Do you mean that you aren’t able to click on the link I provided, aren’t able to understand what it means, or something else?
I’d suggest that if you are still having problems after you’ve read through the topic that I linked to then you start a new topic of your own, explaining EXACTLY what you are trying to achieve, what hardware you are using, what version of Blynk you are using, what version of the Blynk Python library you have installed, what you see in your serial monitor, and any other information that might conceivably be of use when trying to assist you with your problem.
