0x00 PrefaceIf you want to see something new when you open this article, I'm sorry this article isn't the one you're looking for. Because strictly speaking, this is just a finishing article. There was nothing in my discovery, nor in my actual case. Because I don't have a fun Bluetooth low-power device on hand yet. The whole story is based on what Mike Ryan has published over the years.0x01 BLEWhat is ble? B

1. Introduction The last article, "Windows 8.1 low-power Bluetooth development," describes how to create a Low-power Bluetooth application on the Windows 8.1 platform, and takes TI's sensor tag as an example, giving code steps and demos. In fact, many
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 Bluet

Attribute points RF 2.4-ghz Bluetooth Low energy compliant and proprietary RF on-chip systems Supports 1 Mbps, 2 Mbps data transfer rates at Kbps, Kbps – Excellent link budget, enabling If there is no external remote application Front – Programmable output power of 0 dBm – Excellent reception sensitivity ( -94 dbm output power 1 Mbps), selectivity and bloc
). 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

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 energy consumption is half of the ori

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 devices.
