Answer 1

parsed the json with three for loops, so my success function goes:-

mapResponse: function (data) {
  var dummy = data.detail.response;
  for(var i = 0;i < dummy.length; ++i) {
    for (var x in dummy[i]) {
      for (var t = 0; t < dummy[i][x].length; t++) {
        console.log(dummy[i][x][t].serialNo);
        console.log(dummy[i][x][t].status);
        console.log(dummy[i][x][t].firmwareStatus);
      }
    }
  }
}

Le me know for any simpler solution
