nrfutil dfu ble failed to open Win 10

I try to load my nRF52 with app via ble from windows 10 laptop.

nRF52 dev kit is loaded with the Softdevice and Bootloader from nRF5_SDK_12.1.0\examples\dfu\ble_dfu_send_hex\test_images_update_nrf52.

I have no problems to load nRF52 dfu_test_app_hrm_s132.zip from Mobile nRF Toolbox.

I try to do as admin:

"nrfutil dfu ble -ic NRF52 -n "DfuTest" -p COM5 -pkg dfu_test_app_hrm_s132.zip"

from windows 10 python2.7.12(nrfutil2.0.0/pc_ble_driver_py0.8.0) only version installed.

but get open failed exception (access denied):

"C:\Python27\lib\site-packages\pc_ble_driver_py\ble_driver.py", line 126, in wrapper raise NordicSemiException('Failed to {}. Error code: {}'.format(wrapped.name, err_code)) pc_ble_driver_py.exceptions.NordicSemiException: Failed to open. Error code: 13

I can see nRF52 device "DfuTest" in win bluetooth device list.

Any ideas?

  • Hi Kent, nrfutil uses the pc-ble-driver,a serialization API for our SoftDevices that needs Nordic Hardware( either a nRF51 Dongle or nRF51/52 DK) flashed with the connectivity firmware connected to your computer in order to use it to perform DFU over BLE on another nRF5x device. Thus when you use the following command

    nrfutil dfu ble -ic NRF52 -n "DfuTest" -p COM5 -pkg dfu_test_app_hrm_s132.zip
    

    nrfutil will look for a nRF5x device connected to COM5, that is flashed with the connectivity firmware, and then use it to send the DFU packets to a second nRF5x device that is advertising as "DfuTarg" (by default) since you have not specified which device it should update. You can upload the connectivity firmware by adding the -f option to the command above, i.e.

     nrfutil dfu ble -ic NRF52 -n "DfuTest" -p COM5 -f -pkg dfu_test_app_hrm_s132.zip
