Earlier this year, Microsoft confirmed that it would bring the GATT Server APIs for WIN10 mobile devices, later this year. GATT agreements are important for wearable equipment services, such as smart bracelet, smart watch, etc. Microsoft employee Clint Rutkas at the end of September that the Bluetooth team is working to add the

Android Bluetooth Low Energy (Android Low-power Bluetooth) Android 4.3 (API Level 18) has introduced core functions of Bluetooth Low Energy (BLE, Low-power Bluetooth) and provided relevant APIs through which applications can scan devices and query services, characteristics (attribute feature) of a read/write device ).

Android4.3 (API level 18) introduces a built-in platform to support the central role of BLE, while providing APIs and app applications for discovering devices, querying services, and reading/writing characteristics. Unlike traditional Bluetooth (Classicbluetooth), Bluetooth low power (BLE) is designed to provide more significant low power consumption. This allows Android applications to communicate with low

Android 4.3 (API level 18) has started to introduce the core features of Bluetooth low energy (BLE, Bluetooth) and provides APIs that enable applications to scan devices, query services, The characteristics (attribute feature) of the read-write device. Compared to traditional Bluetooth, BLE is designed to significantly reduce power consumption. This makes it poss

Many developers are developing BLE peripheral devices, which often contain the device Information Service (DIS) services that this article is anxious to introduce , It is a very good way for the maker of equipment, software and hardware version control, production information disclosure. It is therefore recommended that you include this Standard service defined by the SIG at the time of development. On the bluetooth SIG official website, check the De

It is expected that BLE will be the Bluetooth application in Tv/dvd/stb/media player, remote control, game control handle and wireless mouse device.3.5 Smart HomeBLE can provide light control, temperature control, humidity control, safety lock control, door and window control of low-power, high-security solutions.
