Do I still need a Bluetooth Module if I have a NodeMCU ESP32?

Hey there.

I want to connect the Arduino with my Android app via bluetooth. As far as I concern, the NodeMCU ESP32 already has an in-built bluetooth. In that case, do I still need to purchase a Bluetooth Module to connect the app with Arduino?

Thank you.

ESP-32 alone can perform this task. No additional bluetooth module is needed.

I see. Thank you very much.
