You have to put this line
console.log("count repetidos 2",countRepetidos); // value undefined
before the return function
return resolve(countRepetidos);
var countRepetidos;if(obj.data.list!={} && obj.data.list.length>0){
var aux = obj.data["list"];
countRepetidos=0;
for(var i=0;i<aux.length;i++){
Database.Probing.getMacAdress(aux[i]).then(function(data){
if(data.count>0){
countRepetidos++;
console.log("count repetidos 1",countRepetidos); // value 116
}
});
}
console.log("count repetidos 2",countRepetidos);
return resolve(countRepetidos);}
