#include "BlynkSimpleEsp8266.h"

Development Tools IDE 1.x
1

Something I cannot seem to understand. I include #include "BlynkSimpleEsp8266.h" in the sketch, I have it in the library. and compile never finds it. I have tred putting it everywhere, in a folder, in the same place as the 8266 sketech is. I'm sure its a cockpit error, but i'm stumped... What am I not doing??
Thanks, Henri Monnier

That file is part of the Blynk library. You need to install the entire library, not just that file. Here's how to install it:

  1. Select Sketch > Include Library > Manage Libraries from the Arduino IDE's menus.
  2. Wait for the update to finish.
  3. In the "Filter your search" field, type "blynk".
  4. Press Enter.
  5. Click on "Blynk by Volodymyr Shymanskyy".
  6. Click the Install" button.
  7. Wait for the installation to finish.
  8. Click the Close button.

You should now be able to compile your Blynk sketch.

I have installed the entire Blynk library as described above (numerous times) but only a small portion of the libraries are recognised.

I have a new fresh install on the IDE and this is the first thing I am trying to do following the same issues on previous installs

e.g.

WidgetBridge.h is recognised but
WidgetGPS.h isnt

Same file location, created at the same time from the library manager.

Only 8 of libraries are reconised

Thanks

Please provide a detailed description of what you mean by "recognized".

I have the same problem, I'm working with Blynk and with an Arduino UNO trough a ESP-01, and after including the Blynk libraries it shows the error on screen, not when compiling, but when uploading. I'm currently using Arduino IDE V1.8.12. tried updating libraries through Arduino IDE, they load but the same error appears.

it still uploads but shows this on screen.

"Librería inválida encontrada en C:\Users\Master\Documents\Arduino\libraries\SerialESP8266wifi: No encontrado archivos de encabezado (.h) en C:\Users\Master\Documents\Arduino\libraries\SerialESP8266wifi"

(Spanish for invalid libraries found in....)

I solved the problem just by deleting the entire folder mentioned in the error message....

By "recognized" I'm sure he means that it is not turning into Orange colour when we add it as #include <BlynkSimpleEsp8266.h>
I'm facing the same problem

Library developers can define keywords for their libraries. The Arduino IDE colors the names matching the keywords of any installed library whenever they occur in the sketch.

Some library authors define all the keywords.

Some library authors forget to keep their keywords updated, so not all relevant names are colored.

Some library authors don't follow the documentation for how to correctly format their keywords, so the IDE doesn't recognize them.

Some library authors don't bother to define any keywords.

In addition, the IDE's keyword highlighting system is fairly crude. You might find that some keywords are highlighted even though you aren't using that library at the time. This becomes more common the more libraries you have installed.

So it's best to not assign too much importance to the color of things in the Arduino IDE. The keywords highlighting is purely cosmetic. It has no affect on the compiler.
