I have an App Designed application that collects data from an Arduino Pico.
The Pico runs individual trials with accurate to submillisecond timing. MATLAB starts each trial as soon as the previous one is complete. Data is saved in tables as I found that writing to disk after each trial took too long. Even so, the time between trials is longer than it should be AND it can be extremely long on occasion. I’ve plotted each trial duration and the timing of the end of one to the start of the next. Any ideas as to why MATLAB occasionally takes long breaks? I’ve tried clearing variables between each trial (doesn’t seem to affect my app tables). Removed calls to get time of day (useing Pico Timer for data) various other attemps with Profiler but no luck since the error is rare. Copilot wasn’t much help either.
I tried updating to version R2025a and that was much worse!

Any help much appreciated. Code for the app is here, it’s big:
