 # 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.
