  So, sorry for the late answer.

  I tested some issues.

  I recommend you connect your WIZ550io's RDY pin to espruino's any GPIO pin and do ether.getIP() or ether.setIP() after its value turns to '1'

  I check the RDY pin, but after the value was '1', nothing changed. DHCP is still not working. At the moment, i'm not able to set a static ip address at this place (university network), but i will test it at home again.

  If it is, can you try connecting it to an LED instead and test it with digitalWrite(B2,1)? It's possible that your Espruino board has a bad connection.

  I test the B2 pin with a LED and it works well. So the connection is definitively ok.

  Well, i don't know how i get this module to getting work.

  Any other suggestions? Test issues?

  @all: thanks for your feedback... now, i'm back from italy and ready for further tests (fully recovered and relaxed) :-) I will give you feedback during this week. I hope the next tests are successfully.

  Ok, i had not much time for a extensive test. I just set up all pins and connection from the scratch and retry the main features again.

  (same network / router configuration like before)

  • DHCP still fail
    
  • eth.setIP({ "ip": "192.168.1.2", ... }) works after 2-3 function calls (very strange)
    
  • first eth.getIP() call returns very strange ip settings (e.g. { "ip": "3.192.168.1", ... })
    
  • ping from my Mac Book to the espruino works
    
  • http server 'hello work' doesn't
    
  • http request to my Mac Book apache doesn't work
    
    

  The result was the same like my first documentation. At the moment, I don't know what I'm doing wrong. After my holidays i give that another with new network and router configuration. Additionally a friend of mine will take a look at my configuration.

  I'll keep you up to date

  @user47955: which revision do you have?

  I'm suspicious of above result. In static IP mode, its IP address should be read correctly, but you couldn't do that.

  I hope we're not talking past each other. DHCP connection doesn't work. A static ip definition with eth.setIP({....}); works well. I can ping to the defined ip address. But the server application doesn't work. No response after running a page request or setup a simple http server.

  Well, i give this issue another try this weekend, but I guess I can not handle an oscilloscope :-) Nevertheless, I try my best to find a way for debugging.

  Hi,

  i guess the api has changed a little bit. You can see the change in the following commit:

  https://github.com/espruino/EspruinoDocs/commit/e1b6dd998d6d3a6d6d5466dcdcc5d4a70b8ecc4f
  

  Try: while (nrf.getDataPipe() !== undefined) {}

  I've just fired off an e-mail to WIZnet and we'll see if they can think of anything.

  @Gordon: do you have an update or feedback from wiznet?

  Here a little example. I clean and reduce a little bit the code. Some var definitions are not needed.

  /* Copyright (c) 2014 ToDo */
  /*
  Quick description ToDO
  */
  
  var C = {
    ADDRESS : 0x48    // description
  };
  
  /**
   * Description
  */
  function TMP102(_i2c) {
      this.i2c = _i2c;
  }
  
  /**
   * Description
  */
  TMP102.prototype.getTemperature = function() {
      var d = this.i2c.readFrom(C.ADDRESS, 2);
      return (((d[0] << 8) | d[1]) >> 4)*0.0625; 
  };
  
  /**
   * export
  */
  exports.connect = function (_i2c) {
      return new TMP102(_i2c);
  };

  It is really a good idea, to return an error message string instead of an error code? I guess thois could safe some memory and performance. What do you think?

  I don't know if this is a big issue for other people, but for me it's a part of user experience. On most project pages you can find in the header of the page the current version or a little eyecatcher. From this view, i guess it would be an improvment, to present the release much more prominent.

  And please, this issue has a low priority! Other things are much more important...
