The previous article describes the communication between the Android phone and the BLE terminal, while the most common ble terminal should be the ibeacon base station advocated by Apple. Ibeacon technology based on BLE, it is characterized by the broadcast of external messages, mobile phones do not need to connect to the Ibeacon base station can also obtain its information, is mainly used to do indoor positioning and marketing information push, in the

Transferred from: http://blog.csdn.net/pwei007/article/details/6015907The Android platform supports Bluetooth network protocol stack, which realizes wireless transmission of data between Bluetooth devices.This document describes how to use the Bluetooth API provided by the Android platform to achieve communication between Bluetooth devices, the communication between Bluetooth devices consists of four steps:

device collection that gets the return value through Bluetoothadapter.getbondeddevices () to get the device.Method1) Createrfcommsockettoservicerecord (uuiduuid) creates and returns a bluetoothsocket based on the UUIDThis approach is also the purpose of our acquisition of Bluetoothdevice-creating Bluetoothsocket2) getaddress () with Bluetoothadapter3) GetName () with Bluetoothadapter3.BluetoothserversocketDescribeA Bluetooth listening port.

OverviewSince Android 5.0, Google has added support for Android phones as a low-power Bluetooth peripheral, the service side. Enables mobile phones to communicate with each other through low-power Bluetooth.Development stepsIn fact, this function only needs to be divided into setting up the broadcast and setting up a server two parts to completeSetting up the serverThe main operation of this step is bluetoo

Recently, with the popularity of smart wearable equipment, intelligent medical care and intelligent home, Bluetooth development is very important in moving. Because of the company's needs, we studied the Bluetooth 4.0 application in Android. Here are some of my summaries. 1. Let me introduce some of the nouns in Bluetooth 4.0:(1), GATT (gneric attibute profile) Through BLE connection, reads and writes the attribute class small Data Profile general

One: Introduction to Bluetooth Kits The Android platform provides a Android.bluetooth package that implements the Bluetooth API for communication between Bluetooth devices. There are a total of 8 classes, and the four commonly used classes are as follows: Bluetoothadapter class Represents a local Bluetooth adapter. It is the entry point for all Bluetooth interactions. With it you can find other Bluetooth devices, query the bundled device, instantia

Android Bluetooth systemBluetooth is a radio technology that supports short-range communication (typically 10m), which allows wireless information exchange between a wide variety of devices.Bluetooth modules in the Android systemAndroid includes support for the Bluetooth network protocol stack, enabling Bluetooth devices to wirelessly connect to other Bluetooth devices to exchange data.By using the Bluetoot

The previous article explains the basic use of Bluetooth in Android, and this article delves into the hidden APIs in the next Bluetooth context. People who have used the Android system setup (Setting) know that pairing and pairing can be established after a Bluetooth search, but the functions of these two functions are not given in the SDK, so how do you use both of these features? This paper uses the refle

I wanted to write this article long ago and I have forgotten it. Before the beginning of the development of Android to engage in Bluetooth development, good head big! Studied for half a month to get it done. Now self-organized Bluetooth development framework, this framework is relatively simple, but hope to help Bluetooth development friends. Of course, personal technology is very food, the shortcomings please guide.Bluetooth Open step:1. Understand t

()--Get the local Bluetooth device GetName ()--Get the name of the local Bluetooth Getremotedevice (String Address)--Obtaining a remote device based on a remote device's MAC addresses StartDiscovery ()--Bluetooth device starts searching for peripheralsbuletoothdevice--remote devices. It contains the same methods as Bluetoothadapter, no longer tired. View Code //Get local Bluetooth Adapter instance Bluetoothadapter adapter = Bluetoothadapter.getdefaultadapter ();

by Bluetoothdevice the object, specify the steps: Use the method Createrfcommsockettoservicerecord (UUID) in the Bluetoothdevice object to obtain the Bluetoothsocket. A UUID is a matching code. Then, call the Connect () method. If the remote device receives the connection, they will share the Rffcomm channel during the communication and return connect. Note: the Conncet () method is also a blocking call,

First, understand the Android operating system Android was first founded by Andy Robin (Andy Rubin) and was acquired by Google in 2007, and Google has achieved great success with its Android operating system on smartphones. 1, the characteristics of the Android operating system The

Android phones are typically connected to the SPP protocol device with the client's role (connected to the digital sensor of the Bluetooth module), the connection process is: 1. Use Registerreceiver registration Broadcastreceiver to obtain Bluetooth status, search equipment and other information; 2. Use of Blueadatper search; 3. Obtain the

When using the mobile phone, Bluetooth communication brings us a lot of convenience. So how does Bluetooth develop on Android phones? This article illustrates the knowledge of Android Bluetooth development in a practical way. 1, the use of Bluetooth response authority xml/html Code 2, configure the native Bluetooth module Here first to understand the Bluetooth operation of a core class blue
