//! This sub-module is responsible for advertising explicitly for device
//! discovery purposes. The advertisement will contain the device name,
//! transmit power level (to be able to order devices by estimated proximity),
//! Pebble Service UUID and discoverability flags.
//! Advertising devices will implicitely become the slave when being connected
//! to, so the "slave" part in the file name is redundant, but kept for
//! the sake of completeness.

//! @return True is Pebble is currently explicitly discoverable as BLE slave
//! or false if not.

//! a few seconds. After this, the rate will drop to save battery life.
