Can't find parameter BCN_TYPE with Copter 4.1

ArduCopter

In order to use Nooploop, I’ve download the latest copter 4.1 from https://firmware.ardupilot.org/Copter/latest/fmuv2/
But I still cannot find parameters about BCN_TYPE.
I was using Nooploop according to the tutor at https://ardupilot.org/copter/docs/common-nooploop.html
Is there anything wrong with this tutor?

fmuv2 is feature limited. Beacon is apparently one of those features. What Flight Controller?

pixhawk 2, I think. Do I need to use a higher version of pixhawk? Or where can I use the beacon features? THX

I don’t know what a Pixhawk 2 is but if it has 2mb flash then flash it with the Pixhawk1 target not fmuv2
