Hello everyone,I am trying to communicate with ST25R3920 using S32K116 host MCU. I managed to read some data but they seem meaningless according the datasheet. For example: I was trying to read IC identity register(3Fh) to test that if I am able to c...
Hi,We are testing the M24LR04E-R with NDEF messages and find the speed very slow.We are currently using Android, but we see the same behaviour with iOS.If we write 400 bytes of data as TEXT tag. With this simple code:NdefRecord mRecord = NdefRecord.c...
i used to STRU3993 EvalI got the result based on the following code.I wonder what that result means.It seems to be the result of the antenna performance here.If it is the output of the result for the antenna performance,I wonder what function should ...
Which one is the smallest NFC tag that can be identified by an iPhone?
While trying to read gen2 tags with the ST25RU3993 reader. Reading address 0x02 in the EPC memory bank seem to work, but word addresses beyond 0x7F in the User bank give me an error (ERR_RXCOUNT). I know that the memory is accessible with another rea...
While doing an FTM transmission from RF to I2C and reading the MB_LEN_Dyn register, it will always report a length which is 6 bytes more (or 7 after the increase by one in my code) than the actual message length. Below is the code of the ISR handling...
I am looking to use the code provided (X-CUBE-NFC6) with modifications to have the ST25R3916(lock) and M24SR64(key) to act as a lock and key. I am able to read, format, and write to the tag using the provided program. How would I be able to make each...
Hi, I'd like to use a ST25R3911 in order to detect a tag at approximately 20cm.Do you think it's possible ?--> I'll use custom antenna, and probably a custom protocol in order to read a small quantity of data ( my objectif is to read the data in 1ms)
NFC Tag: ST25DV64KVI2C host: STM32G474I write 5 bytes data 0xA,0xB,0xC,0xD,0xE in FTM mailbox and I want to read these data through ios NFC Tap app, so I enter FTM - Data Transfer, disable Write/Read MailBox Buffer and tap start to read, it takes ver...
Hello, I tried to implement the card emulator using CR95HF to refer to the datasheet, but it failed. Could you provide the sample code data for the cmd read write cmd procedure in the form of Hex value? I'd appreciate your help. Ex)Write cmd 0x 02 04...
