hi,paweljasinski: Speed value must be one of these constants: 9600 (default), 19200, 38400, 57600, 115200, 230400 or 460800.", uiPortSpeed); It's in the file “uart.c”. But 115200 is the PN532's default...

Please refer to the diagram:  To be sure that the baud rate-"Real HSU Freq" error is not greater than 4%:  [PN532 User Manual V0.2.pdf](https://github.com/nfc-tools/libnfc/files/14584891/PN532.User.Manual.V0.2.pdf) [PN532_C1.pdf](https://github.com/nfc-tools/libnfc/files/14584892/PN532_C1.pdf)

Poll the command "SAMConfiguration" at different baud rates before communication, such as: 55 55 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FF 03...

大佬，我目前在用MCU模拟PN532，HardNested使用MifareOne Tool能正常使用。 用这里的release版本，出现的现象和楼主一样。 大佬有计划修正吗？
