Hey,
I need to create an application that, when a certain message arrives through Bluetooth, alerts other phones (triggers actions in other phones with a “receiver” app). I’ve seen that I need to use online databases, but I still haven’t been able to make it work: how do I create a database? How do I set both the sender app and the receiver app on the same database? How do I read a value from database? I just need to store a value, like a number or letter.
Thank you
