startDiscovery impossible

[openmotion]

Hello

i try to use your library with a simple code
bluetooth = new Bluetooth(this);

    bluetooth.setBluetoothCallback(bluetoothCallback);
    bluetooth.setDiscoveryCallback(discoveryCallback);

    if(bluetooth != null) {
        try {
            bluetooth.startScanning();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

but i have this error

java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.bluetooth.BluetoothAdapter.startDiscovery()' on a null object reference

It's because you haven't called bluetooth.onStart(). Take a look at the README.

Yes it's possible
I can connect to the device with the default tchat app from Google. I am searching for a library able to manage jpg file transfer

The library does not support BLE.
Of you run the app in the repo does it connect without problem ?
Socket timeout might happen few times before connecting successfully..
