Perhaps. Sorry, I do not understand what you want to do? "Send the coordinates of the points I marked with a marker" from the Arduino to the esp32 or something else?
To do that you need to know the Marker ID for each Marker; query it and then send the data to a List.
This tutorial might get you started. It does not do what you want to do; it does shows how to gather the information associated with each run time marker ( The type of marker you are using). Knowing how to do that might help you figure out what you hope to do. National Park Tutorial (Markers) updated .
It might be easier to work with design time Markers.
