Ethernet gateway not willing to accept IP number



  • Dear all,
    I tried to use an ethernet gateway, following exactly the instructions here:
    https://www.mysensors.org/build/ethernet_gateway

    and using the WizNET (W5100) Ethernet module.

    I got the followinf messages from the arduino monitor:
    0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)
    0;255;3;0;9;TSM:INIT
    0;255;3;0;9;TSM:RADIO:OK
    0;255;3;0;9;TSM:GW MODE
    0;255;3;0;9;TSM:READY
    IP: 255.255.255.255
    0;255;3;0;9;No registration required
    0;255;3;0;9;Init complete, id=0, parent=0, distance=0, registration=1
    0;255;3;0;9;TSP:SANCHK:OK
    0;255;3;0;9;TSP:SANCHK:OK
    I used the code provided in the mysensors package (2.0) from the arduino program, where it specifies as IP address
    #define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 97

    I cannot find this gateway with my controller - not at 192.168.1.97 nor at 255.255.255.255
    Can anyone explain me why?
    Thanks a lot

    @Maurizio-Collu could you describe what do you do when you try to find the controller, and what happens?

    Is the ip address define line before the MySensors include?
    Is the ip address in the same adress range as your local network?

    255.255.255.255 is a broadcast address. You will probably not get a useful reply from there.

    Yes, it is defined before the MySensors include
    And yes, it is defined in the same address range

    Looks like you've confused the gateway with the controller. The gateway is defined to use 192.168.1.66.

    See https://www.mysensors.org/about/network for details on which component does what.



  • Thanks @mfalkvidd
    I'm not sure I understood your observation - probably I am missing something quite basic.

    I have a RasPi with Home Assistant installed (controller), with IP address 192.168.1.97, and I have connected to this RasPi an Arduino with the radio module - this is my serial controller.

    I would like to use also an ethernet gateway (in home assistant you can have more than one fateway), to receive signals of sensors in some remote rooms, and therefore I am using a W5100, NRF24L01, and an arduino (nano). I am asking through the code that this should have the IP address 192.168.1.66.

    What is wrong with this setup?


  • Mod

    @Maurizio-Collu I don't see anything wrong with that. You're the one saying something is wrong :-)

    Could you describe what you do when you try to find the W5100 gateway, what you expected to happen when you tried that, and what you experienced instead?
