Hi, When I leave my code to play for more than one hour I received the error HardFault_Handler(), I found in registers whats the last line executed before entering in the error function, below I put a picture of this part of the code. Note: That err...
Hi,I've implemented the RFAL-HL ( Higher Layer ) based on X-Cube-NFC5 in our project.Currently, the example only provides us with a way to detect tags only. I would like to know, what's the procedure by which we can send an NDEF data packet to a P2P ...
In my project,, the tags need to be scanned and sent to our created website,, the data needs to get sent via LAN or wifi using LAN module and esp 32.Our code is written on Arduino IDE.My question is that,, can this reader (ST25RU3993) be interfaced...
Hello,I am curious if there is a RFID reader that extends the communication distance for STEVAL-SMARTAG1. If so, could you kindly provide the link and description. Thanks in advance,J.X
I have an application which must send > 100KB/day to an RFID/NFC reader (I'm using the STM25R Disco) - for days and years on end.Looking at the EEPROM spec, it's good for 600k write cycles at 85 °C(That means even at 64Kbit EEPROM, wear leveling wou...
I had downloaded the source code and try to build the project with Xcode 10.2. it show that "Checksign.h" is missing. I cannot find this header in any source folder. Is it a external header?I am new to iOS app development. :grinning_face_with_sweat:...
I use CR95HF with UART communication for some applications. I notice that occasionally (seemingly at random) the CR95 will stop responding to any UART commands. I send an ECHO and receive no response. I have experienced this with several of my own de...
Hello,using STSW-ST25RFAL002 to version 0x020200U (RFAL Current Version: v2.2.0) I encountered a problem in card emulation mode, practically the state machine remaine blocked on the RFAL_NFC_STATE_LISTEN_ACTIVATION state indefinitely rfal_nfc.c: 518 ...
Dear Community,as a hardware developer I'm working on a project with ST25DV Tag.Now I'm facing some problems with the NFC Antenna and would like to try out some double sided ones. I have some example boards and also a list of ST approved antennas but...
