# *** UPDATE ***
**Breaking change:** Client and scan now use `std::vector` instead of `std::map` for storing the remote attribute database.
# *** UPDATES ***
**Breaking changes:**

> NimBLEClient::getServices(bool refresh = false)
> NimBLERemoteService::getCharacteristics(bool refresh = false)
> NimBLERemoteCharacteristic::getDecriptors(bool refresh = false)

These methods now take an optional (bool) parameter.
If true it will clear the respective vector and retrieve all the respective attributes from the peripheral.
If false(default) it will return the respective vector empty or otherwise with the currently stored attributes.
**NEW** on May 23, 2020
Client and scan now use `std::vector` instead of `std::map` for storing the remote attribute database.
This change will affect your application code if you use `NimBLEClient::getServices()` or `NimBLERemoteService::getCharacteristics()`
in your application as they now return a pointer to `std::vector` of the respective attributes.

These changes were necessary due to the amount of resources required to use `std::map`, it was not justifed by any benfit it provided.
It is expected that there will be minimal impact on most applications, if you need help adjusting your code please create an issue.

# esp-nimble-cpp
NimBLE CPP library for use with ESP32 that attempts to maintain compatibility with the @nkolban cpp_uitls API.
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.
**Testing shows a nearly 50% reduction in flash use and approx. 100kB less ram consumed vs the original!**
