Hey, I bought the Laird Connectivity Bluetooth LE-only PTS dongle listed on: https://support.bluetooth.com/hc/en-us/articles/360049018492-What-is-the-difference-between-the-Profile-Tuning-Suite-PTS-Dongles- as I was hoping to have an easy to use Bluetooth LE only device for testing. But the device only shows up as a serial device under kernel 6.5 from my distribution. Is there anything specific that needs to be done for that device to be usable as a Bluetooth adapter under Linux? Or does it only work with the PTS? I spotted the ability to run specific software on the micro-controller itself when powered on, but nothing specific to using it as an adapter: http://assets.lairdtech.com/home/brandworld/files/BL654%20USB%20Dongle%20User%20Guide%20v1_0.pdf Full lsusb output for that device: Bus 001 Device 018: ID 1915:521f Nordic Semiconductor ASA Nordic Open DFU Bootloader Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x1915 Nordic Semiconductor ASA idProduct 0x521f bcdDevice 1.00 iManufacturer 1 Laird Connectivity iProduct 2 Nordic Open DFU Bootloader iSerial 3 E1BB9211FA41 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x004b bNumInterfaces 2 bConfigurationValue 1 iConfiguration 4 Default configuration bmAttributes 0xc0 Self Powered MaxPower 100mA Interface Association: bLength 8 bDescriptorType 11 bFirstInterface 0 bInterfaceCount 2 bFunctionClass 2 Communications bFunctionSubClass 2 Abstract (modem) bFunctionProtocol 0 iFunction 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 1 bInterfaceClass 2 Communications bInterfaceSubClass 2 Abstract (modem) bInterfaceProtocol 0 iInterface 0 CDC Header: bcdCDC 1.10 CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 CDC ACM: bmCapabilities 0x02 line coding and serial state CDC Union: bMasterInterface 0 bSlaveInterface 1 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 16 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 10 CDC Data bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Device Status: 0x0001 Self Powered Cheers
