@PilnyTomas please check my comments (typo and format issues), example is working great! Thank for the PR. After fixes it will be ready to merge.

I see that originally the method returns std::string, but please change it to Arduino String instead.

up in the includes, you need to change #include <string> to #include "Arduino.h"

It was not easy or obvious how to retrieve a MAC address of a local BT device.
There is an IDF function
esp_bt_dev_get_addresswhich accomplishes that and is used in this solution.However, there was no
BluetoothSerialmethod that would facilitate this.This PR adds three new methods, slightly extends the
BTAddress::toString, and adds a new exampleGetLocalMACwhich demonstrates the usage of the new additions.
