Is there a list of functions available for each library? As I continue to program my NodeMCU, I would like to know what functions are available and which libraries to include with each program.
i’m not sure, but i think you can find all blynk functions in the docs. and as for the libraries, if you forgot to include a library, you will get mentioned on compile time.
As @wanek mentioned, the documents pretty much sum up the various Blynk commands and functions.
As for which library to include… that is determined, as far as Blynk libraries, by the type of MCU & connection method.
I make use of the Sketch Builder and pick differing devices and connections to see the required libraries.
With the NodeMCU, or most any ESP8266, you will always need
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
Plus any additional libraries for extra features, sensors, etc… based on those add-ons requirements.
