PPKII "Device must be programmed, do you want to proceed?"

andyduarte0192

Hello Slight smile

I'm trying to connect muy Power Profiler Kit II to my PC, and when I choose the device from the list it pops-up:

I clicked 'Program' and after I supposed it's finished, it takes me back to the 'Select device' list:

If I click 'Open DFU Bootloader' nothing happens. And if I click 'No' in the first picture, it stays 'Connecting' forever...

What can I do?

    EDIETD!!!

    I noticed this, in the device manager, when I connect the PPK-II, 4 COM ports appear:

    The two at the bottom I don't know what they are. I uninstall them but when I reconnect the PPK-II they re-appear

    And now when I open the Power profiler app, and select the device, there are two options:

    The one at the bottom is the COM3 and COM14 (when I uninstall them, the 'Unknown' device option disappear).

    So I select the 'PPK2' option and stays 'Connecting' foerever...

    Here I share the log window:

    Hello, 

    I was not able to reproduce your issue on my side. I also got the prompt for programming the device. No issues during this process.

    Yes, this is known and have been reported internally. Nothing related to the PPK usage.

    Do you have anything connected to the PPK? What port on the PPK are you connected to with USB? 

    Could you please activate verbose logging in the Power Profile app and retry to connect? You'll find the verbose logging button under "About". Afterwards, could you please provide the log file from "Open log file" after trying to connect to your PPK?

    Thanks.

    Kind regards,
    Øyvind

    Hi,

    No, there is no need to buy a new PPK. 

    Can you please try following the steps in the video attached. This way you can try to reprogram the PPK to see if that helps. 

    Kind regards,
    Øyvind

    Unfortunately the video focuses on the nRF Connect for Desktop window and does not show the other windows.
