First verify that the Bluetooth device is connected to your notebookNext, right-click on the "Sound control" icon in the lower-right corner of the screen---> select the "Play" Settings optionNext select the Bluetooth device line in the playback options, right-click on the option, select "Connect",When you select test, the Bluetooth device will sound the test voic

Windows CE, as a typical embedded operating system, is typical for other embedded systems such as PSOs + and nucleus us by porting Bluetooth applications to widows ce. Because the file transmission application on obex is built on the Bluetooth simulation serial port of RFCOMM implementation, this article introduces the implementation of the

After obtaining the module, please ask zwei to help me fly the module to the Board. The final situation is a bit like a cockroach and a spider, which is hard to solve. After flying the line, use the serial port debugging assistant to send the at # command to confirm that the bluetooth module and the serial port can work normally. As a result, the luck was not g

I recently in the study of embedded serial communication, the task is to write a mobile phone-side remote control to control the double-wheel balance trolley. The interface only takes one hours to write, and the important question is how to communicate with the SPP-CA Bluetooth module that the board is carrying.The Spp-ca module comes with code, and all I use here is the default mode of SPP-CA. Where the ba

Always wanted to write a technical document, but due to the limited self-inductance ability is not able to pen, recently made a on the Android platform to achieve and C language communication to operate the Bluetooth module project, the middle encountered a lot of problems, but also on the internet a lot of information, in the completion of the main functions, there are some people on the internet asked me some questions Writing this document here is

The Bluetooth physical link ACL (asynchronous connectionless), and the other link is SCO (synchronous connection oriented), which is mainly used to transmit data communication with high time requirements. The Bluetooth baseband technology supports two connection types: Synchronous and targeted connections (SCO) and asy

worth a bit praise AH. Program storage for 1k,ram 256 bytes, also with 4K EEPROM, this on-chip EEPROM has not been tested, the next time you want to use, then test it, this feeling is good, even external memory do not have to hang, or a word, province! On-Chip has two timers, timer 0 and Timer 2, only a serial port, but can be reused, equivalent to two serial ports, but this I have not tested.The program r

The Bluetooth physical link ACL (asynchronous connectionless), the other link is the SCO (synchronous Connection oriented) is mainly used to transmit time-demanding data communication.

Win10 after the update, Bluetooth function is gone, there is no option to open the Device Manager, there is an unknown USB device, reboot invalid, reload Bluetooth driver is invalid, Bluetooth in the BIOS is open.Try to find all the methods on the Internet, including Update WIN10 update, update Bluetooth driver, etc. a

eventually trigger the application layer once the corresponding message comes in:As for why, don't say it firstThe rest of the routine process is basically like this!2.2. Serial Port RoutinesThe callback function is used when the serial port is initialized, similar to C #, so the data receive is processed in the callback function ~Above 95 lines, the serial port

* The Android Bluetooth serial app downloaded online is based on Eclipse, but there are problems when importing into as.The last thing I used was to create a new project under as and import the relevant files. However, there are other problems encountered.* Some Bluetooth related function error, prompt similar to this "call requires API Level 8", in the Internet

I have been busy with my work and I still have my papers. Some time ago, I got herpes again. This article describes how to create a virtual serial port on the server and enable the listening thread. Today I will talk about how the client requests the server and establishes a connection. Prerequisites: the client must know the Bluetooth address and channel number of the server to request a connection fro
