@Hu_n_Dinh you seem unwilling to follow the Blynk community rules when it comes to providing the sort of information that is needed for community members to assist you, or when it comes to providing code or serial output in the correct format.

For this third time, you should read this topic before creating a post…

and provide as much of the information requested as possible.

When you post serial monitor output please do not post screen shots, copy and paste the text.

When you post this text to the forum, ot when you post code, it needs to have triple backticks at the beginning and end so that it displays correctly. This is also explained in the link I provided.

In your previous attempts at posting about this issue you said that you were using a NodeMCU with the Mega. You now say that it’s an ESP-01.

If you are using a ESP-01 with your Mega then reading this might help to point you in the right direction…
