Id_coisa = id of a key on my database, in the case only accepts "11"
Valor = any value between 0 and 255
Dvc = name of the device used to make the request, accepts any text
When the request is sent i receive "SEND OK", but nothing is registered in the database and there's no feedback of the page, in the case of invalid parameters it should return " ERRO" and if everything is OK, "SUCCESS"
