Blynk.Edgent Compilation ERROR: 'WIFI' was not declared is this scope

Need Help With My Project
1

I’m using an ESP32 and I took the example code and this message appears. How do I resolve it?

Compilation ERROR: ‘WIFI’ was not declared is this scope.

I’m trying to use Blynk.Edgent.
I’m using an ESP32 WROOM 32 - I selected the “ESP32-WROOM-DA Module” from the device list.

It helps if you do a quick search before starting a new topic…

I have the same problem and I does not find the solution …

What core version are you using?

Pete.

I am using at the time an ESP32S ( with esp WROOM), but I have exactly the same problem with an ESP32-DevKit (with esp WROOM) and with an ESP32-H2-Devkit M1

That doesn’t answer my question.
You’ve clearly either not read, or not understood the solution in the link I provided in post #2 of this topic.

Downgrade to v2.0.14 of the ESP32 core and it’ll fix your issue.

Pete.

Thank you.

Compiles perfectly now !

I do not understand how it possible, the simple example is not working 6 monthes…

The Edgent example is far from simple, and has been broken by 3rd party changes to the ESP32 core files - something beyond Blynk’s control.

If there was a simple fix to the example then I’m sure it would have been updated to resolve the issue.

There’s a simple workaround.

Pete.

With the updated Espressif ESP32 3.x.x board configuration, I find the Blynk Edgent_ESP32.ino example does not compile.

Solutions is simple: insert this line BEFORE the #include "BlynkEdgent.h" statement
#include "WiFi.h" // <============== I HAD TO ADD THIS TO BLYNK'S EXAMPLE FOR IT TO COMPILE

The updated Edgent_ESP32.ino Example is below. This has been working for me.
