Detailed Description

BT Core Spec v5.2: Vol 3, Part F ATT: 3.4.3.4 ATT_FIND_BY_TYPE_VALUE_RSP.

FIND_BY_TYPE_VALUE_RSP

Contains a list of elements, each comprised of { att_handle_start, group_end_handle } pair. The handles are comprised of two octets, i.e. uint16_t, hence one element is of size 4 octets.

 element := { uint16_t handle_start, uint16_t handle_end }

Used in:
