Power Profiler II Kit Connecting Forever / Doesn't Connect

DavidDettling

Hi,

I'm unable to get the PPKII kit to "connect" to my PC.  After selecting the device it just says "Connecting..." forever.

Some notes:
- When first connecting the kit it came up and asked me to update the FW, which completed successfully.
- I'm able to force the device back into Bootloader mode and I attempted to update the FW a few more times with the same result.
- I'm using a windows 11 PC with nRF Connect Desktop v5.2.0 and Power Profiler App v4.3.1.  Verified both are the latest versions.
- I tried uninstalling and reinstalling both PPKII App and nRF Connect Desktop.
- I can see and select the device as "PPK2 (F00CD018F83F.  Log info below.
- The LED is blinking green while trying to connect
- I tried the device on another PC and it worked fine and connected right away.  Tried my PC and again it doesn't connect.
- I've used both the Programmer and Serial Terminal nRF Connect Apps with this PC with no issue.
[[UPDATED:
- Tried rebooting PC and attempting with a clean boot with nothing else running.
- Tried removing all other USB connections to the PC except for the PPKII.
- Tried multiple USB cables and multiple ports, and used the same USB cable on the other PC where the connection worked.
- Tried manual flash using the Programmer tool and file pca63100_ppk2_1.2.4_db16a94.hex found at: C:\Users\<your_user>\.nrfconnect-apps\node_modules\pc-nrfconnect-ppk\firmware
- Verified connected to USB DATA/POWER connection.  Also tried connecting to both at the same time.

Device Manager shows the following while trying to connect:

I searched the forums, but didn't easily find anything else.

Any help would be appreciated.  Thanks.

    It's Windows 11 PC.

    Also tried rebooting PC and attempting with a clean boot with nothing else running.

    And tried removing all other USB connections to the PC except for the PPKII.

    Still same issue.

    Hi,

    When first connecting the kit it came up and asked me to update the FW, which completed successfully.

    Did you get the message shown below when you tried to connect to your PPK II?


    I assume you chose Program instead of No. Is this correct?

    Have you been presented with the same pop-up window after FW update was completed and you disconnected and then reconnected your PPK II?

    Did you have 2 devices (F00CD018F83F and 000519002569) connected initially? What was the second device?

    It might be that your firmware update got interrupted. You could try to change USB cable and/or USB port or program firmware manually using Programmer application. You could look at this ticket for more information on how this problem could be resolved.

    Best regards,
    Dejan

    Hi Dejan,

    Thanks for your response.

    Yes, I did get that message when I first connected my device.  The FW update completed successfully, but it did not connect after rebooting itself.  After removing and reconnecting the device is still does not connect, and it no longer asks for the FW to be updated.  The device did work on another PC after FW update, so I assumed the update was successful.  

    I tried multiple USB cables and multiple ports, and used the same USB cable on the other PC where the connection worked.

    The other device in the the log was a Segger JTAG that was connected.  I disconnected it, but I still don't get a connection in the PPK2.  Here is the log without the other device:

    Thanks for the info on direct programming.  I was able to do that.  My file name was:
    pca63100_ppk2_1.2.4_db16a94.hex

    It said it completed successfully in 9 seconds.  I rebooted the PPK2 and tried the Power Profiler app again, but I still get the same thing.  It just says connecting forever with the green LED slowly flashing...

    Any other ideas?
    Thanks again.

    Have you tried to downgrade to mentioned tested version of SEGGER J-Link?

    Hi Dejan.

    Yes v8.18 of Segger J-Link was tried first, as can be seen in the first of the two logs posted.  I updated to v8.74 (2nd log) to see if it would make any difference and it didn't.

    I again tried uninstalling all versions of Segger J-Link and all Nordic Tools and just reinstalling only nRF Connect Desktop, and I'm still seeing the same issue.

    I went back to the PC where this is work.  I verified:
    - Same nRF Connect for Desktop Version (v5.2.0)
    - Same Segger J-Link version (v8.18)
    - Same Devices showing up in the device manager and same versions for those devices.
    - LED is flashing green in the same manner before connecting.

    Here is the log for the working PC using the same PPK2 and same USB cable:

    11:31:50.463 PPK started
    11:31:50.464 PPK opened

    It's looks to be the same as the failing PC until the last two lines that never happen.

    Is there any other logging information that could be looked at?

    Hi David, 

    Have you tried to downgrade your Power Profiler app?

    Can you provide the output when you run "nrfutil device list"?

    Best regards,
    Dejan

    Hi Dejan,

    Yes, I have tried older versions of Power Profiler App.
    I tried the current v4.31.  I also tried v4.3.0 and v4.0.0.  You can't go back farther than v4.0.0 without also rolling back the Desktop App.  If you think there is a specific version I should try, let me know.

    Here is the output of nrfutil device list:

    F00CD018F83F
    Product                    PPK2
    Ports                        COM27, vcom: 0
