Race condition between Connect timeout and a successful connection leaving active connection stranded

[jasaw]

If a Bluetooth LE connection is established while the connect timeout is triggering, flutter_blue will think that the connect call has timed out and failed but the Android OS still maintains the Bluetooth connection. Calling disconnect on flutter_blue does not disconnect the BLE connection.

The best way to trigger this bug is to set connect timeout to 4 seconds, and run hundreds of bluetooth connect and disconnect to a device that has weak signal strength (-90dB to -95dB). I have tested this on Android 8.

Hello, this plugin is obsolete and maintenance is stopped. Use the continuous and active package : flutter_blue_plus
