I would like to create an app permitting to recover data from a raspberry pi in bluetooth! The goal would be to display the data in graphical form over time, when a play button is pressed.
For that I have 2/3 questions, first of all how can I receive data from an rpi connected by bluetooth to a telephone? And can I make a database recovering date, time of the mobile and the values implemented on another page and allowing to display a graphs according to time on the main page?
Thank you 🙂
