Ble library on esp32 is increasing flash usage of 60%

Hi community…

I am working with esp32 arduino framework (for sure platformio)
I am working on ble functionality for updating the fw via ble…
I made this function …

The issue is when I call the first line

BLEDevice::init(“ESP32 OTA”);

The flash usage is increasing of 60% …
I don’t think this is normal…

The class and routines are defined in BLEDevice.cpp…

Did you experience something similar?

Please let me know

Thanks
