1. Define Edit Broadcast

The wireless communication realized in the movement is also known as mobile communication, and people call the two together as wireless mobile communication.

 

2. Editing and broadcasting of technical principles

Wireless communication is a communication method that uses the characteristics that electromagnetic wave signals can propagate in free space to exchange information. In the field of information communication in recent years, wireless communication technology is the fastest-growing and most widely used. The wireless communication realized in the movement is also known as mobile communication, and people call the two together as wireless mobile communication.

 

The development of modern telecommunications over 150 years from the very beginning of the telegraph is the result of the hard work of thousands of scientists, engineers and researchers from all walks of life. Only a few of them who were solely responsible for the invention became famous, and most of the inventions that culminated were the work of many individuals. Here are some of the historical figures who played an important role in the development of radio communications.

 

Q8 By the way, I have two question.

1)Where is MAC address stored? Is it in SPI ROM?

2)Before MAC address was reprogramed, the WLAN communication was unstable.

However, after it was  macupdated,  the WLAN communication was stable.

In addition to the MAC address, other settings have been rewritten, which I think has stabilized the system.

Is there anything you can think of?

A: 

1)  MAC address is stored in flash .

2) We think that if Mac is not programmed successfully, ,the calibration is not working.
