This article mainly explains "how to develop CF Bluetooth module with C #". The content of the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to develop CF Bluetooth module with C #".

Basic points

First of all, it is clear that it is impossible to complete the development only by understanding the relevant knowledge of C # development, because it is related to the driver hardware. We must have some understanding of C++ development. But for simplicity, we don't want to use C++ to write half a line of code, and all the coding work is done with caches, that is, the development environment we use only needs to use Visual Studio.net and no other editors.

As a preparation for developing programs that drive hardware of this kind, you need to understand the basics of C++, know what header files are all about, and know how managed code interacts with unmanaged code. Because the core of this article is to explain how to develop. Net CF Bluetooth communication module, so the above preparation knowledge is not described.

Development of CF Bluetooth Module with C #

To do the development of Bluetooth communication module, it is natural to know what Bluetooth communication is all about. In my opinion, Bluetooth communication should be similar to infrared communication module. Of course, from the developer's point of view, this should be the case after abstraction. Of course, there are many differences between Bluetooth and infrared communication. How to say this in object-oriented design? I think there must be a lot of people who understand it better than I do. Well, that's our basic idea. I have looked up articles about Bluetooth development on the Internet, and many people treat Bluetooth communication as a serial communication in .net CF development, which is also good, but I don't like it very much, because it is not developed for Bluetooth, in other words, in the process of use, you need to manually open Bluetooth, pair, connect, establish a serial channel, and then open the application. You also have to set up a serial port in the application, which is very troublesome for the end user. In my opinion, such a solution under the name of Bluetooth communication is simply …... Say no more, the book goes back to the original.

In infrared communication, we know that the DeviceID of a device is an array of Byte, so what does the DeviceID of a Bluetooth device look like? I think we all know very well that this is a string of hexadecimal numbers separated by ":". In infrared communication, generally speaking, infrared does not have states such as on or off, but Bluetooth has three states: on, off and discoverable. Infrared has no security settings, and Bluetooth has security settings, so we need to pair Bluetooth devices, while infrared communications need it.

We look at. Net's Socket address family has IrDA, but there is no Bluetooth-related address family, this is the problem we need to solve.

Thank you for your reading, the above is the content of "how to develop CF Bluetooth module with C #". After the study of this article, I believe you have a deeper understanding of how to develop CF Bluetooth module with C #, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
