Espressif ESP8266 User Manual

F. First Run
Now we’re all set to run the WeatherStation software for the first time. Click on the Upload
arrow and wait until the compilation and the transfer have ended. Now you should see the
OLED display lighting up and displaying a WiFi icon. The module should now be trying to
acquire access to the wireless network you have defined earlier.
This is just the beginning. In the next chapter I’ll give you some ideas of what else you can
build with the WeatherStation hardware.
