Hi,
I'm trying to plan out a project to accomplish the following and could use some guidance.
GOAL: I'd like to create an Android APP that allows me the ability to change the value of a variable on my ESP32 via a bluetooth connection.
Let's assume for development purposes the variable is the time delay in the basic Blink.ino sketch.
What approach would be the easiest to take with this type of project?
Thanks,!
