Whilst I have successfully followed this guide
Github code example which is sufficient for my implementation goal I want to know more about the details about the request body. What minimum is required and what extra value does the other parameters give when I make the post request?
More specifically what does this line do
client.println("A string with params in here); do? It does not print to the serial monitor.
I also found this example ESP8266: HTTP POST Requests - techtutorialsx that is using the ESP8266HTTPClient library. I manage to make request to the dummy server but failed using it together with things speak, probably used it wrong. I find it difficult to find any documentation of how to use the library? Is anyone aware of where "beginner friendly" documentation is for the library?
I hope I am not asking to much in one post I just try better understand where I can find good documentation.
