+nrf52840 Dongle Firmware
+-------------------------
+This is the nrf52840 Dongle Firmware for the integrationtests
+
+Setup 
+1. install `nrfutil`
+2. install `nrf5sdk-tools` via `nrfutil install nrf5sdk-tools`
+3. `pip install west`
+4. `cd nrf_dongle_fw`
+5. `west init`
+6. `west update`
+7. `west build -b nrf52840dongle/nrf52840 zephyr/samples/bluetooth/hci_uart`
+8. Create update package
+```
+nrfutil nrf5sdk-tools pkg generate \
+         --hw-version 52 \
+         --sd-req=0x00 \
+         --application build/zephyr/zephyr.hex \
+         --application-version 1 \
+         nrf52840dongle_hci_uart.zip
+```
+9. find dongle  (on macos: `ls /dev/tty.usbmodem*`)
+10. flash firmware: ``nrfutil nrf5sdk-tools dfu usb-serial -pkg nrf52840dongle_hci_uart.zip -p /dev/tty.usbmodemSOMESTRING``
