How do I connect Arduino Nano 33 IoT to my phone using Bluetooth?

I am getting started with using the Nano 33 IoT board and want to connect it to my phone via Bluetooth. All I want to do is display the RSSI value of the connection between the phone and the board on the serial monitor.

I am trying to do this using the ArduinoBLE library with the board as the central device and my phone as a peripheral. How do I go about connecting them and displaying the RSSI value?

Thank you so much.

For the board side all you need are the examples that comes with the library, for the phone it depends on what type of app you want to use, a ready one like LightBlue which can display RSSI and much more, ot an app of your own which requires other skills and knowhow.
