Power Profiler v.4.2.0 + PPK2 - Plot stops working after a while

[jmaha9000]

Reporting this here as the project GitHub asked that bugs be reported via DevZone.

The latest Power Profiler v4.2.0 has introduced an annoying issue - when running the Power Profiler for a long time (sourcing 3.7V power and collecting logging data, set to 1,000 samples/sec, sampling forever), typically leaving it to run overnight, after a whlie it stops logging new data. Pressing Stop and Start doesn't restart the graph, it just stays blank despite sourcing power to the DUT. If I close + restart the Power Profiler app, it works again. Additionally, I can deselect the PPK2 device and re-select it, and then starting logging works again.

I'm running macOS Sonoma 14.5 on a MacBook Pro with an M1 Max chip.

In fact, it appears the UI may be getting into some kind of half-disconnected state with the device. It still visually appears to be connected, but I can't change the voltage (that option disappears despite the on/off toggle for the power source remaining).

Hello,

I have reported it internally, will update as soon as I hear back.

Here's a video of the app in this nonfunctional state. This time it appears to be fully connected, with all controls visible, but stopping/starting the graph results in a blank graph.

I should mention too that this happens consistently when the app is left running overnight. In previous versions I used to leave the app running for long periods of time with no issues; the plot would stop when the buffer filled up, but I could stop/start recording no problem.

Hello,

The team is looking into it, I can see one of the developers have asked the following question, let me know if you have any feedback:

What buffer size did they use to have (and that would be before version 4)
