ESP8266: PCD_Authenticate() failed: Timeout in communication.

[steand]

Step 1: Describe your environment

• OS version: Windows 10
• Arduino IDE version: Plattformio (Core 5.0.4·Home 3.3.1)/framework-arduinoavr 1.6.23/framework-arduinoespressif8266 3.20704.0 (2.7.4)
• MFRC522 Library version: V1.4.8
• Arduino device: UNO & WeMos D1 R2 mini/NodeMCU
• MFRC522 device: RFID-RC522 (two different supplier)

Step 2: Describe the problem

On the arduino UNO the code works ready. If I switch to WeMos D1 mini/NodeMCU I get: PCD_Authenticate() failed: Timeout in communication. I test with different card (all can read with my mobil).

Observed Results:

Relevant Code:

#include <Arduino.h>
#include <SPI.h>
#include <MFRC522.h>
#include "Logging.h"

const int RST_PIN = D1; // Reset pin
const int SS_PIN = D8;  // Slave select pin

MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance

void setup() {
Serial.begin(115200); // Initialize serial communications with the PC
while (!Serial); // Do nothing if no serial port is opened (added for Arduinos based on ATMEGA32U4)

Serial.println();
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522
delay(100);
mfrc522.PCD_AntennaOn();
mfrc522.PCD_DumpVersionToSerial(); // Show details of PCD - MFRC522 Card Reader details

Serial.println(F("Scan PICC to see UID, SAK, type, and data blocks..."));

}

void loop() {

if (!mfrc522.PICC_IsNewCardPresent()) return;
if (!mfrc522.PICC_ReadCardSerial()) return;

// Dump debug info about the card; PICC_HaltA() is automatically called
mfrc522.PICC_ReadCardSerial();
mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
// mfrc522.PICC_DumpDetailsToSerial(&(mfrc522.uid));
// mfrc522.PICC_DumpMifareUltralightToSerial();
mfrc522.PICC_HaltA();
mfrc522.PCD_StopCrypto1();

}

bug found. I call mfrc522.PICC_ReadCardSerial(); twice.
