Guidance on Writing UHF RFID Tags Using ST25RU3993 Generic Commands

Pooya · ‎2024-10-29

Hi, I am using the ST25RU3993 Reader Suite for communication and register access with UHF RFID chips. However, I am currently facing challenges in determining the correct data bit length, data arrangement, and specific command codes required for effective communication. While I understand that the device operates in compliance with the EPC Gen2 protocol, I have not found documentation covering these particular details.

I would greatly appreciate any guidance, application notes, relevant documentation, or example commands that could support my efforts to write data to specific memory locations or registers on RFID tags using the ST25RU3993’s generic command function.

Welcome @Pooya, to the community!

You asked a question about the ST25RU3993, which is unfortunately already obsolete and for which there is no more information, at least from STMicroelectronics. If at all, information can only be found in archives somewhere on the Internet.

I am very sorry not to be able to give you a more pleasant answer.

Regards
