/*******************************************************************************
**
** Function AVDT_WriteDataReq
**
** Description Send a media packet to the peer device. The stream must
** be started before this function is called. Also, this
** function can only be called if the stream is a SRC.
**
** When AVDTP has sent the media packet and is ready for the
** next packet, an AVDT_WRITE_CFM_EVT is sent to the
** application via the control callback. The application must
** wait for the AVDT_WRITE_CFM_EVT before it makes the next
** call to AVDT_WriteDataReq(). If the applications calls
** AVDT_WriteDataReq() before it receives the event the packet
** will not be sent. The application may make its first call
** to AVDT_WriteDataReq() after it receives an
** AVDT_START_CFM_EVT or AVDT_START_IND_EVT.
**
** Returns AVDT_SUCCESS if successful, otherwise error.
