h2zero c2ab790e1d [BREAKING] Refactor NimBLEAdvertised device.
* Construct the device with the parameters from the advertisement in the initialization list.
* Removed no longer needed methods; setAddress, setAdvType, setRSSI, setSetId, setPrimaryPhy, setSecondaryPhy, setPeriodicInterval.
* Removed `hasRSSI()` method, the RSSI is always reported so this is redundant.
* Replace setPayload with new method; `update` which will update the device info when new advertisement data is received.
* getPayload now returns `const std::vector<uint8_t>` instead of a pointer to internal memory.
* Added `begin` and `end` read-only iterators for convienience and use in range loops.
* Timestamp removed, if needed then the app should track the time in the callback.
* Consolidate some functions to use getPayloadByType.
* Add optional index parameter to getPayloadByType.
* Change payload indexing to use 0 as the first item.
* Code cleanup and apply const correctness.

esp-nimble-cpp

NimBLE CPP library for use with ESP32 that attempts to maintain compatibility with the nkolban cpp_uitls BLE API.

An Arduino version of this library, including NimBLE, can be found here.

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.

Testing shows a nearly 50% reduction in flash use and approx. 100kB less ram consumed vs the original!
Your results may vary

What is NimBLE?

NimBLE is a completely open source Bluetooth Low Energy stack produced by Apache.
It is more suited to resource constrained devices than bluedroid and has now been ported to the ESP32 by Espressif.

Installation

ESP-IDF v4.0+

Download as .zip and extract or clone into the components folder in your esp-idf project.

Run menuconfig, go to Component config->Bluetooth enable Bluetooth and in Bluetooth host NimBLE.
Configure settings in NimBLE Options.
#include "NimBLEDevice.h" in main.cpp.
Call NimBLEDevice::init(""); in app_main.

ESP-IDF v3.2 & v3.3

The NimBLE component does not come with these versions of IDF (now included in 3.3.2 and above).
A backport that works in these versions has been created and is available here.
Download or clone that repo into your project/components folder and run menuconfig. Configure settings in main menu -> NimBLE Options.

#include "NimBLEDevice.h" in main.cpp.
Call NimBLEDevice::init(""); in app_main.

Using

This library is intended to be compatible with the original ESP32 BLE functions and types with minor changes.

If you have not used the original Bluedroid library please refer to the New user guide.

If you are familiar with the original library, see: The migration guide for details about breaking changes and migration.

Also see Improvements_and_updates for information about non-breaking changes.

Full API documentation and class list can be found here.

Using with Arduino as an IDF component and CMake

When using this library along with Arduino and compiling with CMake you must add add_compile_definitions(ARDUINO_ARCH_ESP32=1)
in your project/CMakeLists.txt after the line include($ENV{IDF_PATH}/tools/cmake/project.cmake) to prevent Arduino from releasing BLE memory.
