Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
I was trying to setup the software (ST25R010) for NFC reader, and not only was I unable to setup the software but I realized the board malfunctioned at some point. The board initially worked fine but now it shows a reversed error message and I cannot...
For our NFC project, we are developing a mobile application that supports both iOS and Android. We are using React Native along with the react-native-nfc-manager library. Some of the core features include reading and writing raw memory blocks as well...
Hello everyone. I'm currently developing and testing an embedded C software for microcontroller STM32L476 integrated on board ST25R3911B.In order to better understand FTM and its features, I'm trying to use a ST25NFC_Embedded_Lib_ST25R3911B_1.8.0 dem...
Hi all，I now use ST25R3920B as a card reader on the official nucleo nfc08A1 of ST to read cards. However, I found that when the card was detected by 3920B, the current increased to 300mA, but the maximum current borne by PCB was 350mA.Can I reduce th...
I use the Flutter NFC Kit library.I enter the password and then use: Extended Read Multiple Blocks"2033XXXXXXXXXXXXXXX00003F00"Request_flags -> 20Extended Read Multiple Block -> 33UID -> XXXXXXXXXXXXXXXFirst block number -> 0000Number of blocks -> 3F...
Updated the title to be inline with ST community rules. Hi all! So I am looking for a standard antenna which would be suitable for ST25R100-CMET (IC Reader 13.56MHZ 24 UFQFN). This will be used in an alarm module with a lock, so please suggest! Thank...
Dear Sir, ST25R3911B-AQFT, we have noticed that the QFN32 package is different for COO=KR and COO=TH parts, referring to photos attached, is this normal? Is there any updated datasheet or PCN information to reflect such change? The package of ST25R...
I'm using ST25dv64KC memory and need to use Fast Extended Read Multiple Blocks C5h, but I haven't had any success.I'm passing the sequence "22C502E00251678F057ABB000001F00"22 - request flagsC5 - Fast Extended Read Multiple Blocks02 - IC mfg codeXXXXX...
Dear NFC Forum Community, we have recently developed a circuit design using one of STMicro’s latest NFC chips (e.g. ST25R200 as their most recent reader IC). We are very interested in having this design validated under NFC Forum conformance testing. ...
The last few lines of StMicro’s ST25DV-I2C low power application note (high lighted) are ambiguous. Does “ST25DV-I2C” have the ability to read/write EEPROM without power applied between pins VDCG and GND? (YES/NO) Our desired application needs to ...
