After updating to iOS 15.4 I can no longer read any NFC tags. I believe Apple Pay is working fine. Unlock iPhone, hold NFC tag to top back of phone (without case or other magnetic or metallic materials nearby). Default iOS behaviour should .
First, I apologize for not being able to get the below code to format correctly on .
I'm trying to build a safe that opens when the correct card is read by an RFID . First, I apologize for not being able to get the below code to format correctly on the forum. I've spent the morning trying to get the 28440 RFID reader working in Spin attached to a WX board. The code below will occasionally return the same distinct codes for 3 different rfid tags.
I'm trying to build a safe that opens when the correct card is read by an RFID reader. For some reason, the reader refuses to read the card even when it is enabled (the LED is red). Pressing and holding reset swithc will show green on 28440, and it turns red when reset switch is relased and program runs. Sounds good? However holding my 28141 card up to it produces no response. I checked the current through the RFID reader and when it is active it .
