Mysensor gateway UNO shield W5100

  • Hi! can someone help me please

    i have a problem.
    when i try to contact the gateway in domoticz i get the folowing message:

    2017-08-21 21:01:15.700 TCP: Reconnecting...
    2017-08-21 21:01:16.700 MySensors: connected to:
    2017-08-21 21:01:25.701 MySensors: Connection reset!
    2017-08-21 21:01:25.701 TCP: Reconnecting in 30 seconds...

    i use the folowing sketch:


    • 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.

    • 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 MY_DEFAULT_xxx_LED_PIN in the sketch below
      • 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 for wiring instructions.

    when i use the serial monitor in arduino app i get:

    0;255;3;0;9;TSM:INIT:TSP OK

    0;255;3;0;9;MCO:REG:NOT NEEDED
    0;255;3;0;9;MCO:BGN:INIT OK,TSP=1
    0;255;3;0;9;Eth: connect

    what do i do wrong?

  • Mod

    @bobbybobbybobby nothing wrong except that the latest Arduino boards are broken. See

    (Most likely problem at least)

    Arduino AVR Boards was at version 1.6.19. which did not work. I downgraded to 1.6.11

  • @mfalkvidd

    Great!! it works thanks for the fast reply

  • Mod

    there is 1.6.20 out... you could give it a shot, maybe they fixed something 😄
