    Hello,

    I'm a bit confused.

    I got the following scenarios inside my network.

    First thing I found: NACK:50.6 (aswell as 2 mssg with OK) on my node, but my gateway tells me: "sure, I see it, cool bananas!"

    Node:

    TSF:MSG:SEND,1-1-0-0,s=255,c=3,t=0,pt=1,l=1,sg=0,ft=3,st=OK:88
    TSF:MSG:SEND,1-1-0-0,s=1,c=1,t=0,pt=7,l=5,sg=0,ft=0,st=OK:20.5
    !TSF:MSG:SEND,1-1-0-0,s=0,c=1,t=1,pt=7,l=5,sg=0,ft=0,st=NACK:50.6
    

    Gateway:

    0;255;3;0;9;TSP:MSG:READ 1-1-0 s=255,c=3,t=0,pt=1,l=1,sg=0:88
    0;255;3;0;9;TSP:MSG:READ 1-1-0 s=1,c=1,t=0,pt=7,l=5,sg=0:20.5
    0;255;3;0;9;TSP:MSG:READ 1-1-0 s=0,c=1,t=1,pt=7,l=5,sg=0:50.6
    

    A minute later I get the following:
    The Node tells me NACK:100 , NACK:50.3 and OK:20.5
    But my gateway now says, well srry buddy, the OK:20.5 didnt arrive.

    So only the OK mssg didnt come through.

    Node:

    !TSF:MSG:SEND,1-1-0-0,s=255,c=3,t=0,pt=1,l=1,sg=0,ft=1,st=NACK:100
    TSF:MSG:SEND,1-1-0-0,s=1,c=1,t=0,pt=7,l=5,sg=0,ft=2,st=OK:20.5
    !TSF:MSG:SEND,1-1-0-0,s=0,c=1,t=1,pt=7,l=5,sg=0,ft=0,st=NACK:50.3
    

    Gateway:

    0;255;3;0;9;TSP:MSG:READ 1-1-0 s=255,c=3,t=0,pt=1,l=1,sg=0:100
    0;255;3;0;9;TSP:MSG:READ 1-1-0 s=0,c=1,t=1,pt=7,l=5,sg=0:50.3
    

    Both have a RFM69.
    Gateway on ESP8266 -> 2.0.0 (2.1.0/2.1.1 made it reboot)
    node -> ms 2.1.0

    What should be my best guess? The gateway got trouble receiving or the node messes up the sending/receiving part?

    Thnx!

      Did you try to put them just a couple of meters away from each other? Just to exclude any range problem.

          1-2 meters is the right distance to exclude range problem. Then also power issues could cause messages to be lost.

            oke,
            well will look into the lost mssg.
            But my biggest question might be, why the node thinks they are NACK, but my gate tells me their fine?

              Could you post part of the code where you send those messages? do you send the node to sleep?

                @Omemanti Because the node can't receive the ack message so it assumes it's lost: could the the gateway didn't receive it or the node itself couldn't receive the ack from gateway. It could me many reasons, so you need to address it one by one until you find it 😀

                  mjah, ofcourse,
                  Well I'll build me some more of these, see If the same things happen with some other nodes.

                  thnx for the help so far!

                    After some time off I made more nodes. but somehow they all give me NACK's. (also changed the gateway, antennas and added more caps.)

                    The strange thing still is that even if I get NACK's the gateway seems the handle them..

                    Should I just accept this? Or am I missing something?

                    I should add that booting up takes a couple of tries, but after a minute of the folling it pulls through and starts the previous shenanigans.

                      it seems as the node can't receive correctly or the gw is not sending correctly. How far are they? If you put them a couple of meters apart do you see any change?

                        @gohan said in Help: Some explanation requested regarding NACK:

                        f meters apart do you see any change?

                        The node gateway is in the room below me (wooden floors) about 2 to 3 meters from my node.

                          Funny Part still is, that once the connection is made, everything also if produced with a NACK is received by the controller. thats what im curious about. If I get errors, why does the controllers receive them without bottering.

                            As I said, the GW is receiving the packet correctly but then the node doesn't get a good response so it throws a NACK. You could try and put them in same room and see if gets better or change channel just to avoid a possible interference

                              How can I change the channel? Can you point me in the right direction.?

                                Go in myconfig.h and search for "channel", you should find it in the nrf24 section, change the default channel there and recompile all your nodes and gateway

                                    Of course not. What version of rfm69 and frequency are you using? Are you sure you got the antenna of the right size?

                                      Rfm69w 868mhz , springcoil antenna from ebay.
                                      will test a long single wire right away.
