• Network disruption

  in ESP32 • 5 years, 2 months

  

  I tried this on a ESP8266 where it is working with a ip address. In the docs it states the parameter should be 'hostname', but when I try with a hostname I get an error:

  w.ping('google.com', (details) => { console.log(details) });
  Uncaught Error: Not a valid IP address.
  

  When I try this on a ESP32 I get:

  w=require('Wifi')
  =function () { [native code] }
  >w.ping('212.51.158.12', (details) => { console.log(details) });
  Uncaught Error: Function "ping" not found!
  

  Both ESP's are running espruino 2v00

  The ping method may work for me when it would be available on both platforms however it's somewhat tricky, because you can not decide how many pings are issued.

  Where could I find the source code of the 'net' Library?

  I am trying to make my things resistive to all sort of annoyances that can occour. Currently I am working on network disruptions, when the wireless router is still responsive but cannot connect to the internet. While I use websocket connections I saw that the websocket module wants to create a socket connection using net.connect(), but unfortunately I could not find any possibility to detect this condition in the documentation. I get just a message at the console:

  ERROR: Connect failed (err 113)
  Uncaught InternalError: Unable to create socket
  

  I don't know whether this is specific on the ESP32.

• Problem with watches on esp32

  in ESP32 • 5 years, 2 months

  

  I tried to use a watch on a esp32 where I got the following error:

  setWatch(function(st) { console.log(st.time) }, D4, {repeat: false, edge: 'falling', debounce: 10});
  WARNING: Unable to set watch. You may already have a watch on a pin with the same number (eg. A0 and B0),
  or this pin cannot be used with watch
  

  I also tried other pins which should work without luck. I am using esruino 2v00 on a esp32s chip. On espruino 2v01 i get the same message.

• Accessing the calling class instance method within the module

  in General • 5 years, 3 months

  

  I want to call a method of the calling class within a module. This worked fine in Version 2v00 of espruino. After updating to 2v01 I get an error with the same code.

  This is the calling program:

  class a {
    constructor() {
      this.mB = null;
    }
    
    init() {
      this.mB = new (require('http://192.168.88.117:8081/b.j­s'))(this);
      this.mB.perform();
    }
  
    say(text) {
      console.log(text);
    }
  }
  
  var x = new a();
  x.init();
  

  And this is the module:

  class b {
    constructor(a) {
      this.a = a;
    }
    
    perform() {
      console.log('class b called');
      this.a.say("I'm in b");
    }
  }
  exports = b;
  

  The output shows as follows:

  Error: Line 8: Unexpected reserved word in http://192.168.88.117:8081/b.js

  It seems that the parameter for the constructor is not passed anymore in 2v01
