The ACL Packet HCI Header contains the following information: +___________________________________________________+ |–Conn Handle (12 bits)–|–Pkt Boundary (2 bits)–| |----------------------—|----------------------—+ |–HCI_LLID(2 bits)---— |–Length(16 bits)– | +----------------------—|----------------------—+

Note:

1. Packet Boundary data indicates the following: +----------—+---------------—+---------------—+ | | Application to | Controller to | | | Controller | Application | +----------—|---------------—|---------------—| | 0x0u | Start of PDU | RESERVED | | 0x1u | Continuation PDU | RESERVED | | 0x2u | RESERVED | Start of PDU | | 0x3u | RESERVED | Continuation PDU | +----------—+---------------—+---------------—+
2. HCI_LLID data indicates the following: +----------—+---------------—| | 0x0u | Start of PDU | | 0x1u | Continuation PDU | | 0x2u | RESERVED | | 0x3u | RESERVED | ------------------------------—|
3. The value in the Length field does NOT include L2CAP header length (4 bytes).
