Measuring and Improving Serial Performance / Serial.flush() Blocks Forever on Nano 33 BLE Sense

@UKHeliBob
Why would this website give the option to link to another Arduino Forum topic if you are saying we have to just reiterate everything that was concluded in said linked topic?

This prohibition only makes sense if we operate under the premise that past topics on this site might be lost but that isn't the case, correct?

For the record, I do operate under this premise when linking to content from external sites, and always try to summarize said content, to be considerate to future readers.

You are not being considerate right now by veering this topic further and further away from the intended goal.
