In fact, a limited number here is fine too. The thing is, my can-j1939 stack is (BSD sockets alike) assigned a limited number of J1939 source addresses. Only those source addresses are allowed in outgoing packets (a bit like IP networks, and probably others) No, all 3 PGNs are sent by one sender(source)! --Wolfgang
