I'm working on BLE project with espressif library. And It returns me founded BLE device.

std::string getManufacturerData();
std::string getName();
int         getRSSI();
BLEScan*    getScan();

When I want to print device name to serial port

BLEAdvertisedDevice founded_dev;
founded_dev=foundDevices.getDevice(0);
Serial.println("Name -> " + founded_dev.getName());

It gives me error like this

no matching function for call to 'HardwareSerial::println(std::__cxx11::basic_string<char>)'

So how can i convert to std:string to String in Arduino?

Don't. Instead just access the underlying C string:

Serial.print(F("Name -> "));
Serial.println(founded_dev.getName().c_str());
