在ch573mesh例程里面只找到了heartbeat-publication的API

int bt_mesh_cfg_hb_pub_set( uint16_t net_idx, uint16_t addr,

    const struct bt_mesh_cfg_hb_pub *param );

int bt_mesh_cfg_hb_pub_get( uint16_t net_idx, uint16_t addr );

以及该API对应的结构体

struct bt_mesh_cfg_hb_pub

{

    uint16_t dst;

    uint8_t count;

    uint8_t period;

    uint8_t ttl;

    uint16_t feat;

    uint16_t net_idx;

};

与此同时还发现了heartbeat-subscribe对应的结构体

struct bt_mesh_cfg_hb_sub

{

    uint16_t src;

    uint16_t dst;

    uint8_t period;

    uint8_t count;

    uint8_t min;

    uint8_t max;

};

但是没有发现其对应的API，请问有没有对应的API
