Sergnrf: Would it be possible for you to share the bootloader project where you have added DFU USB support?

Hi, I am also working on this. In the link you posted, there is only an example compatible with the nrf52832 development board. We are currently using the nRF52840 with USBD. We already combined all the changes between USB and BLE and are initializing 2 transports, but it fails on initializing the BLE transport when we include the code for USB, as it explains in that link, but it wasn't clear what the fix was for it failing on ble_stack_init().

You can add comments on what was changed in your unofficial example? You can add all files unofficial example so that would it open without errors in Keil?

Hi Sergef,

as far as I know there are no plans for releasing an official example that supports both the USB and the BLE transport layer.

We do have an unoffical example that supports BLE+UART, see https://devzone.nordicsemi.com/f/nordic-q-a/35431/dfu-over-ble-and-usb.

Best regards

Bjørn
