Hello!
My steps:
1 - Full working dfu over ble on nrf52840-dk + nrfutil + nrf52840 Dongle
2 - Change transport BLE -> ANT + nrfutil + ANT USB Stick 2, ANT USB(two different sticks)
I think there is some problem with the driver libraries, but what?
Embedded device enter to dfu mode and send messages over ANT. Observ ANT found device type 10, trans type 49, device number 11548
