When the device is powered up and flashed, the WiFi will be initialised in AP_STA mode. You can connect to the created AP (default_ssid) with the password: test12345 You should be assigned IP address and everything should be fine.
In order to stop the wifi, execute UART command via the Termite or simmilar UART emulator. The command is "stop_wifi_ap". After a few seconds, you can start the WiFi again by executing "start_wifi_ap" command.
As you run the example, you will see the LED blinking, according to the previously defined period. For the addressable LED, you can also change the LED color by setting the pStrip_a->set_pixel(pStrip_a, 0, 16, 16, 16); (LED Strip, Pixel Number, Red, Green, Blue) with values from 0 to 255 in the blink.c file.

Note: The color order could be different according to the LED model.
The pixel number indicates the pixel position in the LED strip. For a single LED, use 0.
