In this case, :cpp:member:`trans_len` is set to :cpp:member:`length` instead of the actual transaction length. To meet the actual transaction length requirements, set :cpp:member:`length` to a value greater than the maximum :cpp:member:`trans_len` expected. If the transmission length is shorter than the buffer length, only the data equal to the length of the buffer will be transmitted. -.. only:: esp32 - - ..
