Bluetooth Core Specification v5.0, Vol 2, Part E, 7.8.12:
"The Supervision_Timeout parameter defines the link supervision timeout
for the connection. The Supervision_Timeout in milliseconds shall be larger
than (1 + Conn_Latency) * Conn_Interval_Max * 2, where Conn_Interval_Max is
given in milliseconds."
Let's remember that:
conn_interval is given in units N * 1.25 ms
sup_timeout is given in units N * 10 ms
sup_timeout_ms > (1 + latency) * (conn_interval_ms * 2)
yields:
sup_timeout_n * 10 > (1 + latency) * (conn_interval_n * 1.25 * 2)
yields:
sup_timeout_n * 10 > (1 + latency) * (conn_interval_n * 2.5)
yields:
sup_timeout_n * 4 > (1 + latency) * (conn_interval_n)

As per the spec, the station which disconnects the last dlc
should disconnect session also. In case if remote does not
do it we need to disconnect otherwise rfcomm will be connected
without any dlc. So this starts an idle timer to handle the
above scenario.
This also starts a disconnect timer to handle in case remote
does not respond to session disconnect request.

In order that host can continue a connection event by
enqueuing packets, the number of completed packets event
needs to be generated as soon it arrives on air. Hence, the
Controller now calls the radio_event_callback on every radio
Rx complete ISR.
The callback executes at the Radio ISR priority, take care
to only do as little as necessary in the callback, say, just
a semaphore give to wake up the hci_driver's thread.

splitted to logical record chunks if more than one record was found.
Every such portion represent unparsed SDP record prestripped from record
length. Each response record data passed to user starts from first raw
attributes data and the record response buffer's length tells exactly
about each record length. User UUID callback handler's return result
can drive delivery (dis)continuation of every such portion to the user.
