RFID v2



  • Has anybody updated the RFID-Sketch to MySensors v2 ?
    It´s not in the examples-list 😞

    Thanks, Dave


  • Mod

    @davedeluxe the RFID example depends on an external library. To avoid conflicts, examples depending on external libraries are in a separate git repository (since v2.0). You'll find it at https://github.com/mysensors/MySensorsArduinoExamples/tree/master/examples/RFIDLockSensor



  • THANK YOU!!



  • Has anyone got this working.

    I have connected as instructed, in the sketch and upload the sketch from the link. But my sensor I just trying to connect.

    can anyone help here?

    @fleshfear what do the logs from your gateway say?
    The node is onable to get a response from the gateway. See https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help for information on how to read the debug log.



  • im not getting anything from the logs on the gateway, so I seems that the node is not getting connected to the gateway.

    but if I swap the RFID with a pir instead same wiring and all, only added the wire to the pir and swapped the power wires to the pir. Then it works perfectly.

    The setup is:
    Arduino Pro Mini 328 3.3v
    NRF24L01+
    PN532 NFC RFID Reader/Writer Module V3
    1Pc DC-DC Boost Converter Step Up Module 1-5V to 5V 500mA

    and this is the sketch, where you can see the RFID should connect to A4, A5, which i have solder on to the pro mini.

  • okay, i actually found the solution. As the RFID and the radio was powered from the same 3.3 pin on the arduino i think the radio didn't get enough power. So i moved the RFID to a externel power source. And that did get the node to boot, but now it says:

    Couldn't find PN53x board
    

    it maybe can be the I2C mode, but i not actually sure how to set this. now i have set up like this

    0_1478726411089_FullSizeRender.jpg



  • @fleshfear sorry that i can not help, but i just ran into the very same issue... any solutions yet or at least reasons for the

    Couldn't find PN53x board
    


  • @jeti the first thing was not enough power to the radio, and i think the next thing is the I2C mode. But it seems that i have set that one up correctly also so im not sure now.

    Im download a raw PN532 Libary with exemples to see if it the board, or maybe something with mysensors.



  • i got it working.

    i sat the board in I2C Mode, channel1 = on and channel2 = off.
    Then i powered the PN532 board on a external power source.

    Before i did a step up to 5V, that was wrong it should only get 3.3V.
    And the arduino GND should be connected to the external power sources GND as well, to make a common ground.

    Hope it helps.



  • @fleshfear great! I will try it as soon as i can!



  • @fleshfear: ok got it also working. Thanks. mine works with 3.3V and 5V
