Yes, for BT I look for a raspberry device name. For the COM port I get the serial port description from the registry and search for the Silicon Labs driver.

Hi,

yes, but my Chesstimation module reports as BT device name "Certabo".
I will still add the name of the driver at Certabo when searching for the COM driver. This should prevent for invalid connections.
Next version will stored the BT hardware address separat for each board.

@Tobias: With this changes, you will have a workaround for your second BT module: You configure this as TabuTronic Cerno board
