But the no Bluetooth adapter is detected. When the nRF52840 Dongle is plugged into a USB port on a Linux machine, the serial device /dev/ttyACM0 is available and the SMP server is able to communicate with the mcumgr application. My approach is to make a USB composite device consisting of the Bluetooth device (CONFIG_USB_DEVICE_BLUETOOTH) and a CDC ACM UART (CONFIG_USB_CDC_ACM) which is used as backend for the MCU Manager Support (CONFIG_MCUMGR_SMP_UART). Hi, I am trying to figure out how to make a HCI USB Bluetooth host adapter with device management on a nRF52840 Dongle.
