3. Compile the application program, generate firmware and download it into the ESP8266
module.
4. Power off the module, and change it to operation mode; then power on the module and
run the program.
Result:
For example, when ESP8266 functions as a Station, the process of how it is connected to
a router is shown below:

3.2.6. Read and Set the MAC Address of ESP8266
1. ESP8266 can work in Station+SoftAP mode. The MAC addresses of the Station and
SoftAP interfaces are different. It is guaranteed that the MAC address of every chip is
