3. Ethernet gateway with W5100

Ethernet gateway with W5100

  • Edoardo Macrì

    Hello,
    I recently decide to have some fun with Arduino and MySensors. I am not a programmer so I don know what exactly I'm doing.
    I bought on Ebay an Arduino Shield Compatible (not original, neither only for arduino uno r3) and to be sure an ethernet adapter too.
    The arduino shield have a Wiznet W5100 chip (which should be almost compatible with MySensors) and the etherent adapte have an ENC28J60 (which is supported but with some modificantions to the UIPE code).
    So, i put my shield on the arduino, in the w5100 gateway script enable the softspi and connected my nrf24... When I go to the serial console, it gave me DHCP Failture (once i got connected, on my router i reserved the ip for the arsuino specific mac address) and assigned a static ip of 192.168.1.35 (the one assigned by my router to the mac address). If I give the ip number in the console says that its connected successfully with that ip, but actually it isn't (if i go to my router it says that it isn't connected and the ip is free), even if i go to Domoticz it can't connect to the gateway, neither MyController (i hope it's spelled correctly).
    If i do the same for the ENC driver it works great, it even recognise my node (which is a RelayActuator on a nano) which when is connected through the w5100 doesn't show up in the Serial Console.

    I leave my codes Here so you can look and eventually tell me what is wrong:
    W5100 Code:

    /**
 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the ethernet link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * The GW code is designed for Arduino 328p / 16MHz.  ATmega168 does not have enough memory to run this program.
 *
 * LED purposes:
 * - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
 * - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or recieve crc error
 *
 * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

    Sorry for my bad english but it isn't my native language 😄

    You may need to comment out this line. It is preventing soft spi from being enabled

     // W5100 Ethernet module SPI enable (optional if using a shield/module that manages SPI_EN signal)
 #define MY_W5100_SPI_EN 4

    I've tried, moved SI SO SCK from the nrf to the respective analog pins but it won't worked, gave me the same problem

    Uh. I forgot to mention that the shield with the Ethernet library works perfectly, so it's isn't broken...

    @Edoardo-Macrì
    The example W5100 sketch from the arduino IDE should work without any modifications other than to set the ip address you want to use in the line

    #define MY_IP_ADDRESS

    You have made a few changes to the original sketch

    on my W5100 gateway the line below remains commented out

    // W5100 Ethernet module SPI enable (optional if using a shield/module that manages SPI_EN signal)
// #define MY_W5100_SPI_EN 4

    As does the line

    // Enable to UDP          
//#define MY_USE_UDP

    and if you are using a static address this line remains commented out as well

    // Renewal period if using DHCP
//#define MY_IP_RENEWAL_INTERVAL 60000

    Check your wiring it should be like below. Ignore the extra regulator if not using an amplified radio.

    Have you tried to ping the gateway ?

    maybe you could post the serial debug info as well, that might give a clue to the problem

    People had trouble with some versions of the Arduino IDE causing constant rebooting of the W5100 gateway. See this post

    Thanks, now it's working.. probably somethin in the DHCP string!

    This is the working code:
