# Overview
|
|
This is a C++ BLE library for the ESP32 that uses the NimBLE host stack instead of bluedroid.
|
|
The aim is to maintain, as much as reasonable, the original bluedroid C++ & Arduino BLE API by while adding new features
|
|
and making improvements in performance, resource use, and stability.
|
|
|
|
**Testing shows a nearly 50% reduction in flash use and approx. 100kB less ram consumed vs the original!**
|

# What is NimBLE?
|
|
NimBLE is a completely open source Bluetooth Low Energy stack produced by [Apache](https://github.com/apache/mynewt-nimble).
|
|
It is more suited to resource constrained devices than bluedroid and has now been ported to the ESP32 by Espressif.

# ESP-IDF Installation
|
|
## 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`.
|

# 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](New_user_guide.md).
|
|
|
|
If you are familiar with the original library, see: [The migration guide](Migration_guide.md) for details.
|
|
|
|
For more advanced usage see [Usage tips](Usage_tips.md) for more performance and optimization.
