Bebop 2 serial port

Hi everyone!
I will work with bebop 2 and ArduCopter.
I intend to use the UART serial port (or USB port) to connect a Bluetooth module for some communication. There are some guide to help me configure the port? Do you have some tips for me?

There isn’t a spare uart iirc. You could repurpose the USB port, but it would be a bit of hacking around in the Linux kernel.
You’re probably better off sticking with the onboard wifi.
