Hi,

As of now, we are not informed of any updates regarding this issue. But you could try working on the newer update and hopefully, it will work fine.

Hi,

Are there any updates regarding the power profiler and programmer issue in later nRFConnect? I still use 3.7.1, is it worth updating to later versions now, or are you still working on it?

Hi Peter,

I will report this internally and get back to you with the update. Thank you very much for your time and effort.

Hi again,

I have downgraded to nRFConnect v3.7.1 and it seems the power profiler (v3.1.3) runs much smoother now. It also feels quicker at start compared with the later versions. The nRFConnect also starts up much faster on my pc than with the later 3.9.x. I have also confirmed that I can program the 9160 using v3.7.1 (programmer v1.4.11), something I couldn't do with v3.9.3.

Hi,

I am using programmer v 2.1.0. I'll try to downgrade and see what happens.

Hi Peter,

Could you try again after downgrading to v3.7.1 and let me know if it works fine to verify.? We are getting a few reports on the programmer issue as well. What is the version of your programmer..? We are currently working on a fix for this.

Kind Regards,

Swathy

Hi again,

I am still having this problem using nRFConnect 3.9.3 and profiler v3.3.0. The trace suddenly freezes. It seems to happen, as before, when I leave the profiler sw for some other sw (today I am using only Chrome and TeraTerm). I can't really pin-point when it happens, only that it does happen and quite frequently (which makes me haveing to restart the PPK2). It seems to have appeared in the later version of nRFConnect and I also have problems with the programmer (as others as well). So maybe there is a connection?

Hi,

I use 10ksamples/60min. I tested again, and now it does seem to work. The trace is resumed which makes me wonder if it could have to do with what program I go away to. I know I had the problem when I was using a CAD-tool. This time I was only using the web browser. I'll try some more...

Hi,

This is indeed a weird situation as I am unable to reproduce this. I tried running the power profiler application in the background and it did freeze, but resumed automatically without any action after a few seconds. Are you sure that you are not just hitting the allocated buffer? If you check the sampling parameters in the power profiler, you can see that the maximum time to sample is 432 seconds after which it stops sampling.

Kindly check and let me know.

Regards,

Swathy
