Bluetooth connection instability

Hi,

I had some trouble connecting to the brick via BT.
COM port selection is straightforward and works many times, still sometimes the following errors occur.
- connecting and disconnecting still leaves the device in some pending state –> after restarting the connection (app) it hangs on the EV3 Connect command.

Tried some explicit dispose, some timeouts – no use. USB works like a charm.

Any thoughts, ideas how to attach this problem?

Thanks, Attila
