455 Listen and detect an external reader. Determine the best location
459 Inside the ListenReaderField() function, there is two mode.
460 By default, when you call the function, you will enter mode 1.
461 If you press the PM3 button one time, you will enter mode 2.
462 If you press the PM3 button a second time, you will exit the function.
464 DESCRIPTION OF MODE 1:
465 This mode just listens for an external reader field and lights up green
466 for HF and/or red for LF. This is the original mode of the detectreader
469 DESCRIPTION OF MODE 2:
470 This mode will visually represent, using the LEDs, the actual strength of the
471 current compared to the maximum current detected. Basically, once you know
472 what kind of external reader is present, it will help you spot the best location to place
473 your antenna. You will probably not get some good results if there is a LF and a HF reader
474 at the same place! :-)
