First, the basic knowledge of Bluetooth1. Bluetooth is a wireless technology standard that enables short-distance data exchange between fixed devices, mobile devices, and building personal domain networks. Bluetooth based device low-cost transceiver chip, transmission distance near, low power consumption.2. Microwave bands: UHF radio waves using ISM bands from 2.402GGHz to 2.480GHz (including protection ban
Bluez-Based C language Bluetooth Programming Source:[Url = ResponseChapter 4 C language Bluetooth Programming Based on bluezThere are many reasons for us to use C instead of other advanced languages such as Python to develop Bluetooth applications. The Python environment may not be suitable for embedded systems. Because the embedded system is large in applicatio
Bluetooth and Wi-Fi clash and the other way reprint from: http://www.bluesoleil.com.cn/information/605.htmlIn the field of short-range wireless communication, Bluetooth and Wi-Fi are a pair of enemies.Their first confrontation appeared in the year 2009. In the year, the Bluetooth Technology Alliance released 3.0 technical specifications, the new technology introd
2nd Section Design PlanAfter the function is determined, it is necessary to start the functional verification around the function, the layout of the interface design, and the planning of the program structure.2.1 Technical VerificationHaving selected the core functions to be done at this stage, we first need to do technical validation of them to see what methods can be implemented. The technical validation also allows us to discover a number of practical problems that we are unaware of in the br
Abstract: Bluetooth is an open global standard for low-cost wireless data and digital communication.Android is the name of an open-source mobile phone operating system based on the Linux platform announced by Google in November 5, 2007. The platform consists of an operating system, middleware, user interface, and application software, it is claimed to be the first truly open and complete mobile software for mobile terminals. By studying the
Wireless Internet access is often seen in many KFC and McDonald's. Do you still envy others for wireless Internet access? In fact, you can do it yourself, as long as your mobile phone has a Bluetooth function. Let's take a look at how to implement it. To enable bluetooth wireless Internet access, you can use the following solutions: Bluetooth wireless Internet ac

Bluez-Based C language Bluetooth ProgrammingThere are many reasons for us to use C instead of other advanced languages such as Python to develop Bluetooth applications. The Python environment may not be suitable for embedded systems. Because the embedded system imposes strict restrictions on the program size, running speed, and storage space occupied, all of these make it impossible for an explanatory langu
Introduction to android Bluetooth Low-energy (LBE) Technology Bluetooth Low-energy (BLE) technology is a low-cost, short-distance, and interoperable Robust Wireless Technology that works in a licensed 2.4 GHz ism rf band. It was designed as an ultra-low power (ULP) wireless technology from the very beginning. It uses many smart means to minimize power consumption. Bluet
What is Bluetooth? Bluetooth is the origin of the Tenth century unification of Denmark and Norway's Nordic Viking king Harald Bluetooth, because the king likes to eat blueberries, gums are blue every day, so called Bluetooth. Modern Bluetooth technology is developed by Ili

In the software development of intelligent devices, wireless interconnection is a very important piece, we can see that the infrared is almost all the standard of smart devices, and
After reading a lot of information and reading a lot of things, I felt that the Bluetooth programming on the VC was messy, and my head was too big. Next I sorted out what I saw and learned (if there were any errors, please correct ):There seems to be more than one way of VC bluetooth programming. The popular method on the internet is IVT's BlueSoleil_SDK, which uses two

The Bluetooth technical specification includes basic connection safety measures. By default, most Bluetooth devices work in unprotected "unsecured" mode. The Bluetooth technical specification also defines two other modes: The third mode guarantees the security of the entire wireless connection, and the second is the security of each authorized application. For be
