Gateway Uno R3 + W5100 Ethernet Shield for Uno not working.



  • Hya,

    My network:

    192.168.80.1 -> 0.0.0.0 (gateway)
    192.168.80.4 (dns, dhcp)

    192.168.80.20 -> mysensors gateway

    not plugged the radio yet.

    after assembling the pack Uno R3 + W5100 Ethernet Shield for Uno, i flashed the following sketch:

    Upload to Uno R3 was successful, and plunging to the ethernet switch, only green led on the RJ45 lights, arp does not shows the mac address defined and ip defined does not pings.

    May i ask for help in order to solve?

    Thx in advance.

    Welcome to the forum @pw44

    If you don't want to connect the radio, you'll need to disable the use of the radio like this:

    //#define MY_RADIO_RF24
    

    Otherwise, MySensors will be unable to initialize the radio and will therefore not proceed.

    The debug log will give you more details. If you haven't already, see https://forum.mysensors.org/topic/666/read-this-first-it-could-save-you-a-lot-of-time/ for the most common problems and how to troubleshoot them.



  • @mfalkvidd

    Thank you for answering, and helping to solve. Having the radio module plugged, it worked.

    How to define it as a dhcp client instead of setting a fixed ip address, having only the mac address defined?

    Thx in advance!


  • Mod

    @pw44 comment out this part

    // Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
    #define MY_IP_ADDRESS 192,168,80,20
    


  • @mfalkvidd

    Thx, man!

    and to set the hostname? tried MY_HOSTNAME "MySensorsGW" , but no luck 😞


  • Mod

    @pw44 what type of hostname are you referring to?


  • Mod

    To expand, there are two types of hostnames often used: a mDNS hostname and a hostname option in the DHCP request.

    The reason MY_HOSTNAME doesn't have any effect is that MY_HOSTNAME is only supported by ESP8266 and ESP32. I'll amend the documentation to include that information.

    Some additional info: https://forum.arduino.cc/index.php?topic=622543.0



  • @mfalkvidd , thank you.

    no problem, host name can be assined by dhcp.

    problem is that commenting out the ip address, letting dhcp take care produces:

    $ arp
    Address HWtype HWaddress Flags Mask Iface
    192.168.80.115 (incomplete) enp2s0

    @pw44 what type of hostname are you referring to?
    hostname to identify itself

    @pw44 which machine are you running the arp command on? The router?
    Is 192.168.80.115 the IP the router assigned to the MySensors gateway?

    my server (dnsmasq, dhcp server) - 192.168.80.4
    adsl + router - 192.168.80.1

    mysensor gateway - 192.168.80.115 assigned by 192.168.80.4 (dhcp server)

    with fixed ip address it worked, but i guess maybe udp is not active at mysensors gateway.


  • Mod

    @pw44 the dhcp communication uses udp of course, but after that the MySensors gateway will use tcp unless MY_USE_UDP is defined.

    The gateway doesn't respond to icmp ping?

    Next step would be to check the gateway's debug log.

    if MY_USER_UDP is commented out, i understand that no UPD is enabled from start, correct?

    enabling MY_USER_UDP requires #define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 254
    and #define MY_CONTROLLER_URL_ADDRESS "my.controller.org"

    by enabling fixed ip, none of both is required, which is something not very clear for me.


  • Mod

    @pw44 which controller are you using? Why do you want to use udp for the connection to the controller?



  • @mfalkvidd
    no controller yet. i need to make the gateway at least be recognized by the network, either way.

    udp, for dhcp.


  • Mod

    @pw44 yes the MySensors gateway will of course use udp for dhcp. You don't need to do anything special to enable udp for dhcp.

    there must be something i'm not being able to figure out....

    dhcp served by dnsmasq. all other devices work without problem.


  • Mod

    @pw44 the log shows that the gateway is unable to initialize the nrf24 radio module. This prevents the gateway code from reaching the dhcp section.

    Double-check the nrf24 wiring. If you can, replace the radio module. If that doesn't help, post detailed photos of the wiring and we'll try to spot what could be wrong.


  • Mod

    Also, are you sure the w5100 shield you are using is capable of managing the SPI_EN signal?



  • these are the real photos of the setup.

    wire codes are the same as the build instructions 😉

    managing the SPI_EN signal? tried with and without, no changes.

  • Mod

    @pw44 you seem to have the same w5100 shield as i have. Try removing the sd card.
    If that doesn't work, try my fix here : https://forum.mysensors.org/topic/9732/arduino-uno-with-ethernet-shield-w5100-not-working/10



  • @Yveaux
    Thanks for the reply, removing the sd card or applying your fix did not change the problem.


  • Mod

    @pw44 why are spi clk/miso/mosi connected to A0.. 2 ¿




  • Mod

    @pw44 said in Gateway Uno R3 + W5100 Ethernet Shield for Uno not working.:

    as described in https://www.mysensors.org/build/ethernet_gateway

    Yes, but the sketch just below it has

    //#define MY_W5100_SPI_EN 4
    

    You actually have enabled this line, which causes the arduino to use hardware spi. And hardware spi uses different pins for clk/miso/mosi.
    You wired for software spi, so comment that line as in the example.



  • @Yveaux

    thanks man, you're right. commenting out

    //#define MY_W5100_SPI_EN 4
    

    solved it.

    just another question: does the 3.3v line from Uno R# enough power to handle the RF24 radio?

    Thx in advance!



  • @Yveaux and regardin IRQ from RF24, is it necessary to connect to pin2 of UNO R3?


  • Mod

    @pw44 no

    The IRQ pin is only required to be connected if the MY_RX_MESSAGE_BUFFER_FEATURE is defined in the sketch. Using this feature is recommended for high traffic nodes or gateways. Enabling it will result in better throughput but will require some additional memory to keep the message in memory before processing.

    More information: https://www.mysensors.org/build/connect_radio and MY_RX_MESSAGE_BUFFER_FEATURE



  • @mfalkvidd
    thank for the answer.

    i guess the UNO R3 is capable to do it, so, i tried

    #define MY_RX_MESSAGE_BUFFER_FEATURE
    #define MY_RF24_IRQ_PIN 3
    

    and got the following error:

    #error RF24 IRQ usage cannot be used with Soft SPI
    

    Any hint? The idea is having something like 80 nodes when all is done.

    Thx


  • Mod

    @pw44 unless your nodes send very frequently, you probably don’t need irq.

    If you need irq, you’ll need to use hardware spi.

    Ok, but just in case, how to use the hardware spi in this configurartion (sorry if it seams stupid, but i'm just a very beginner on this).

    Thx for the understanding and also for educating me,.


  • Mod

    @pw44 I don’t think anyone has managed to make the w5100 work on the same spi as nrf24.



  • @mfalkvidd

    ok, i was curious as i didn't find how to.

    Anyway, is it possible to have the "RF24 IRQ" used as soft?


  • Mod

    @pw44 no, mysensors doesn't need it for soft spi and won't use it
