jksoft | 1:48f6e08a3ac2 | 18 | * |
jksoft | 1:48f6e08a3ac2 | 19 | * @brief HCI transport module implementation. |
jksoft | 1:48f6e08a3ac2 | 20 | * |
jksoft | 1:48f6e08a3ac2 | 21 | * This module implements certain specific features from the three-wire UART transport layer, |
jksoft | 1:48f6e08a3ac2 | 22 | * defined by the Bluetooth specification version 4.0 [Vol 4] part D. |
jksoft | 1:48f6e08a3ac2 | 23 | * |
jksoft | 1:48f6e08a3ac2 | 24 | * \par Features supported |
jksoft | 1:48f6e08a3ac2 | 25 | * - Transmission and reception of Vendor Specific HCI packet type application packets. |
jksoft | 1:48f6e08a3ac2 | 26 | * - Transmission and reception of reliable packets: defined by chapter 6 of the specification. |
jksoft | 1:48f6e08a3ac2 | 27 | * |
jksoft | 1:48f6e08a3ac2 | 28 | * \par Features not supported |
jksoft | 1:48f6e08a3ac2 | 29 | * - Link establishment procedure: defined by chapter 8 of the specification. |
jksoft | 1:48f6e08a3ac2 | 30 | * - Low power: defined by chapter 9 of the specification. |
jksoft | 1:48f6e08a3ac2 | 31 | * |
jksoft | 1:48f6e08a3ac2 | 32 | * \par Implementation specific behaviour |
jksoft | 1:48f6e08a3ac2 | 33 | * - As Link establishment procedure is not supported following static link configuration parameters |
jksoft | 1:48f6e08a3ac2 | 34 | * are used: |
jksoft | 1:48f6e08a3ac2 | 35 | * + TX window size is 1. |
jksoft | 1:48f6e08a3ac2 | 36 | * + 16 bit CCITT-CRC must be used. |
jksoft | 1:48f6e08a3ac2 | 37 | * + Out of frame software flow control not supported. |
jksoft | 1:48f6e08a3ac2 | 38 | * + Parameters specific for resending reliable packets are compile time configurable (clarifed |
jksoft | 1:48f6e08a3ac2 | 39 | * later in this document). |
jksoft | 1:48f6e08a3ac2 | 40 | * + Acknowledgement packet transmissions are not timeout driven , meaning they are delivered for |
jksoft | 1:48f6e08a3ac2 | 41 | * transmission within same context which the corresponding application packet was received. |
jksoft | 1:48f6e08a3ac2 | 42 | * |
jksoft | 1:48f6e08a3ac2 | 43 | * \par Implementation specific limitations |
jksoft | 1:48f6e08a3ac2 | 44 | * Current implementation has the following limitations which will have impact to system wide |
jksoft | 1:48f6e08a3ac2 | 45 | * behaviour: |
jksoft | 1:48f6e08a3ac2 | 46 | * - Delayed acknowledgement scheduling not implemented: |
jksoft | 1:48f6e08a3ac2 | 47 | * There exists a possibility that acknowledgement TX packet and application TX packet will collide |
jksoft | 1:48f6e08a3ac2 | 48 | * in the TX pipeline having the end result that acknowledgement packet will be excluded from the TX |
jksoft | 1:48f6e08a3ac2 | 49 | * pipeline which will trigger the retransmission algorithm within the peer protocol entity. |
jksoft | 1:48f6e08a3ac2 | 50 | * - Delayed retransmission scheduling not implemented: |
jksoft | 1:48f6e08a3ac2 | 51 | * There exists a possibility that retransmitted application TX packet and acknowledgement TX packet |
jksoft | 1:48f6e08a3ac2 | 52 | * will collide in the TX pipeline having the end result that retransmitted application TX packet |
jksoft | 1:48f6e08a3ac2 | 53 | * will be excluded from the TX pipeline. |
jksoft | 1:48f6e08a3ac2 | 54 | * - Processing of the acknowledgement number from RX application packets: |
jksoft | 1:48f6e08a3ac2 | 55 | * Acknowledgement number is not processed from the RX application packets having the end result |
jksoft | 1:48f6e08a3ac2 | 56 | * that unnecessary application packet retransmissions can occur. |
jksoft | 1:48f6e08a3ac2 | 57 | * |
jksoft | 1:48f6e08a3ac2 | 58 | * The application TX packet processing flow is illustrated by the statemachine below. |
jksoft | 1:48f6e08a3ac2 | 59 | * |
jksoft | 1:48f6e08a3ac2 | 60 | * @image html hci_transport_tx_sm.png "TX - application packet statemachine" |
jksoft | 1:48f6e08a3ac2 | 61 | * |
jksoft | 1:48f6e08a3ac2 | 62 | * \par Component specific configuration options |
jksoft | 1:48f6e08a3ac2 | 63 | * |
jksoft | 1:48f6e08a3ac2 | 64 | * The following compile time configuration options are available, and used to configure the |
jksoft | 1:48f6e08a3ac2 | 65 | * application TX packet retransmission interval, in order to suite various application specific |
jksoft | 1:48f6e08a3ac2 | 66 | * implementations: |
jksoft | 1:48f6e08a3ac2 | 67 | * - MAC_PACKET_SIZE_IN_BITS Maximum size of a single application packet in bits. |
jksoft | 1:48f6e08a3ac2 | 68 | * - USED_BAUD_RATE Used uart baudrate. |
jksoft | 1:48f6e08a3ac2 | 69 | * |
jksoft | 1:48f6e08a3ac2 | 70 | * The following compile time configuration option is available to configure module specific |
jksoft | 1:48f6e08a3ac2 | 71 | * behaviour: |
jksoft | 1:48f6e08a3ac2 | 72 | * - MAX_RETRY_COUNT Max retransmission retry count for applicaton packets. |
