Android Bluetooth Low Energy (Android Low-power Bluetooth) Android 4.3 (API Level 18) has introduced core functions of Bluetooth Low Energy
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 s

before. But then I chatted with my little friends before realizing that all of this is conditional on you having to catch all the key packs at the first match (if you only have 1 ubertooth means you only have 1/3 chance). Unfortunately, many devices will remember each other after the first match has been completed. The next communication will not be re-matched again. So to make this kind of attack more realistic, perhaps studying how unpairing would

, work and play more efficiently. Intel plans to provide next-generation ultra-portable devices in the first half of 2006. At the Intel Information Technology Summit, many managers and engineers discussed the plan together with the development team. Paul Otellini, Chief Executive Officer of Intel, opened the curtain of this "ultra-mobile" session, announcing that "we will launch a new product next year [2007, its

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 traditiona
Now with the broadband speed of the power, the assembly of a high configuration of large-screen computer is a very good life experience. But in the daily life want to use such a large screen of computers to watch high-definition video first need to download, most of the time users will choose to download when not using the computer, which compares to the cost of electricity, and today's energy-saving and environmental protection can not be echoed. So

The most power-saving wifi in history. June 3, at the 2015 Taipei Computex Electronic exhibition, Rui-core Microelectronics Rockchip announced the launch of a global minimum power wifi-rki6000 with a third party, which makes WiFi power consumption and BT4.0 LE Bluetooth is equivalent to low power consumption, using only 20mA Ma, 85% less than the average WiFi power consumption of existing IoT
). Then we remove any unnecessary status bits. The calculation method comes directly from the Sensortag document.To show this data on the interface, we use the arg1 and arg2 two member variables of the Message, and we multiply it by 100 before converting it to the desired int value. After that, we'll divide by 100 to return a float value. As before, the code for the UI will not be shown here, but it will be in the source code.If we run the program, we can see the Celsius temperature and humidity
