Please don’t post text as images. (See How do I format my forum post? to help posting code.)

LPP_APP_PORT is unrelated to LORAWAN_APP_PORT that you showed in an earlier post. (The first is just one of the many details that, in my opinion, cause unneeded overhead in the Cayenne LPP protocol. But that’s unrelated to your problems.)
