I'm working in an android app that has to "talk" via Bluetooth with a device. App has to be able to send and receive data.
I started to work with BluetoothAdapter but couldn't make it work properly so I leave it for a few weeks. Now I would like to continue with that and I wonder if is mandatory to use the BluetoothAdapter.
The phone is able to find and pair devices itself so why we need BluetoothAdapter? Why don't we use those connections directly and try to "talk" with the paired devices?
Could you help please?
