Extended logging using Power Profiler Kit.

[Sujan Nag]

Hello Everyone,

I am using Nordic's Power Profiler Kit to estimate the current consumption of an external board. I have been able to configure it properly and getting results on the nRF Connect v2.3.0 - Power Profiler, (screenshot attached)

However, I am getting readings of only 120 seconds, 

My query is, is there any way to get readings for at least 24 hours. I understand this might be outside the current capabilities of the power profiler kit software, hence I am open to writing any small program or script which can read the data intended for the power profiler kit and store it in a log for at least 24 hours.

Any help would be appreciated.

Thanks and Regards

Sujan Nag.

Most likely 24 hours would be a stretch too long. You can have a look at the source code for the ppk SW here. You can change the const variable in line 42 (BUFFER_LENGTH_IN_SECONDS). I would be careful to increase this value all too much, as it requires quite a bit of memory. You might be able to get 10 to 20 minutes of logging if you have enough memory & CPU power, but I doubt you'd be able to increase this value much more than that. If you increase the value too much, there might be some unintended memory consequences, so be careful.
