https://community.nxp.com/t5/NFC/About-RF-collision-avoidance/m-p/1721557#M10728 <P>Hello,</P><P>I'm using PN5190. I want to know about RF collision avoidance.<BR />The setting (PHHAL_HW_CONFIG_RFCA) can be set by phNfcLib_SetConfig().</P><P>Checking the NFC Reader Library, the default is PH_ON, which is set during initialization: phhalHw_Pn5190_Init() and phhalHw_Pn5190_DeInit().<BR />And in phacDiscLoop_Run, it sets PH_ON for NFC/ISO and PH_OFF for EMV.</P><P>[Question 1]<BR />If the default is changed to PH_OFF and PH_OFF is set for NFC/ISO in phacDiscLoop_Run,<BR />will there be any impact on some movements? Will it only not detect collision errors during carrier on?</P><P>[Question 2]<BR />The default setting is PH_ON, and it is only changed to PH_OFF for EMV.<BR />Is there any reason for changing EMV setting?</P><P>Thanks</P> Wed, 13 Sep 2023 02:42:39 GMT ttkk_01 2023-09-13T02:42:39Z https://community.nxp.com/t5/NFC/About-RF-collision-avoidance/m-p/1721557#M10728 <P>Hello,</P><P>I'm using PN5190.
