home automation with arduino and android

Hello!

I try to get this to work with the 28J60 Ethernet Shield.

But i get error in the android APP "An error has accoured, check your internet connection. Is Arduino Alive?"
It all works, i get "my item" and i can controll the arduino output from the app.
The only problem seems to be with the JSON from the arduino to the android app. When i test in my web browser its look like this:

//arduinoIP/?out=5&status=0
-> {"status" : "0" , "out" : "5"}
//arduinoIP/?out=5&status=1
-> {"status" : "1" , "out" : "5"}

What can be wrong?

 if (strcmp(params, "?out=all") == 0)
  
         {
           e.print("{\"ip\" : \"192.168.0.15\", \"devices\" : [{ \"type\" : \"plug\", \"name\" : \"LAMPA\", \"out\" : \"");          
           e.print("5\"}");            
           e.print("]}");       
           e.respond();
          Serial.println("OUTALL!!");
        } 

 if (strcmp(params, "?out=5&status=0") == 0)
       { 
           digitalWrite(pinOutRelay, LOW);
             Serial.println("OUT LOW!!");
            e.print("{\"status\" : \"0\" , \"out\" : \"");
            e.print("5\"}");   
            e.respond();  
           Serial.println("LOW!!");   
      }

 if (strcmp(params, "?out=5&status=1") == 0)
     { 
           digitalWrite(pinOutRelay, HIGH);
           Serial.println("OUT HIGH!!");
           e.print("{\"status\" : \"1\" , \"out\" : \"");
           e.print("5\"}");    
           e.respond();
           Serial.println("HIGH!!"); 
     }

Edit: I found the error :slight_smile:
I had a old DomoticHome APP installed . It work perfect with the app from market.
