mobile phones can not join the smart bracelet and other devices. Android4.3 mobile phones are equipped with dual-mode BR, so compatible with Bluetooth 3.0 technology before, can not only communicate with the BLE device, but also with the traditional Bluetooth communication, compared to power consumption, can be as high-speed transmission as traditional equipment. Most smart bracelet uses a single-work ble,

This article from http://blog.csdn.net/hellogv/, reference must indicate the source! Recently, wearable devices have become very popular and technologies have become increasingly popular. One of them is BLE (Bluetooth Low Energy ). BLE is the core Profile of Bluetooth 4.0. Its main function is fast search, fast connection, ultra-low power consumption, and data transmission. Its weakness is its low data tran

exchange of pairing information, which is used to determine the authentication method, as well as whether to allocate and which keys will be allocated in the future. The information exchanged includes: The input and output capabilities of the two devices, such as whether the display screen and keyboard are available. Whether to bind (if bind bit pairs are set ). Whether MITM is required or OOB is used This information will allow the

process like the first time. The first process of pairing is the exchange of pairing information, which is used to determine the authentication method, and whether or not to assign a key and which keys to assign later. The information exchanged includes: Both ends of the device input and output capabilities such as: whether there is a display, keyboard and so on. Whether binding is required (if a bind is set for pairing). Whether to need MITM, whet

Since Android 4.3, BLE (Bluetooth low energy) has been supported on the Android platform. However, there are few BLE applications available on Android, especially in Chinese applications, and hopefully this article will help developers interested in developing BLE applications.
