Trying to build a ethernet gateway but cant set an ip address



  • I have been running a serial gateway for quite a few years now but i have just built a ethernet gateway and am trying to get it up and running.....
    Here is the output from the monitor.
    MCO:BGN:INIT GW,CP=RNNGA---,FQ=16,REL=255,VER=2.3.2

    I cant seem to set an ip address, it keeps giving a random one each time i restart it. Any ideas?


  • Mod

    @JCH could you share how you try to set the ip address?

    This is how setting a static ip address is described on the build page:

    // Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
    #define MY_IP_ADDRESS 192,168,178,66
    


  • Here is my gateway code

    // Enable debug prints to serial monitor
    #define MY_DEBUG
    
    // Enable and select radio type attached
    #define MY_RADIO_RF24
    //#define MY_RADIO_NRF5_ESB
    //#define MY_RADIO_RFM69
    //#define MY_RADIO_RFM95
    
    // Enable gateway ethernet module type
    #define MY_GATEWAY_W5100
    
    // W5100 Ethernet module SPI enable (optional if using a shield/module that manages SPI_EN signal)
    //#define MY_W5100_SPI_EN 4
    
    // Enable Soft SPI for NRF radio (note different radio wiring is required)
    // The W5100 ethernet module seems to have a hard time co-operate with
    // radio on the same spi bus.
    #if !defined(MY_W5100_SPI_EN) && !defined(ARDUINO_ARCH_SAMD)
    #define MY_SOFTSPI
    #define MY_SOFT_SPI_SCK_PIN 14
    #define MY_SOFT_SPI_MISO_PIN 16
    #define MY_SOFT_SPI_MOSI_PIN 15
    #endif

    #endif
    
    // Enable UDP communication
    //#define MY_USE_UDP  // If using UDP you need to set MY_CONTROLLER_IP_ADDRESS or MY_CONTROLLER_URL_ADDRESS below
    
    // Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
    #define MY_IP_ADDRESS 192,168,1,6
    
    // If using static ip you can define Gateway and Subnet address as well
    #define MY_IP_GATEWAY_ADDRESS 192,168,1,1

    // Renewal period if using DHCP
    //#define MY_IP_RENEWAL_INTERVAL 60000
    
    // The port to keep open on node server mode / or port to contact in client mode
    #define MY_PORT 5003
    
    // Controller ip address. Enables client mode (default is "server" mode).
    // Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.
    //#define MY_CONTROLLER_IP_ADDRESS 192, 168, 1, 5
    //#define MY_CONTROLLER_URL_ADDRESS "my.controller.org"
    
    // The MAC address can be anything you want but should be unique on your network.
    // Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use.
    // Note that most of the Arduino examples use  "DEAD BEEF FEED" for the MAC address.
    #define MY_MAC_ADDRESS 0xDE,0xAD,0xBE,0xEF,0xFE,0xED
    
    
    // Enable inclusion mode

    @JCH looks similar to https://forum.mysensors.org/topic/9871/ethernet-w5100-gateway-ip-problem/

    How much ram on the Arduino is available after compiling the sketch?



  • How do i find that out? Is it this below?

    Sketch uses 24032 bytes (78%) of program storage space. Maximum is 30720 bytes.
    Global variables use 964 bytes (47%) of dynamic memory, leaving 1084 bytes for local variables. Maximum is 2048 bytes.


  • Mod

    @JCH yes exactly.
    Looks there is plenty of dynamic memory left, so it might not be related to the thread I linked 😞
