3 Segmentation and reassembly (SAR)
6 Segmentation and reassembly (SAR) provides a way of handling larger upper transport layer messages
25 The transport layer is able to transport up to 32 segments with its SAR mechanism, with a maximum
44 SAR does not impose extra overhead on the access layer payload per segment.
46 Segmentation and reassembly (SAR) Configuration models
49 With Bluetooth Mesh Protocol Specification version 1.1, it became possible to configure SAR
50 behavior, such as intervals, timers and retransmission counters, over a mesh network using SAR
56 The following SAR behavior applies regardless of the presence of a SAR Configuration Server on a

69 retransmissions timer. The initial value of the SAR Unicast Retransmissions timer depends on the
81 The initial value of the SAR Multicast Retransmissions timer is set to the multicast retransmissions
84 When the lower transport layer receives a message segment, it starts a SAR Discard timer. The
86 the segment belongs to. The initial value of the SAR Discard timer is the discard timeout value
87 indicated by the `SAR Discard Timeout`_ state.
89 SAR Acknowledgment timer holds the time before a Segment Acknowledgment message is sent for a
90 received segment. The initial value of the SAR Acknowledgment timer is calculated using the

104 * Multicast retransmissions count (see `SAR Multicast Retransmissions Count`_ state)
105 * Acknowledgment retransmissions count (see `SAR Acknowledgment Retransmissions Count`_ state)
108 `SAR Segments Threshold`_ state, Segment Acknowledgment messages are retransmitted using the value
109 of the `SAR Acknowledgment Retransmissions Count`_ state.
