代码如下：
#define ESP_BLE_MESH_SERVER_RSP_BY_APP 0 /*!< Response need to be sent in the application /
#define ESP_BLE_MESH_SERVER_AUTO_RSP 1 /!< Response will be sent internally */
static esp_ble_mesh_gen_onoff_srv_t onoff_server_2 = {
.rsp_ctrl.get_auto_rsp = ESP_BLE_MESH_SERVER_AUTO_RSP,
.rsp_ctrl.set_auto_rsp = ESP_BLE_MESH_SERVER_RSP_BY_APP,
};
看注释不明白，请问怎么理解这两种应答？
