Hi every one.
I am doing a project using blynk, with a need a chart to simulated a ECG Graf.
I decided to use one char that is not in the plane base, so you need to upgrade your plane to use it.
A bought the plane the cost like 12$, but the Graf was still not enable for me to used.
Can any body tell me what is going on. Did a bought the wrong plane ?
This is the Chart and the plane that a bought:
Can any body help me please ?
