nrfutil is not found as sudo. I also added full access to /dev/ttyACM0 to verify but nothing changed

I have tried running as an administrator in the windows command prompt and it makes no difference.

Could be a stupid question, but are you running as sudo?

Here are the last lines regarding the error. We noticed also that we have the same error on a Raspberry Pi when we use two times pc-ble-driver using a different python script (nrfutil and a custom script we made). We need to unplug and plug the nRF52-DK board to make it work.

There are no known issues with nrfutil and linux distros as far as I knnow. I am afraid that I am out of ideas, could you attach the output of nrfutil v3.1.0?I'll then discuss this issue with the developer responsible for nrfutil.

Any update? I removed every nrfutil/pc_ble_driver related stuff from my computer, then installed nrfutil (3.1.0) from scratch and I always get the same error: Failed to open. Error code: 13

The error is raised in pc_ble_driver_sd_api_vx.py::sd_rpc_open.

I call: nrfutil dfu ble -ic NRF52 -pkg hex/dfu_release_v2.1.1.zip -p /dev/ttyACM0 -n "EQS_BL20" -f

I did this a few times without sucess. Do I need to install pc-ble-driver from source also?

I've tried running this on every nrfutil.exe release on windows with no luck, v2.3.0 included. Same problem trying to run from sources on Ubuntu.

If you're using a Linux distro, then you have to compile it from the source. Could you uninstall nrfutil using pip uninstall nrfutil? Sometimes you have to run the command several times if you have had older versions of nrfutil installed. After uninstalling you should go through the Running and installing from source steps in the nrfutil repo, found here

Any idea for Linux distributions?

RE: command line nrfutil dfu ble

bjorn-spockeli — Thu, 15 Jun 2017 07:28:13 GMT

We've added a nrfutil.exe in the nrfutil v2.3.0 release, found here. Could you try running that?

RE: command line nrfutil dfu ble

I can't run any example from pc_ble_driver_py (advertising.py and heart_rate_collector.py) for the same reason.

nRF Connect is working fine... but I need to run nrfutil...

RE: command line nrfutil dfu ble

Cyril — Wed, 14 Jun 2017 14:42:58 GMT

Same error here. It flashed the connectivity firmware before the error.

The issue seems to be pc_ble_driver_py called from nrfutil... I'll keep you updated (On Ubuntu 17.04)

Are you using a nRF52 DK as the device on the pc side? Have you flashed the board on the pc side with the connectivity firmware? If not, then try adding the -f option to flash the firmware.
