This article will detail the principles, features, and advantages and disadvantages of wireless bluetooth. Through this article, I hope you will have some knowledge about the infinite Bluetooth.

ObjectiveWith " calculators " and " video players " We've been able to start developing some more decent apps.Today, we're going to start making a " Bluetooth chat " app. This application is actually very simple, there is no cool interface, is one-on-one, through Bluetooth connection two devices, let two people send each other information.Do not think it is too boring, no practical, in fact, we just want to

Configuring the Raspberry Pi 3 is a Bluetooth-enabled connection.This allows for file transfer, or audio, etc. can be used, can bring some convenience.How do you do it specifically? I practiced a bit, found that it is possible, the following intercept some of the relevant commands and so on for reference.One. Bluetooth pairing between Raspberry Pi and mobile phone:Raspberry Pi 3 directly support

Bluetooth Low Energy (BLE) technology is a low-cost, short-distance, interoperable and robust wireless technology. Work on a license-free 2.4GHz ISM RF band. It has been designed for ultra-low power (ULP) wireless technology from the start.It uses many intelligent means to minimize power consumption.Bluetooth low energy technology is used in variable connection intervals. This interval can be set from a few milliseconds to a few seconds depending on t

Bluetooth SIG is developing the next generation of Bluetooth specifications. This new specification, known as high-speed Bluetooth, will support high-speed file transmission and video stream applications. At first, the Bluetooth SIG only adopted the WiMedia ultra-broadband (UWB) technology to implement this new protoco
