We are working with BlueCove (Java Bluetooth library) for years now without any issue. Now, we have a successor of the current BT-Module, which is BT122 (Silabs) and it starts making fun with me.
It works with a regular BT-Virtual-Com-Connection in combination with a terminal-tool e.g. teraterm.
BUT: BlueCove the library used so far won't work any more. It cancels the connection with the below displayed window-messages.
On calling Connector.open(url) I always get
[BLUECOVE] will throw exception javax/bluetooth/BluetoothConnectionException(Failed to connect; [10064] A socket operation failed because the destination host was down.)
The counterpart of the connection, which is the BT-Dongle BT122 says the following messages, which basically means the connection is closed as well.

What remedies can I try for such a case?
