Implement the Driver For Bluetooth Device

I have a HP mouse. Recently, I have been practicing implementing the device driver. Instead of using the hid-generic driver, I would like to use my customized driver for the Bluetooth device. I don't have any ideas about how to implement it in another way for this character device. My idea is kind of similar to my previous implementation on the USB driver by using the USB API instead of the hid-usb static driver. I am wondering if there is any API or subsystem category related to Bluetooth that I can use to implement a driver for the mouse. Or I am wondering if there are any better ideas or designs about this.
