4. UHF RFID on a M5Core2

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:
    RFID.Set_transmission_Power(2600);
    RFID.Set_the_Select_mode();
    RFID.Delay(100);
    RFID.Readcallback();
    RFID.clean_data();

    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(" ");
    RFID.clean_data();

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

    Hello
    I am in your same situation, but I can´t even with simple reading.
    If you want we can work together since we have the same devices.
    IIFLOW examples do not work, the EPC only shows 6 characters.

    Thanks.

    Hi

    Not sure if this will help. I was in a similar situation. However I found I was using the incorrect Tag type. I needed the following tag type ISO 18000-6C, EPC Class1 Gen2 standard protocol.

    Once I had these tags the example code worked as expected, I now have a functional unit that reads multiple tags using M5Paper and M5 Core with Micropython, and is working well for my project.

    Hello
    I'm going to try, to see what kind of labels I have.
    Thank you

    Hello,
    Yes, they are the ones I have EPC Global UHF Class 1 Gen 2 / ISO 18000-6C uses them Decathlon. I have Core 2 and Atom Lite, it does not work in any of the cases.
    IIFOW does not work for examples and Arduino Libreria either.

    Thank you

    Gleon,
    What Sketch do you use?
    You can't see EPC or Aton Lite or Core2
    Thank s
