dult_bt_adv_data_fill()

int dult_bt_adv_data_fill	(	const struct dult_user *	user,
		struct bt_data *	bt_adv_data,
		uint8_t *	buf,
		size_t	buf_size,
		const struct dult_bt_adv_data *	adv_data )

#include <include/dult/bt.h>

Encode the DULT location-enabled Bluetooth advertising payload.

This function can only be called if the DULT user was previously registered with the dult_user_register API.

Serializes the DULT data (UUID, network ID, near-owner byte, and optional proprietary data from adv_data) into buf and populates bt_adv_data to reference it. The caller must ensure that buf remains valid for as long as bt_adv_data is in use.

Parameters

[in]	user	Pointer to the DULT user structure.
[out]	bt_adv_data	Pointer to the Bluetooth advertising data structure to populate.
[out]	buf	Backing buffer for the serialized payload. It must be large enough to hold the fixed DULT header followed by adv_data->proprietary.len bytes; otherwise the function returns -EINVAL.
[in]	buf_size	Size of buf in bytes.
[in]	adv_data	Advertising data to encode.

Returns

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