Problem PPK used with Power Profiler App latest version

[Marlene]

Hi,

I have the Power Profiler Kit PCA63511 used on top of the dev kit PCA10040. I am trying to measure the power consumption of my custom hardware implementing nrf52832 using the Power Profiler App.

I connected my custom board acc to Measuring current on custom hardware with an nRF5 DK

I started the Power Profiler App (latest version) but it seems to be only compatible when used with the PPK2 but not with the PPK that I am using --> I am required to select a device, I would expect a list of available devices (PCA10040 in my case) to be displayed, like in former version of the power Profiler App, but it is not the case.

Please tell me how whether:
to use the latest Power Profiler App in combination with PPK or 
to downgrade the Power Profiler App to a version compatible with PPK (I tried already downgrading to https://github.com/NordicSemiconductor/pc-nrfconnect-ppk/tree/release/2.3 following recommendation here https://devzone.nordicsemi.com/f/nordic-q-a/69755/how-to-downgrade-power-profiler-application but it does not seem to apply to MACOs)

Thanks a lot in advance! 
Regards,

Marlene

Hi Marlene, 

Did you try a different USB port?

The PPK1 can work with the latest Power Profiler App, but not all features are available for PPK 1 though. Mostly the missing features are related to triggering since PPK1 does hardware triggering and there are some limitations. The sampling rate is also lower on PPK1.

 Do you close the Power Profiler App, update the files and reopen the app to source the files again?

Hi Amanda,

Thank you for your feedback and sorry for my late response.

I connected the Power Profiler Kit PCA63511 used on top of the dev kit PCA10040 per USB to my Mac. I tried different ports on the MAC. (Btw, I connected the USB cable to PCA10040 board and not to the Power Profiler Kit). Whatever MAC USB port used, the Power Profiler App does not detect my device (PCA10040).

Actually I checked again and I did downgrade to the version 2.3.0 of Power Profiler App --> But the Power Profiler App still does not detect my device (PCA10040 in my case). The Power Profiler App version 2.3.0 supports engine "NRFConnect 3.3.0" and my current NRFConnect engine is 3.6.1. So I would like to try installing version 3.3 of the pc-nrfconnect-launcher. I downloaded the version 3.3 of the pc-nrfconnect-launcher from https://github.com/NordicSemiconductor/pc-nrfconnect-launcher/tree/release/3.3. Now, how do I downgrade the pc-nrfconnect-launcher? 

Thanks!
Best regards,
Marlene

Hi Marlene, 

Do you also try other USB cables? Can other apps of nRFConnect like Bluetooth Low Engey or Programmer detect the device?

Uninstall nRFConnect and install the version you want. Here is the download link https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-desktop/Download#infotabs

Hi Amanda,

I solved my problem... I only had to use the SELECT DEVICE button.

Thank and sorry for the inconvenience.
