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:
Wi-Fi_handle_event_cb : event 1
connect to ssid Demo_AP, channel 1
Wi-Fi_handle_event_cb : event 4
IP:192.168.1.126,mask:255.255.255.0,gw:192.168.1.1
Wi-Fi_handle_event_cb : event 2
disconnect from ssid Demo_AP, reason 8

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
