@Huzefamaz1 please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```

Please also use triple backticks around your compiler error message in your second post.

If you can’t find the backtick symbol on your keyboard please copy/paste the ones I’ve provided above.

Pete.

Huzefamaz1 · July 26, 2021, 2:37pm

Dear sir
thanks for your prompt reply yes i will did

PeteKnight · July 26, 2021, 2:44pm

If you’re using a WROVER board, then un-commenting #define USE_WROVER_BOARD would be a good start…

What version of the Blynk library do you have installed?

Pete.

Huzefamaz1 · July 26, 2021, 3:15pm

Dear sie thanks for reply
#define USE_WROVER_BOARD
this i allready Define sir still same issue Sir i am using this verson sir 1.0.1

PeteKnight · July 26, 2021, 4:00pm

Try deleting all of the Blynk libraries (using file manager) and re-installing using the IDE.

Pete.

Huzefamaz1 · July 26, 2021, 4:01pm

Dear sir
thanks for reply ok i will do now sir

Huzefamaz1 · July 26, 2021, 4:31pm

Dear sir
yes i did still same issue sir “Error compiling for board ESP32 Wrover Module.” showing this

What happens if you open the latest Edgent ESP32 example, add-in your template details and try compiling that?

Pete.

Huzefamaz1 · July 26, 2021, 4:42pm

Dear sir thanks for Replying
Yes sir I will try that as well Still showing same ERROR sir this issue is since from last week still I can’t settle please help me

I have no idea what this means.

Pete.

Huzefamaz1 · July 27, 2021, 12:24am

Dear sir
When I use BLYNK.egent then only have this issue sir I use normal Blynk (legency) no issue sir

John93 · August 16, 2021, 2:51am

Hey there.

Try to delete the not used libraries.

Huzefamaz1 · August 16, 2021, 2:55am
