You are not providing very much information - almost nothing at all. Here is a Bluetooth testbed - it might help you get started. I am always changing it so not everything will be working, but it should be enough to allow you to make contact with your ESP32 and exchange single characters. It is written for an HC-05 module using classic BT, not BLE. I think that the ESP32 supports both.
