These APIs let applications wirelessly connect to other Bluetooth devices, enabling point-to-point and multipoint wireless features.

This page focuses on Classic Bluetooth. Classic Bluetooth is the right choice for more battery-intensive operations, which include streaming and communicating between Android devices. For Bluetooth devices with low power requirements, Android 4. To learn more, see Bluetooth Low Energy. This document describes different Bluetooth profiles, including the Health Device Profile.

It then explains how to use the Android Bluetooth APIs to accomplish the four major tasks necessary to communicate using Bluetooth: setting up Bluetooth, finding devices that are either paired or available in the local area, connecting devices, and transferring data between devices.

In order for Bluetooth-enabled devices to transmit data between each other, they must first form a channel of communication using a pairing process. One device, a discoverable devicemakes itself available for incoming connection requests.

Another device finds the discoverable device using a service discovery process. After the discoverable device accepts the pairing request, the two devices complete a bonding process where they exchange security keys. The devices cache these keys for later use. After the pairing and bonding processes are complete, the two devices exchange information.

When the session is complete, the device that initiated the pairing request releases the channel that had linked it to the discoverable device. The two devices remain bonded, however, so they can reconnect automatically during a future session as long as they're in range of each other and neither device has removed the bond.

In order to use Bluetooth features in your application, you must declare two permissions. You need this permission to perform any Bluetooth communication, such as requesting a connection, accepting a connection, and transferring data. Your app needs this permission because a Bluetooth scan can be used to gather information about the location of the user. This information may come from the user's own devices, as well as Bluetooth beacons in use at locations such as shops and transit facilities.

Alternatively, on devices running Android 8.

For more on this option, see Companion device pairing. Most applications need this permission solely for the ability to discover local Bluetooth devices. The other abilities granted by this permission should not be used, unless the application is a "power manager" that modifies Bluetooth settings upon user request. Starting in Android 3. A Bluetooth profile is a wireless interface specification for Bluetooth-based communication between devices.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I searched all over the web and I cannot find an answer to this simple question: how to display in j2me a list of all bluetooth devices in the neighbourhood? This site gives a full example. You have a choice of BlueCove or Avetana these too I'm aware of. First, bear in mind that in the emulator you can't detect 'real' Bluetooth devices without a third-party JSR library such as Bluecove it's a desktop implementation for Java Bluetooth.

But when you deploy to a JSR capable phone, it should work. Instead of printing the discovered devices as above, you could always put them into the Hashtable or Vector. The deviceDiscovered method gets called everytime a device is discovered whilst the inquiry is running, and the inquiry usually returns in a decent time a matter of 10s of seconds.

Hi Steven. How to run this Program? Once i run it gives the following error. Hi, I can run this program.Comment 3. Spring Boot is a tricky framework to understand. In this tutorial for beginnners with Spring Boot, we will look at the basics of Spring Boot and help you understand the important concepts — Starter Projects, Auto Configuration, and Starter Parents.

Once you understand that, you should be in a good position to start with the building blocks of Spring Boot. The most important feature of Spring Framework is Dependency Injection. And loosely coupled applications can be easily unit tested.

Spring MVC provides a decoupled way of developing web applications. Spring Boot also provides a few features to make building production-ready applications faster. Can we bring more intelligence into this? Based on these, Spring Boot provides the basic configuration needed to configure the application with these frameworks.

This is called Auto Configuration. Starters are a set of convenient dependency descriptors that you can include in your application. You get a one-stop-shop for all the Spring and related technology that you need, without having to hunt through sample code and copy paste loads of dependency descriptors.

For example, if you want to get started using Spring and JPA for database access, just include the spring-boot-starter-data-jpa dependency in your project, and you are good to go.

The following screenshot shows the different dependencies that are added into our application when you add Spring Boot Start Web into the dependencies of your project. This is a wide variety of components that are typically used to develop web applications.

Spring Boot Starter Web brings them together and provides a simple approach to use them. Any typical web application would use all these dependencies.

Spring Boot Starter Web comes pre packaged with these.

As a developer, I would not need to worry about these dependencies or their compatible versions. Spring Boot provides a wide range of starter projects. Spring Initializr suppports all of them and more. Among the varied range of starter projects and options supported are:. It allows you to create a varied range of Spring Boot-based applications from a very simple UI. Some of the types of applications you can bootstrap are:.

When we create a deployable application, we can embed the server for example, Tomcat inside the deployable. You can run a web application as a normal Java application! An embedded server implies that our deployable unit contains the binaries for the server for example, tomcat. It makes it easy to use data access technologies, relational and non-relational databases, map-reduce frameworks, and cloud-based data services. To make it simpler, Spring Data provides abstractions interfaces you can use irrespective of underlying data source.
