![]() Is it the same method as reading the mapped SRAM ? in which we just need to read from the memory address. 0xF8, 0xF9, 0圎8, and 0圎9. Second packet send to NXP NTAG I2C 1K RF interface : 0x00, 0x00, 0x00, 0x00, CRC, then NO REPLY from NXP NTAG I2C 1K RF interface.įor read NXP NTAG Register (configuration and session) from RF interface: I have follow this procedure of writing to NXP NTAG I2C 1K RF interface, which is the following sequence:įirst packet send to NXP NTAG I2C 1K RF interface : 0xC2, 0xFF, CRC, then wait for ACK from NXP NTAG I2C 1K RF interface. There should have ACK send back but no reply from NXP NTAG I2C 1K RF interface. Failure occurred after send out first packet to NXP NTAG I2C 1K RF interface. Device A has return a timeout message to its host, which also meant that timeout while waiting for packet from NXP NTAG I2C 1K. ![]() ![]() However, instead of read it back after NXP NTAG I2C 1K is written (64 bytes) by its host, I write 64 bytes to the Mapped SRAM (0xF0) using device A. I have successfully write to SRAM of NXP NTAG I2C 1K and then read back using device A from NXP NTAG I2C 1K RF interface mapped SRAM address 0xF0. I am reading and then writing to NXP NTAG I2C 1K using another NFC device - Device A.ĭuring reading and writing, Pass Through is constantly ON and then RF wave is constantly emitted to NXP NTAG I2C 1K.
