This value defines in seconds how soon unsaved RPL entries

to a large number may lead to security vulnerabilities if a node
gets powered off before the timer is fired. When flash is used
as the persistent storage setting this value to a low number
may wear out flash sooner or later. However, if the RPL gets
updated infrequently a value as low as 0 (write immediately)
may make sense. Setting this value to -1 will disable this timer.
In this case, a user is responsible to store pending RPL entries
using @ref bt_mesh_rpl_pending_store. In the mean time, when
IV Index is updated, the outdated RPL entries will still be
stored by @ref BT_MESH_STORE_TIMEOUT. Finding the right balance
between this timeout and calling @ref bt_mesh_rpl_pending_store
may reduce a risk of security vulnerability and flash wear out.
Failure to store the RPL and becoming vulnerable after reboot

the message. This maximizes the utilization efficiency of
advertising sets, which is helpful for the sending of dense
relays. With CONFIG_BT_MESH_RELAY_RETRANSMIT_COUNT value
greater than zero, this can noticeably delay transmission of
local messages. When Friend feature is enabled and the node is

When the IV Update state enters Normal operation or IV Update
in Progress, we need to keep track of how many hours has passed
in the state, since the specification requires us to remain in
the state at least for 96 hours (Update in Progress has an
additional upper limit of 144 hours).
In order to fulfill the above requirement, even if the node might
be powered off once in a while, we need to store persistently
how many hours the node has been in the state. This doesn't
necessarily need to happen every hour (thanks to the flexible
duration range). The exact cadence will depend a lot on the
ways that the node will be used and what kind of power source it
has.
Since there is no single optimal answer, this configuration
option allows specifying a divider, i.e. how many intervals
the 96 hour minimum gets split into. After each interval the
duration that the node has been in the current state gets
stored to flash. E.g. the default value of 4 means that the
state is saved every 24 hours (96 / 4).

The maximum incoming SDU size is 12 times this number (out of
which 4 or 8 bytes is used for the Transport Layer MIC). For

int "Delay (in seconds) before storing anything persistently"
range 0 1000000
default 2
help
This value defines in seconds how soon any pending changes
are actually written into persistent storage (flash) after
a change occurs.
config BT_MESH_SEQ_STORE_RATE
int "How often the sequence number gets updated in storage"
range 0 1000000
default 128
help
This value defines how often the local sequence number gets
updated in persistent storage (i.e. flash). E.g. a value of 100
means that the sequence number will be stored to flash on every
100th increment. If the node sends messages very frequently a
higher value makes more sense, whereas if the node sends
infrequently a value as low as 0 (update storage for every
increment) can make sense. When the stack gets initialized it
will add this number to the last stored one, so that it starts
off with a value that's guaranteed to be larger than the last
one used before power off.

Use this option to enable debug logs for the Bluetooth
Mesh functionality.

This option forces the usage of the local identity address for
all advertising. This can be a help for debugging (analyzing
traces), however it should never be enabled for a production
build as it compromises the privacy of the device.
