A fork of the NimBLE stack restructured for compilation in the Ardruino IDE with a CPP library for use with ESP32. A fork of the NimBLE stack restructured for compilation in the Ardruino IDE with a CPP library for use with ESP32.
Why? Because the Bluedroid library is too bulky. This library **significantly** reduces resource usage and improves performance for ESP32 BLE applications as compared
with the bluedroid based library. The goal is to maintain, as much as reasonable, compatibility with the original
library but refactored to use the NimBLE stack. In addition, this library will be more actively developed and maintained
to provide improved capabilites and stability over the original.
Initial client code testing has resulted in code size reduction of ~115k and reduced ram consumption of ~37k. ## Resource use improvement:
Server code testing results from @beegee-toyo [from the project here](https://github.com/beegee-tokyo/ESP32WiFiBLE-NimBLE): ### (Original) BLE_client example comparison (Debug):
#### Arduino BLE Library
Sketch uses **1216377** bytes (58%) of program storage space.
Memory after connection: Free Heap: **171548**
### Memory usage (compilation output)
#### Arduino BLE library
```log
RAM: [== ] 17.7% (used 58156 bytes from 327680 bytes)
Flash: [======== ] 76.0% (used 1345630 bytes from 1769472 bytes)
```
#### NimBLE-Arduino library #### NimBLE-Arduino library

Flash: [======= ] 69.5% (used 911378 bytes from 1310720 bytes) ***
``` ### (Original) BLE_notify example comparison (Debug):
### Memory usage after **`setup()`** function #### Arduino BLE Library
#### Arduino BLE library Sketch uses **1208409** bytes (57%) of program storage space.
**`Internal Total heap 259104, internal Free Heap 91660`** Memory after connection: Free Heap: **173300**
#### NimBLE-Arduino library #### NimBLE-Arduino library
**`Internal Total heap 290288, internal Free Heap 182344`** Sketch uses **603432** bytes (28%) of program storage space.
Memory after connection: Free Heap: **269792**
**As shown: there is nearly a 50% reduction in flash use and approx. 100kB less ram consumed!**

This option determines for how long the local node advertises

specification limits this to 60 seconds, and implies that to

BLE_MESH_MSG_CACHE_SIZE:

Number of messages that are cached for the network. This description
prevent unnecessary decryption operations and unnecessary
relays. This option is similar to the replay protection list,
but has a different purpose.
value: 10
BLE_MESH_ADV_BUF_COUNT:
description: >
Number of advertising buffers available. This should be chosen
based on what kind of features the local node shoule have. E.g.
a relay will perform better the more buffers it has. Another
thing to consider is outgoing segmented messages. There must
be at least three more advertising buffers than the maximum
supported outgoing segment count (BT_MESH_TX_SEG_MAX).
value: 6
BLE_MESH_IVU_DIVIDER:
description: >
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 fulfil 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).
value: 4
BLE_MESH_TX_SEG_MSG_COUNT:
description: >
Maximum number of simultaneous outgoing multi-segment and/or
reliable messages.
value: 4
BLE_MESH_RX_SEG_MSG_COUNT:
description: >
Maximum number of simultaneous incoming multi-segment and/or
reliable messages.
value: 2
BLE_MESH_RX_SDU_MAX:
description: >
Maximum incoming Upper Transport Access PDU length. This
determines also how many segments incoming segmented messages
can have. Each segment can contain 12 bytes, so this value should
be set to a multiple of 12 to avoid wasted memory. The minimum
requirement is 2 segments (24 bytes) whereas the maximum supported
by the Mesh specification is 32 segments (384 bytes).
value: 72
BLE_MESH_TX_SEG_MAX:
description: >
Maximum number of segments supported for outgoing messages.
This value should typically be fine-tuned based on what
models the local node supports, i.e. what's the largest
message payload that the node needs to be able to send.
This value affects memory and call stack consumption, which
is why the default is lower than the maximum that the
specification would allow (32 segments).
The maximum outgoing SDU size is 12 times this number (out of
which 4 or 8 bytes is used for the Transport Layer MIC). For
example, 5 segments means the maximum SDU size is 60 bytes,
which leaves 56 bytes for application layer data using a
4-byte MIC and 52 bytes using an 8-byte MIC.
Be sure to specify a sufficient number of advertising buffers
when setting this option to a higher value. There must be at
least three more advertising buffers (BT_MESH_ADV_BUF_COUNT)
as there are outgoing segments.

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.
value: 128
BLE_MESH_RPL_STORE_TIMEOUT:

This value defines in seconds how soon the RPL gets written to

messages frequently it may make sense to have this set to a
large value, whereas if the RPL gets updated infrequently a
value as low as 0 (write immediately) may make sense. Note that
if the node operates a security sensitive use case, and there's
a risk of sudden power loss, it may be a security vulnerability
to set this value to anything else than 0 (a power loss before
writing to storage exposes the node to potential message
replay attacks).
