| - | In order to test the functionality of the ESP and the correct interconnection of the components from software, I have used test_espmodule.ino [5], which is attached at the end of this page. It is very useful as it uses AT basic commands and there is a transparent view of the status of the ESP. It is also very simple to update. | + | In order to test the functionality of the ESP and the correct interconnection of the components from software, I have used test_espmodule.ino [9], which is attached at the end of this page.
