As the accessory of mobile communication, choose Traditional Bluetooth (Classic BT) and low power consumption Bluetooth (BLE) to compare and discuss the process; First clear our function is to use mobile phone with the attachment of communication, to achieve mobile viewing status (data Flow direction: Accessories-> mobile phone), and control accessories (data flow direction: Mobile phone-> accessories). The

The Bluetooth mouse we purchased last week has been back. fortunately, it was the first time I used a wireless mouse. It was good to feel that there was no tail restriction and it was very convenient. There are two aspects to my worries. On the one hand, there are still limitations in buying such a thing online, I have never touched it myself, but I am very enthusiastic about the seller.

Then we go to the Super button and find "settings" as shown in the figure. 3. Then in the go to the Super button we find "Change computer settings" Click to enter, as shown in the following figure. 4. Then we find "Computer settings" below the "computer and equipment" shown in the following image. 5. Now we will see a "

). 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

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

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

Brief This book is from the CSR Bluetooth protocol architect, is the Bluetooth domain Daniel's work, but overall it seems that the book is relatively simple. Summary Basic Concepts Bluetooth Concept The basic idea of low power consumption is that the connection is transient, and when you need to do something or check it, you can quickly create a connection, fini

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
