PN7160 stuck in wait for discovery

[phemidal]

Hi,

I work with the PN7160B1 on an STM32 microcontroller and try to run the RW example. If I start the example, the first runs works fine (tested with an android phone), but after 2 or 3 runs it stucks in the function 'NxpNci_WaitForDiscoveryNotification' in this line:

while(Answer != 0) NxpNci_WaitForReception(Answer, sizeof(Answer), &AnswerSize, TIMEOUT_100MS)

The PN7160 is supplied with 3.3V, so i changed the tvdd_conf to: '0x20, 0x02, 0x0F, 0x01, 0xA0, 0x0E, 0x0B, 0x11, 0x01, 0x01, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x10, 0x0C' (changed byte 7 and byte 9 otherwise i got RF_TXLDO_ERROR_NTF errors). The SPI speed is 5.25 MHz.

The complete log until it hangs:

If i define 'REMOVE_P2P_SUPPORT' the code works but does not detect correctly when the card is removed (prints 4-6 times the same text).

Can somebody help me to check if the config and the communication with the IC is correct?

[michael_d_1983]

i has this problem too, seems to be an copy paste error.

i think it should be:

while(AnswerSize != 0)

    NxpNci_WaitForReception(Answer, sizeof(Answer), &AnswerSize, TIMEOUT_100MS)
