The bluetooth port is not your mayfly.
I did this tutorial that could get you acquainted with the serial monitor: https://envirodiy.github.io/LearnEnviroDIY/01-ArduinoBasics/index.html
What’s uploaded on your Mayfly will determine the baud rate for the serial monitor. It looks like you haven’t uploaded anything yet, but there’s an existing sketch on the board. It’s getting power and charging (per the lights you see). The baud rate is probably slower than 57600.
