Ethernet Gateway with Nano - Invalid message length, 0 (actual) != 7 (expected)



  • Hi Guys,
    back again with another problem; i m trying to build Ethernet gateway, it starts ok, gets ip but then it goes into some loop with this message on serial port:

     * The sensors forms a self healing radio network with optional repeaters. Each

     * network topology allowing messages to be routed to nodes.

     * REVISION HISTORY
     * Version 1.0 - Henrik EKblad

     *
     * 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 MY_DEFAULT_xxx_LED_PIN in the sketch below
     * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
     * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
     * - ERR (red) - fast blink on error during transmission error or receive crc error
     *
     * See http://www.mysensors.org/build/ethernet_gateway for wiring instructions.

    @pihome said in Ethernet Gateway with Nano - Invalid message length, 0 (actual) != 7 (expected):

    0;255;3;0;9;TSF:MSG:READ,0-0-0,s=0,c=0,t=0,pt=0,l=0,sg=0:
    0;255;3;0;9;!TSF:MSG:LEN,0!=7

    As you can see the gateway is only receiving zeroes, probably due to a radio communication problem.
    See this thread for some suggestions on how to solve it.



  • @Yveaux
    yes it looks like power issue, haven't fixed it yet but for future if some one stumbled upon this posts: gateway starts ok, but as soon as some message arrives gateway reset and controller lost connection with gateway (serial output below), i dont have inductor available to test suggested solution.
    PS: i have tried supplying power from separate source to W5100, changed cap on nrf from 10uf to 100uf but no luck.

    thank you for help, downgrading to the 1.16.11 version fixed the disconnection issue. now back to power problem, i have order inductors to test this but it need another 4 weeks 😞

    How to Change to version 1.116.11
    172pilot: "Tools, Board, and at the top of the list, choose board manager, click in the window for "Arduino AVR Boards" and it will give you a pull-down for 'version' in the bottom left. Choose your 1.16.11 version, and click install.."

  • Hi Guys,
    while troubleshooting Ethernet gateway, i discover my arduino nano voltage on different pin as i wasn't sure from where to feed power to W51000 module just decided to check voltage on these three different pins and to my surprise all three gives different values . i can not find any decent schematic to check reason for these different voltage. can some shed some light please... i always thought 5v is straight from usb connector without any regulator etc...

    voltage at USB connector 5.11v
    VIN Pin 4.33v
    5v Pin 4.76v


  • Mod

    @pihome according to the arduino nano schematic 5v is connected through a diode to vusb; you'll see the voltage drop.
    Vin is meant as input for the nano's voltage regulator. You should only feed power to it, not sink from it.



  • @Yveaux
    thank you for reply, found something similar for 5v, just in case some one stumble upon this.

    +5V	Output or Input	
    +5V Output (From On-board Regulator) or
    +5V (Input from External Power Supply
