Question: Is there a way to detect a pause in data reception?

[betov75]

Hi! I need to detect when data stops entering for at least X ms. For example, when data is entering, if, for example, 300 ms passed between two lines, a function is launched. Can this jeopardize the perofmrnance a lot?
Thank you very much for your answer(s)

You could either:

• keep track of the last time a handler was called (assuming you catch all incoming events) and update that time in each handler as well as check for the duration you want.
• start a timer that you'd cancel/restart on each handler, there are many ways to do that depending on the way you run your program (sched-based, signal.alarm based, threading.Timer based etc, read through those and pick the one you want)

Neither option should really be costing much, just make sure you're not blocking (never call time.sleep).
