power profiler app does not recognize ppk2

ziv123

hello Nordic

i am using ppk2 pca63100, 

working on linux (manjaro), installed the nrfConnect v3.9.3 with power profiler v3.3.0

1. when i connect a device i have to close both power profiler and nrfConnect for recognision of the connected device (which i connect to the 'data/power' usb port which is strange

2. when seeing a device on the port it remains unknown and it is not recognized as ppk2 device

3. there is no 'start' or normal ui for the conected unknown ppk2 

hope you can guide me what is missing or what needs to be configured

p.s. the same ppk with same cables is identified on another pc with manjaro

hope to read from you soon

best regards

    Hi

    Do you have the same version of nRFConnect, Power profiler app, and manjaro on the computer that is able to detect the PPK2 correctly? Are you not able to see the UI of the Power profiler app at all? Something could have gone wrong during the installation of nRFConnect or the power profiler, so you could try uninstalling and reinstalling the apps altogether. Does any of the other nRFConnect apps work as intended with a DK for instance?

    Best regards,

    Simon

    same version of nRFConnect, power profiler app and manjaro on compared computer

    when i try to run the downloaded file (after setting executable permissions) i get an error:  

    "libva error: /usr/lib/dri/i965_drv_video.so init failed"

    don't know if that is the issue or some other bug

    but other app like scan on bluetooth is not enabled .. son't know if it an issue with connecting to my pc ble but its enabled by me and still not working

    hope to read you soon

    best regards

    Hi

    What exactly is "the downloaded file" you refer to? Have you tried uninstalling and reinstalling either or both power profiler application and nRFConnect for Desktop? Does I.E. the Programmer app work, which doesn't need Bluetooth, and just a connection to a DK.

    You can also try switching the USB cable you're using, or if you're using a USB hub, try connecting the USB with the PPK2 on it directly to a USB port on the computer.

    Best regards,

    hi 

    i downloaded this version 3.9.3 from n:

    i have connected the ppk to the pc usb port and bot via docking, and i used the same usb cable as in the compered pc which did recognise the device

    tried to use the programmer in the nrfconnect with my board connected with a jlink and it did not recognized it either

    Hi again

    Okay, that at least points towards this issue not being caused by the Power Profiler app specifically. Can you try updating your J-Link drivers and nRF Command line tools to the latest version as well, as that might affect the connection.

    You can also check to make sure the working and non-working computers have the same USB driver versions.

    Best regards,

    Simon
