Dear NXP team:
We had integrated NFC library for "aNfcRdLib_SDK_Production_v2.9" into our MCU platform. We use the T4T application in out product. We discover some mobile phone can't get the T4T tag information from MCU. Besides, we installed the NFC tool in the mobile phone that it also can't get the T4T tag.
We try and analyze the issue that log shows on below.
log:
ActP4mC F06
ActP4mC F06
ActP4mC F06
Source code:
case PHAPP_T4T_CARD_EMU_ACTPALMC:
/* Validate RATS and send ATS */
CHECK_INPROCESS_FCT(status, phpalI14443p4mC_Activate(ppalI14443p4mC,
pDiscLoop->sTargetParams.pRxBuffer, (uint8)pDiscLoop->sTargetParams.wRxBufferLen,
aAtsRes, wAtsLengthVar));
DEBUG_PRINTF("ActP4mC %03X\n\r",status);
if((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
{
if(status == (PH_COMP_PAL_I14443P4MC | PH_ERR_INVALID_PARAMETER))
{
/* Invalid ATS */
ERROR_CRITICAL("ATS configured is invalid...\n");
break;
}
else if(status != (PH_COMP_PAL_I14443P4MC | PH_ERR_PROTOCOL_ERROR))
{
DEBUG_ERROR_PRINT(status);
}
else
{
/* Invalid RATS: Set to SLEEP_AF state if needed. */
}
}
How can we solve this issue?
