Espressif Systems ESP8266EX - Events Triggered When Wi-Fi Connection State Changes

!
3. Sample Codes
6. Compile the application program, generate firmware and download it into the ESP8266
module.
7. Power off the module, and change it to operation mode; then power on the module and
run the program. Connect a PC or other Stations to the ESP8266 SoftAP.
!
Result:
ESP8266 works as SoftAP, and the following information will be printed when a Station is
connected to it:
station:󰲧c8:3a:35:cc:14:94󰲧join,󰲧AID󰲧=󰲧1
3.2.5. Events Triggered When Wi-Fi Connection State Changes
1. The event monitor Wi-Fi_set_event_handler_cb monitors ESP8266’s Wi-Fi connection
state, either when it is working as Station or SoftAP, and executes a user callback when
the connection state changes.
2. Sample code:
