Thank you for the swift answer!
Ok, always active is good news. But a scan interval of 1.28 seconds sounds a bit worrying. Does that mean that a) the latency is always 1.28 seconds or b) that the latency is at least 1.28, but can vary depending on how long from an interval I happen to press the button? This is important. If a), then I can learn to compensate for this, to always time the sound effects 1.28 seconds from the press of the button. Not fun, but doable. If b), how long could the variable times be? This makes a huge difference for the usage I had in mind.
Also worth mentioning is that this is a Flic 1. Are there any differences for Flic 2.0?
