BlueZ - Bluetooth protocol stack for Linux - is same as thermos bottle?
-
After few "try this and watch for smoke ..." Setting "to" parameter to zero / "0" makes the Bluez function return correct result in unspecified time. Setting the "to" parameter to "lower then best guessed" value in mS - the function will return "-1" - a customary error value. Same as thermos bottle will keep hot contents (coffee?) hot and cold contents (beer ?) cold - BUT how does it know to keep hot hot and cold cold?

It doesn't; it just slows the rate of change to the state of equilibrium with its environment.

Well I suppose that anything that intends to make something cold or something hot would need to have some way of measuring the temperature. Otherwise one might expect that self heating coffee mug sitting on the desk to burst into flames.

I have been around the block few times - broke few class thermos bottles too... never found any remnants of temperature measuring devices , not even the "skinny ones".... intended for a...l usage....
