BUG: ST40 transmit throws error with empty frames.

For the empty frame, how do you fill below struct? Beside set meta[0].udw_size to 0, do you also set both data_size and meta_num to 0?

struct st40_frame {
  struct st40_meta meta[ST40_MAX_META]; /**<  Meta data  */
  uint8_t* data;                        /**<  Handle to data buffer  */
  uint32_t data_size;                   /**<  Size of content data  */
  uint32_t meta_num;                    /**<  number of meta data  */
};
