Hi. I'm getting weird data when reading UID from ST25DV04K via i2c.Tag id should be 0E 02 24 00 F3 DF 43 BDWhen reading via i2c HAL_I2C_Mem_Read( nfcI2c, ST25DV_Address_E21_read, UID_ADDRESS, 2, nfcUID, 8, 0xFFFFFF );i'm getting 00 02 24 00 F3 DF 43 ...
Hi ,is there any user manual " how to connect ST25RU3993 UHF module via raspberry pi " please send if any documents
I'm picking up a design from another engineer, and we've noticed the most recent hardware revision of our board has a sense range of approximately half of the previous version. We're using the same antenna and matching network, same layout and compon...

Hello,we have developed a custom antenna and modified the reader circuit a bit to our needs, but are heavily struggling with reading performance. While we were able to read up 17cm above the MB1441-C Discovery Board using ISO15693 tags, our own circu...
Posted on June 17, 2014 at 11:27Hi I'm using the M24LR04 in Harvesting Mode to supply an STM32L151. When the uC powers up, it reads data from an sensor and write them to the M24LR. This is than read from an NFC Handheld.My problem is, when the Hand...
Hi all,I put the EH_MODE to 0 to activate Energy Harvesting. The EEPROM is filled with zeros, so that the smartphone cant read a NDEF message but trying it for some time. I am measuring the voltage on EH, in parallel i added a LED to visualize the EH...
We are trying to implement UART functionality in ST25R3911B-DISCO board.In firmware side we have implemented all the functionality on the board and it is working properly, we have tested it by sending data (formed using frame structure) by serial ter...
HiI have discovery M24LR and CR95HF demonstration board, I read and write data by ST application software successfully but when I use DLL file and LABVIEW software according to AN3954 I read just strange data, for example when I read data from tag I ...
I am not able to find proper examples and/or documentation on how to add RAFL to my project.Looking into the rfal.chm file in RFAL there is an example but it does not work for me ?When I am looking in X-CUBE-NFC5.chm there should 4 examples but its e...
