How to make an AI character detect another AI character?

Hi, AI character can detect my character, but when I put it to detect another AI, it does not work.

you should provide more info. whats your setup like and what have you tried thus far? are you using pawn sensing or ai perception? any eqs involved? are you trying to make use of the team settings (not sure those ever got properly implemented in bp. im referring to the friendly hostile whatever setting).
