/*------ What Is A Transmission ------*/
/* An user (application) fires a operation (CONNECT/DISCONNECT/PUT/GET/SETPATH/ABORT) to server to do something */
/* The operation is in fact a packet of data which is called Transmission here */
/* A Transmission is composed of fixed 'Field' plus some optional 'HEADER' */
/* For the fixed 'Field', here using obex_transmisson_prepare to reserve the buffer in Transmission */
/* For the optional 'Header', here using obex_transmisson_add_XXX to add it in Transmission */
