UHF RFID on a M5Core2

  • Hi!
    I’ve been trying to compile the demo sketch for multiple reads.

    With some tweaking I was able to compile the demo single read sketch... But i have not been able to compile the multiple read.

    I've switched the library: #include <M5Core2.h> and also the ports for the serial comm:
    Serial2.begin(115200, SERIAL_8N1, 33, 32);

    But i could not make the multiple read sketch to compile.

    Actually, not sure if I'm having problems with this part of the code:

    or this one:
    cards = RFID.Multiple_polling_instructions(6);
    for (size_t i = 0; i < cards.len; i++)
    if(cards.card[i]._EPC.length() == 24)
    Serial.println("RSSI :" + cards.card[i]._RSSI);
    Serial.println("PC :" + cards.card[i]._PC);
    Serial.println("EPC :" + cards.card[i]._EPC);
    Serial.println("CRC :" + cards.card[i]._CRC);
    Serial.println(" ");

    Does anyone have aby thoughts on where to problem could be?
