With regards to the amplitude and phase values, I see that these values are returned after the call to aatMeasure() in st25r3916_aat.c. The amplitude and phase values are returned as integers while the Discovery GUI returns the values as decimal numb...

Hi Ulysses,We have a custom antenna board for a reader board using ST25R3916. Since we can't hook up the custom antenna board to the Discovery GUI, my board bring-up FW will do the antenna tuning. We will save the AAT values resulting from that tunin...
