nrfutil dfu ble failed to open Win 10

[Kent]

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?

You're running cmd.exe as administrator right? However, you have to use nrfutil v1.5.0 if you're using the Secure Bootloader from SDK v12.1.0, please see our Github page, here is the link.

Thanks! yes Im running cmd.exe as administrator.

I installed nrfutil v1.5.0 by the following as admin:

1. install Python 2.7.12

2. python -m pip install --upgrade pip

3. python -m pip install -U setuptools

4. python -m pip install pyinstaller

5. unzip pc-nrfutil-1.5.0 and cd to it

6. python setup.py install

7. pyinstaller nrfutil.spec

running as admin "nrfutil --help" but gets:

File "C:\Python27\lib\site-packages\pc_ble_driver_py-0.8.0-py2.7.egg\pc_ble_driver_py\config.py", line 48, in sd_api_ver_get raise RuntimeError('Connectivity IC identifier conn_ic_id is not set') RuntimeError: Connectivity IC identifier conn_ic_id is not set

I have already run:

nrfjprog -f NRF52 –-chiperase --program dfu_test_softdevice_bootloader_s132.hex --verify

You have to uninstall nrfutil v0.8.0 as it will casue a conflict with the newer version. Also check that your path variable is pointing to the correct version.

Seems pc_ble_driver_py-0.8.0 still be installed even if I force it away :(

I now did the following:

1. delete entry in %USERPROFILE%\AppData\Local\pip\cache

2. delete existing pc-nrfutil-1.5.0 folder

3. unzip pc-nrfutil-1.5.0 and cd to it

4. uninstall existing Python and delete the folder

5. install Python 2.7.12

6. open cmd.exe as administrator

7. python -m pip install --no-cache-dir -r requirements.txt

8. python nordicsemi/main.py

but still get the:

Traceback (most recent call last): File "nordicsemi/main.py", line 50, in from nordicsemi.dfu.dfu_transport_ble import DfuTransportBle File "C:\Users\4light\Downloads\pc-nrfutil-1.5.0\pc-nrfutil-1.5.0\nordicsemi\dfu\dfu_transport_ble.py", line 48, in from pc_ble_driver_py.ble_driver import BLEDriver, BLEDriverObserver, BLEUUIDBase, BLEUUID, BLEAdvData, BLEGapConnParams, NordicSemiException File "C:\Python27\lib\site-packages\pc_ble_driver_py\ble_driver.py", line 63, in nrf_sd_ble_api_ver = config.sd_api_ver_get() File "C:\Python27\lib\site-packages\pc_ble_driver_py\config.py", line 48, in sd_api_ver_get raise RuntimeError('Connectivity IC identifier conn_ic_id is not set') RuntimeError: Connectivity IC identifier conn_ic_id is not set

Hi Kent, do you have a nRF51 Dongle or another nRF52 DK that runs the connectivity firmware in addition to the nRF52 DK with the S132 and the bootloader right?
