)

#include <include/bluetooth/fast_pair/fhn/fhn.h>

Register the ringing callbacks in the FHN module.

This function registers the ringing callbacks. If you declare at least one ringing component using the

CONFIG_BT_FAST_PAIR_FHN_RING_COMP 

Kconfig choice option, you shall call this API before you enable Fast Pair with the bt_fast_pair_enable function. Otherwise, the enable operation fails.

You can call this function only in the disabled state of the FHN module (see bt_fast_pair_is_ready function).

This function must be called in the cooperative thread context or in the system initialization context (SYS_INIT macro).

Parameters

cb	Ringing callback structure.

Returns

0 if the operation was successful. Otherwise, a (negative) error code is returned.
