- *
- * @defgroup hci_transport HCI Transport
- * @{
- * @ingroup  app_common
- *
- * @brief    HCI transport module implementation.
- *
- * This module implements certain specific features from the three-wire UART transport layer, 
- * defined by the Bluetooth specification version 4.0 [Vol 4] part D.
- *
- * \par Features supported
- * - Transmission and reception of Vendor Specific HCI packet type application packets.
- * - Transmission and reception of reliable packets: defined by chapter 6 of the specification.
- *
- * \par Features not supported
- * - Link establishment procedure: defined by chapter 8 of the specification.
- * - Low power: defined by chapter 9 of the specification. 
- *
- * \par Implementation specific behaviour
- * - As Link establishment procedure is not supported following static link configuration parameters
- * are used:
- * + TX window size is 1.
- * + 16 bit CCITT-CRC must be used.
- * + Out of frame software flow control not supported.
- * + Parameters specific for resending reliable packets are compile time configurable (clarifed 
- * later in this document).
- * + Acknowledgement packet transmissions are not timeout driven , meaning they are delivered for 
- * transmission within same context which the corresponding application packet was received. 
- *
- * \par Implementation specific limitations
- * Current implementation has the following limitations which will have impact to system wide 
- * behaviour:
- * - Delayed acknowledgement scheduling not implemented: 
- * There exists a possibility that acknowledgement TX packet and application TX packet will collide 
- * in the TX pipeline having the end result that acknowledgement packet will be excluded from the TX 
- * pipeline which will trigger the retransmission algorithm within the peer protocol entity.
- * - Delayed retransmission scheduling not implemented:  
- * There exists a possibility that retransmitted application TX packet and acknowledgement TX packet
- * will collide in the TX pipeline having the end result that retransmitted application TX packet 
- * will be excluded from the TX pipeline.
- * - Processing of the acknowledgement number from RX application packets:
- * Acknowledgement number is not processed from the RX application packets having the end result 
- * that unnecessary application packet retransmissions can occur.
- *
- * The application TX packet processing flow is illustrated by the statemachine below. 
- *
- * @image html hci_transport_tx_sm.png "TX - application packet statemachine"
- *
- * \par Component specific configuration options
- *
- * The following compile time configuration options are available, and used to configure the 
- * application TX packet retransmission interval, in order to suite various application specific 
- * implementations:
- * - MAC_PACKET_SIZE_IN_BITS Maximum size of a single application packet in bits. 
- * - USED_BAUD_RATE Used uart baudrate. 
- *
- * The following compile time configuration option is available to configure module specific 
- * behaviour:
- * - MAX_RETRY_COUNT Max retransmission retry count for applicaton packets.
