RFID v2

@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

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.

 * The MySensors Arduino library handles the wireless radio link and protocol

 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * REVISION HISTORY
 * Version 1.0 - Henrik Ekblad
 * 
 * DESCRIPTION
 * RFID Lock sensor/actuator
 * 
 * Use RFID tag to lock/unlock a door or trigger a scene on your controller.
 * This example sketch allows you to add an optional relay or solenoid 
 * which can be activated/opened by RFID or controller.  
 *
 * Use the I2C wiring option for your RFID module and connect to the following Arduino pins.
 * 
 * RFID       Arduino
 * -----      -------
 * GND   ->   GND
 * VCC   ->   +5V
 * SCL   ->   A5
 * SDA   ->   A4
 * 
 * Use normal wiring for NRF24L01 radio
 * 
 * Attach a optional relay or solonoid lock to pin 4

@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

? Offline

@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.

? Offline

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.

jeti

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

jeti

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