If we timeout/fail to find a WPS signal, go to #2.If #2 times out or fails or we skipped #2, attempt to run a scan for a WPS signal and connect if we find it.Use that if available to attempt to make a connection to that network, otherwise skip this step.Read the SSID and the password from the configuration.Here are the steps we take to connect to a network: This is relatively straightforward for devices where a network connection is required because we can stall the rest of the application until the connection and configuration takes place, but what about an application like a clock that needs to run continuously while ideally looking for Internet connections or WPS signals in the background? With the default ESP8266WiFi library, this is pretty much impossible. Once the WPS button on the router is pressed, they will connect. What I mean is my devices don't require anything to be done to them other than to be switched on. My IoT devices typically autoconfigure their WiFi connections and support WPS. This is the most involved part of the project, and the main reason I created this project and article, so we're going to spend some time with this subtopic in particular. Conceptualizing this Mess Connecting and Configuring and select each of the zips to install them. After unzipping this, you can go to Sketch|Include Library|Add Zip Library. You'll also need to install all of the libraries in ESP8266AutoConfLibs.zip. You'll know it took if you now have a Tools|ESP8266 Sketch Data Upload option. That is where the ESP8266FS folder needs to go.Įither way, you'll need to restart the Arduino IDE. It is probably something like C:\Program Files (x86)\arduino-1.8.13. I've never done it on Windows, but this is how you do it: You'll need the ESP8266FS folder from the zip. Under there, there is a tools folder and that's where you want your ESP8266FS folder to go. If you're on Linux, you'll want to get the ESP8266FS folder in the zip, and find your Arduino application directory. Now get yourself the latest ESP8266FS zip file here. If there is already a URL present, delimit them with commas. You must go to File|Preferences and add the following to the Additional Board Managers text box: You'll need the usual wires and prototype board. You'll need a 16x2 LCD display with a hitachi interface. You'll need a DHT11 temperature and humidity sensor. You'll need a DS1307 or similar Real-time Clock. You'll need an Arduino Mega 2560+WiFi R3. I'll also be providing you with some libraries that ease the automatic network configuration portion in your own apps. We'll be putting together a clock based on some tutorials, and then writing some witchy code to give it some magic. We're using a clock as an excuse to explore some advanced techniques for IoT devices, even the humble and ironically named Mega. Sometimes, there's more to a device than meets the eye.
