The BL654 Dongle is not presenting as a Bluetooth Adapter
The BL654 is a stand-alone Bluetooth dongle with its own Bluetooth stack - it does not rely on the host stack and should present as a USB Serial COM Port or nRF52 SDFU USB COM port under Ports in Device Manager depending on which variant of the dongle was purchased.
smartBASIC variant (451-00003)
The 451-00003 will need to be programmed with a smartBASIC application in order to configure it for BLE operations.
- Nordic/Zephyr variant (451-00004)
The 451-00004 will need to be programmed with a Nordic or Zephyr application in order to configure it for BLE operations.
Note: With the Nordic/Zephyr variant it is possible to load an HCI sample application to the dongle and it will then expose an HCI interface and register as Bluetooth/BLE adapter on the PC operating system. See this FAQ page.Additional documentation for programming the dongle is available from the BL654 Product Page.
