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 Band: UHF radio waves using ISM bands from 2.402GGHz to 2.480GHz (including protection band

Analysis from the Bluetooth Technology: 1. Distance: many sellers on the market announced support for 20 m, 30 m, 50 m, etc. In fact, this is the distance from Bluetooth support for sellers.Is there two standard classes? 1 and class? 2, class? 1 supports a standard distance of 100 m and class2 supports a distance of 10 m. In fact, the distance is notIn the case of obstacles, class? 2 can support up to 10-20

created, using Gatt.connect (); Re-establish the connection.* But in this case the result of the test is that reconnecting takes a long time.* The solution is through GATT = Device.connectgatt (this, false, Gattcallback); A new Connection object is established, which is obviously much faster than the previous method.* However, the direct result of multiple creation of the GATT connection object is that more than 6 GATT has been created and will no longer be connected to any devices, since the n

Implementation of Bluetooth protocol stack under Linux. Linux open Bluetooth protocol stack mainly includes IBM's Bluedrekar,nokia company's affix, axis company OPENBT and the official protocol stack BlueZ. We mainly face the BlueZ to discuss. The BlueZ base code is completed by Maxim Krasnyansky. Includes: Hci,l2cap,rfcomm and implementation of basic socket. He works for Qualcomm (Qualcomm). Marcel Holtma

At startup, it takes some time to fully load and initialize the Bluetooth protocol stack. You can use bth_namedevent_stack_inited to check the protocol stack initialization, which is defined in % _ winceroot %/public/common/SDK/INC/bt_api.h. To open this naming event, you must use OpeneventFunction. // Determine whether the Protocol Stack has bool fstackup initialized = false; For (INT I = 0; I

This small game is based on Bluetooth communication implementation (a bit redundant), C/s structure, but did not implement AI. The use of the process is to open the server first, waiting for the client to connect successfully after the game can be started. There is also worth saying is that every time is the client first, the new start is also! Because these days to see movies and go out to play more time, so in the details of the program is not very

Graduation design is to do the topic of smart home, to do a mobile phone Bluetooth app, and the next computer to achieve data transmission; I've never done Android before, but I'm pretty good with qt,c++, so I use eclipse to feel quite handy, and the Java language is very similar to C + + in many places, so I personally feel , C + + people, Java is certainly not a problem. Not familiar with Java, you can refer to my article Java syntax: different from
