What is the expected behaviour of the FAST_WRITE command whilst in the AUTHENTICATED state?
The NT3H2111 datasheet doesn't make it very clear - from experimentation it appears I can do a FAST_WRITE to write the entire SRAM in this state but then the device appears to transition out of AUTHENTICATED as I can no longer read/write of protected memory until I issue a PWD_AUTH again.
The data sheet isn't totally clear.
Thanks!
Hi @aledh
Hope you are doing great, would it be possible that you share a command log between the reader and the NTAG I2C ? so I can see what might be happening and if something is being sent incorrectly ?
