RFID blocking cards, also called security cards or shield cards, are designed to .
it read the tags just fine for a few moments, it did what it was supposed to and dumped the info from the RFID Tag into the serial monitor, and suddenly it stopped reading .
Well let’s make a simple NodeMCU RFID reader using the MFRC522 module, and program the NodeMCU to provide access when the right card is detected. This simple example will read .
However, after setting up the circuit according to the datasheet and running the library main code "AccessControl", the RFID completely stops reading cards. It only works . The RC522 module stops reading cards after running for a long time, about two weeks. After pressing the reset button of the ESP32 module, the module started reading cards .The module is based on the MFRC522 chip from NXP, which supports various RFID protocols, including ISO/IEC 14443 A/MIFARE, ISO/IEC 7816, and FeliCa. This module works on . In this tutorial we will learn How to interface NodeMCU with RC522 RF ID Reader using Arduino library for MFRC522 and other RFID RC522 based modules. This library read .
rfid stops reading after 540
In this article, I will make a tutorial on how to use this RFID reader with a nodeMCU. We can use the same library that was made by miguel just like what we did with an Arduino.
I have re-checked the connections a thousand time but it's not working, the pins are connected as the example says to, and the LED D1 is on (red). Does anyone can help me? For some time I wanted to have an Arduino controlled light switcher for outdoors and few weeks ago I created it, but I have problems with it. I needed to have a RFID reader .

This simple . it read the tags just fine for a few moments, it did what it was supposed to and dumped the info from the RFID Tag into the serial monitor, and suddenly it stopped reading them. Here's the example code, only modification was changing .
rfid reader stops reading cards
Well let’s make a simple NodeMCU RFID reader using the MFRC522 module, and program the NodeMCU to provide access when the right card is detected. This simple example will read the serial number on the Card or Tag, display it in the serial monitor.
However, after setting up the circuit according to the datasheet and running the library main code "AccessControl", the RFID completely stops reading cards. It only works again after restarting it (and sometimes, it takes more than one attempt). The RC522 module stops reading cards after running for a long time, about two weeks. After pressing the reset button of the ESP32 module, the module started reading cards again. 1 - The RC522 stops reading the cards after several reads and will only work again if i reset or reupload the sketch. The number of attempts is random but it ranges from 2-7 times.ESP8266/NodeMCU unable to communicate with MFRC522 RFID reader. I am trying to use the 'DumpInfo.ino' example file to dump an rfid tag, the only changes i have made to the example is changing the pin settings.
rfid rc522 not reading
It successfully connects with WiFi (that I can see via serial monitor) but gives no response when I touch the RFID card to the reader and there is no display of the card UID in the PHP web app.The module is based on the MFRC522 chip from NXP, which supports various RFID protocols, including ISO/IEC 14443 A/MIFARE, ISO/IEC 7816, and FeliCa. This module works on 13.56MHz frequency and communicates using I2C and SPI interface protocols. It operates on a +3.3V/13-26mA Power Supply.
In this tutorial we will learn How to interface NodeMCU with RC522 RF ID Reader using Arduino library for MFRC522 and other RFID RC522 based modules. This library read and write different types of Radio-Frequency IDentification (RFID) cards on your Arduino or NodeMCU using a RC522 based reader connected via the Serial Peripheral Interface (SPI .
