Power Measuring for nRFConnect nRF52840 devices

[TigerD]

Hi,

I have PCA63511 Power Profiling DK and nRF52840 DK ( and nRF9160-DK )

I was using SoftDevice SDK, and no issues with measuring nRF52840 device. But now I switched to nRFConnect SDK, compiled and loaded into nRF52840 device. But Power Profiler launched from nRFConnect Desktop doesn't show start button when the device is selected.

Did I miss anything?

Thank you,

David

Hi David, 

Can you provide more information on what you loaded into the nRF52840 device? What exactly are you trying to measure on? Will need more information to reproduce on my side. 

Please note that the PPK1 (PCA63511) is not compatible with the nRF9160 DK. For this you will need the new PPK2.

Kind regards,
Øyvind

Hi Oyvind,

I guess it is compatibility issue. But PPKI (PCA63511) is the nRF9160 DK board. It is able to measure the nRF52840/bRF52832 DK boards using SoftDevice SDK, but not using nRFConnect SDK.

Do you have PPK2 board part number for ordering?

Thank you,

David

David, to clarify, the PPK1 and PPK2 does not distinguish between the nRF5 SDK or nRF Connect SDK. It should simply measure current regardless of what SDK is running on the device. Ref. PPK1 measurement system vs PPK2 measurement system.

Have a look at the Power Profiler Kit 2 product page.

 Can you elaborate more on this?

Hi Oyvind,

We bought 3 PPKI and quite a few nRF52840 dev boards, and nRF9160 DK boards. We were using PPKI for power measurement of nRF52 dev boards when I was using SoftDevice. I attached two images to show this. Please review.

But now, I was suggested by your support team to use nRFConnect SDK for nRF52 devices programming, because I was told that your company is not adding any new features into SoftDevice.

Thank you,

What images should I review? What sample are you running from the nRF5 SDK and nRF Connect SDK? Sounds like there is an issue starting the NCS sample.

 This is true. The nRF Connect SDK is the future SDK we urge customers to use. It will implement future functionality The nRF5 SDK is still supported but will not add newer features e.g. Matter or BLE Long Range.
