is fixed channels is a connection oriented channel..?


The fixed channel used for ATT information in heart rate profile is a connection oriented channel or connection less channel...?

  • Vol 3, Part A, Section 3 in the Bluetooth Core Specification:

    Channels may be connection-oriented or connectionless. Fixed channels other than the L2CAP connectionless channel (CID 0x0002) and the two L2CAP signaling channels (CIDs 0x0001 and 0x0005) are considered connection-oriented.

    Vol 3, Part G, Section 5.2.2 in the Bluetooth Core Specification contains the LE Channel Requirements. L2CAP fixed CID 0x0004 shall be used for the Attribute Protocol.
