If you are trying to connect a WDSS or LabQuest Stream (LQ-STREAM) to a Windows 10 or 11 computer, you can use a Go Direct® Bluetooth® Adapter (GDX-RADIO).

Note this will not work on older versions of Windows, nor original LabQuests, and it will not make the WDSS work on macOS 11 or newer, (that is caused by limitations in the OS, not a hardware issue with the computer.)
