Furthermore: obviously, it will depend on the advertising interval, but is there any reccommendation about the advertising timeout? (i.e., time window for advertising every X time -advertising interval- and enough to connect to a central if it is there). My intention is to implemenent that: 1.- Advertising at a certain interval during a certain period (suitable period?) 2.- Sleep for a certain time 3.- Go to 1.-

You need to find a balance between accepted power consumption and accepted time to find the device. How fast you find the device also depends on what scanning window and interval the central uses. This depends highly on your application.

Ways to reduce power consumption during advertising:

reduce the advertising interval
reduce the length of the advertising packets

You can set the advertising interval between 7.5 ms and 10.24 s, if you want to advertise more rare than 10.24 s, you could put the device to sleep, and then restart the advertising.

Please see this question for power consumption estimation for advertising.

This question might be useful as well, focusing on minimizing power consumption in general.
