes the Generic Attribute Profile (GATT) and Bluetooth Low Energy Controller.
GATT Sub-Procedure Requirements - This service does not have any GATT Sub-Procedure requirements. Error Codes - This service does not define any application error codes.

Core Bluetooth Programming Guide: Core Bluetooth Background Processing for iOS Apps. For iOS apps, it is crucial to know whether your app is running in the foreground or the background. An app must behave differently in the background than in the foreground, because system resources are more limited on iOS devices. For an overall discussion of multitasking on iOS, see “App States and Multitasking” in iOS App Programming Guide. By default, many of the common Core Bluetooth tasks—on both the central and peripheral side—are disabled while your app is in the background or in a suspended state.
That said, you can declare your app to support the Core Bluetooth background execution modes to allow your app to be woken up from a suspended state to process certain Bluetooth-related events. Even if your app doesn’t need the full range of background processing support, it can still ask to be alerted by the system when important events occur.
Even if your app supports one or both of the Core Bluetooth background execution modes, it can’t run forever. Foreground-Only Apps. Discovering and Advertising Network Services. OS X and iOS provide four APIs for discovering and advertising network services: NSNetService—A high-level Objective-C API suitable for most app developers.CFNetService—A high-level C API suitable for use in Core Foundation code.DNS Service Discovery—A low-level C API suitable for cross-platform code. This API also offers more flexibility than the higher-level APIs.Game Kit framework—A high-level Objective-C API that provides peer-to-peer communication support for games, both locally (using infrastructure Wi-Fi and Bluetooth) and globally over the Internet.
In addition to these APIs, iOS offers the Multipeer Connectivity Framework, which provides support for discovering and communicating with instances of your app and related apps on nearby devices using infrastructure Wi-Fi, peer-to-peer Wi-Fi, and Bluetooth. As a rule, you should use Game Kit only for game-related peer-to-peer networking. Bonjour Service Overview A Bonjour service advertisement consists of three parts: To Learn More.
iPhone Bluetooth Programming. Ne of the neat features available in iPhone OS 3.0 is the GameKit framework. The GameKit framework contains APIs to allow communications over a Bluetooth network. Using these APIs, you can create peer-to-peer games and applications with ease. Unlike other mobile platforms, using Bluetooth as a communication channel in iPhone is way easier than expected. Hence, in this article, I will show you how to build a simple application that allows two iPhone or iPod Touch devices to communicate with each other. Creating the Project Using Xcode, create a new View-based Application project and name it as Bluetooth. In the BluetoothViewController.h file, declare the following object, outlets, and actions: #import The GKSession object is used to represent a session between two connected Bluetooth devices.
In the BluetoothViewController.m file, add in the following statements in bold: #import "BluetoothViewController.h" #import Text Field Round Rect Button Perform the following actions: Ios - How to get list of available Bluetooth devices? Welcome. Smart Devices List. iOS 7 SDK: Core Bluetooth - Practical Lesson - Tuts+ Code Tutorial. The Core Bluetooth (CB) framework provides the resources your iOS apps need to communicate with devices that are equipped with Bluetooth low energy (BTLE) technology. This tutorial will guide you through the evolution of CB from iOS 5 to iOS 7. Additionally, you will learn how to configure a Core Bluetooth central and peripheral, how to communicate between them, and inherent best programming practices when working with CB. The Core Bluetooth tutorials are divided in two parts. The first one covers the theoretical aspect of Core Bluetooth, while this tutorial is a complete practical lesson. This tutorial's objective is to teach you how to use the Core Bluetooth framework.
We assume that you know the basics of Xcode and iOS since we will only focus on the Core Bluetooth data. All views are already in place and properly defined. The SERVICES.h file contains two unique UUIDs. Note that this lesson needs two iOS devices to work properly. It is a required protocol method. Performing Common Central Role Tasks. Devices that implement the central role in Bluetooth low energy communication perform a number of common tasks—for example, discovering and connecting to available peripherals, and exploring and interacting with the data that peripherals have to offer.
In contrast, devices that implement the peripheral role also perform a number of common, but different, tasks—for example, publishing and advertising services, and responding to read, write, and subscription requests from connected centrals. In this chapter, you will learn how to use the Core Bluetooth framework to perform the most common types of Bluetooth low energy tasks from the central side. The code-based examples that follow will assist you in developing your app to implement the central role on your local device. Specifically, you will learn how to: In the next chapter, you will learn how to develop your app to implement the peripheral role on your local device.
