Bug with connection

[MkhytarMkhoian]

In the tutorial, you say that the connect function is suspended and waits until device is in connected state, but it's not true. I've got the exception STATE_DISCONNECTED when calling discoverServices right after connect.
To solve this problem, I use callbacks instead of relying on the described behavior above.

This happened because BLE asynchronous itself under the hood. Could we fix API or make clear documentation?

    // Connect a Bluetooth LE device. This is a suspend function that waits until device is in connected state.
    val connection = blinkyDevice.connect(context) // blinkyDevice from scanner

    // Discover services on the Bluetooth LE Device. This is a suspend function which waits until device discovery is finished.
    val services = connection.discoverServices()

I've encountered the same problem, solved it using a suspendCancellableCoroutine() and resolving the future once the connection state changes to CONNECTED.

However, I feel a suspending connect function is not a good design, as there is no proper way to close the gatt without its reference, see #135

Hi,
I'm refactoring the library. A lot of things will change. I'll make sure that connect behaves as in the documentation.
