ST25 NFC/RFID tags and readers

Resolved! How to read the NDEF message? (M24SR04-Y)

I have a microcircuit M24SR04-Y, on which I recorded information using the NFC.I need to read this information using i2c.I read the datasheet and understood the circuit of communication with the microcircuit.But I am a novice and without an example i...

Resolved! Which is the typical value of the matching impedance that the ST25R3911B should see?

I'm designing the NFC antenna, the EMC filter and the matching circuit, for an industrial NFC application. I'm looking for a good value of the matching impedance that provide the right tradeoff between performance and efficiency

Resolved! I want use ST25R3911B-DISCO write a file ( the bin file) to ST25DV04K .

I use pc software(ST25R3911B Discovery GUI) linking with ST25R3911B in usb.the tag is st25dv04k.My order of operations is | ST25 Tag Editor model | > | ISO15693 model | > | DYNAMIC NFC TAGS| > | ST25DV04K|.I use file transfer model,choice LOAD FILE T...

Resolved! What happens if the ST25R3911B RFI1 and RFI2 input signal peak values exceed the Vsp_a supply voltage level?

Reference is to ST25R3911B data sheet, page 16, section 1.2.3Concern is is the SS25R3911B damaged or just fails to operate properly?

Resolved! Is possible to configure the ST25R3911B chip to send NFC url message only without reading? We would like to use the high-power gain capability of the chip with iPhones.

Resolved! When I do an updateBinary on a ST25TA I get return of f2 2 or f2 3 What is that, it's not quite a WTX, and not quite a deselect?

This is the same question that I posted on the NXP Community "Problems doing updateBinary"I send 16 bytes using the NDEF updateBinary command after the NDEF Select file0x2 0x0 0xd6 0x0 0x4 0x10 0x54, 0x77 0x61 0x73 0x62 0x72 0x69 0x6c 0x6c 0x69, 0x67...

Resolved! Missing 'PICCNFCDEP_Init' function definition in EVAL-ST95HF_FW_V3.7.0 source code

Posted on July 13, 2018 at 12:01Hi, I'm trying to run EVAL-ST95HF_FW_V3.7.0 source code on STM32L4 processor but unfortunately I can't link the compiled objects because of undefined reference to 'PICCNFCDEP_ReplyCommand' and 'PICCNFCDEP_Init'. The d...
