I'm new to this forum so sorry if i'm posting this in the wrong place, but I was looking for some help with my project. I'm trying to create a device that will read the battery percentage of the phone and control power to the phone based on its percentage. I was wondering if it was possible to use Bluetooth to read the battery percentage without making a custom app that will send the data to the Arduino.
I'm using an Adafruit "Bluefruit LE Shield" to send and receive Bluetooth. It can be found here:
I've tried using the guide, but I'm new to all this stuff so I'm very confused. If you could help that would be great. Thanks in advance.
