478 Listen and detect an external reader. Determine the best location
482 Inside the ListenReaderField() function, there is two mode.
483 By default, when you call the function, you will enter mode 1.
484 If you press the PM3 button one time, you will enter mode 2.
485 If you press the PM3 button a second time, you will exit the function.
487 DESCRIPTION OF MODE 1:
488 This mode just listens for an external reader field and lights up green
489 for HF and/or red for LF. This is the original mode of the detectreader
492 DESCRIPTION OF MODE 2:
493 This mode will visually represent, using the LEDs, the actual strength of the
494 current compared to the maximum current detected. Basically, once you know
495 what kind of external reader is present, it will help you spot the best location to place
496 your antenna. You will probably not get some good results if there is a LF and a HF reader
497 at the same place! :-)
