Fieldbee recever on agopen

hi i am tring to get my fieldbee l2 reciever to work on AOG but with no succes. what is the correct way to add a gps reciever over a wifi hotspot on AOG? i could not find it in the divicemanager or via the ntrip ip adress. Or do i have to get an rtk reciever? is it than still posible to use the L2 basestation from fieldbee? Thanks i am new to all this so tanks for the info.
