763 Listen and detect an external reader. Determine the best location
767 Inside the ListenReaderField() function, there is two mode.
768 By default, when you call the function, you will enter mode 1.
769 If you press the PM3 button one time, you will enter mode 2.
770 If you press the PM3 button a second time, you will exit the function.
772 DESCRIPTION OF MODE 1:
773 This mode just listens for an external reader field and lights up green
774 for HF and/or red for LF. This is the original mode of the detectreader
777 DESCRIPTION OF MODE 2:
778 This mode will visually represent, using the LEDs, the actual strength of the
779 current compared to the maximum current detected. Basically, once you know
780 what kind of external reader is present, it will help you spot the best location to place
781 your antenna. You will probably not get some good results if there is a LF and a HF reader
782 at the same place! :-)
