bt_fast_pair_adv_data_fill()

int bt_fast_pair_adv_data_fill	(	struct bt_data *	adv_data,
		uint8_t *	buf,
		size_t	buf_size,
		struct bt_fast_pair_adv_config	fp_adv_config )

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

Fill Bluetooth advertising packet with Fast Pair advertising data.

Provided buffer will be used in bt_data structure. The data must be valid while the structure is in use.

The buffer size must be at least bt_fast_pair_adv_data_size. Caller shall also make sure that Account Key write from a connected Fast Pair Seeker would not preempt generating Fast Pair not discoverable advertising data. To achieve this, this function and bt_fast_pair_adv_data_size must be called from context with cooperative priority.

This function can only be called if Fast Pair was previously enabled with the bt_fast_pair_enable API.

Parameters

[out]	adv_data	Pointer to the Bluetooth advertising data structure to be filled.
[out]	buf	Pointer to the buffer used to store Fast Pair advertising data.
[in]	buf_size	Size of the buffer used to store Fast Pair advertising data.
[in]	fp_adv_config	Fast Pair advertising config.

Returns

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