i use Blynk Library ver 1.3.2
Clearly you didn’t take any notice of this…
or this…
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:
```
Copy and paste these if you can’t find the correct symbol on your keyboard.
Then delete the screenshot of your compiler error message and replace it with the text (copied and pasted) from your IDE, and place triple backticks at the beginning and end of that too.
And, if you want help with this, tell us which version of the Blynk library you are using.
Pete.

Are you going to post your compiler error message text?
Pete.
Hi Peter
I have the same issue.
I’m using the BlynkEdgent and the 3 mentioned lines are on the top of the code.
On the first (main) page.
The error message looks like this:
In file included from C:\Users\Sandor\Documents\Arduino\KozpontiFigyeles-OTA-08_clone\KozpontiFigyeles-OTA-08_clone.ino:40:
C:\Users\Sandor\Documents\Arduino\KozpontiFigyeles-OTA-08_clone\BlynkEdgent.h:16:2: error: #error "Please specify your BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME"
16 | #error "Please specify your BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME"
| ^~~~~
exit status 1
Compilation error: #error "Please specify your BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME"
Thank You
Your triple backticks need to be immediately above and below your compiler error message, not at the beginning and end of your post. You can use the pencil icon at the bottom of the post to fix this.
Please post your sketch (with triple backticks, as explained above) and tell us which version of the Blynk library you have installed.
Pete.
So instead of editing your original post and fixing the location of the triple backticks you’ve decided to post your compiler error message again!
Are you planning to provide the other information I asked for?
Pete.
Edited my previous message.
Should i include anything else?
Thank You
