This is in BeeStack. Most applications I saw use APSDE-Data.request, but there's also NLDE-Data.request. What advantages does APSDE has over NLDE in terms of data request, and vice versa? What would happen if I started to use NLDE instead of APSDE? I noticed that there's AF_DataRequest as well, and the book by Drew Gislason says that's all you need in order to send/receive data (page 112).
