pn532 card emulation mode
I want to konw pn532 card emultion . I success running "iso 14443-4A emulation mode" but it have not block data like mifare card . How can i make block data ? what frame is run "mifare classic card mode" . And in virtual card mode in samconfiguration , how can i get sam ( secure access module)?.
I have arduino mega adk , and nfc shield v1.0 ( pn532) . In this situation , how can i connect "sam" to nfc shield (pn532 )? . please help me .
I believe that if configured properly the PN532 can perform card emulation with a smart card that is compatible with SWP/HCI protocol (single wire connection, ETSI TS 102 603, 102 622).
If you can get a sample test card that supports this protocol, and for which you know the keys, then you could do APDU (ISO 14443-4) card emulation.
You can use PN532 as a NFC tag 4 card which can contain a NDEF message (block data?). If you use Arduino, https://github.com/Seeed-Studio/PN532 is for you.

I am trying to integrate an RFID1356MIFARE, which uses NXP PN532, with an ESP32-EVB using their UART capabilities.
The NXP docs states that the PN532 is able to communicate on High Speed UART.
I am trying to use 38400 because that's the baud rate fixed by the reader that I'm using.
I've found a modified Adafruit PN532 library that added HSU support. This library states that HSU uses 115200 baud rate.
Now, I've modified PN532_HSU.cpp, where we can find:
void PN532_HSU::begin()
{
_serial->begin(115200);
}
into
void PN532_HSU::begin()
{
_serial->begin(38400, SERIAL_8N1, 36, 4);
}
Unfortunately, I haven't been able to establish communication between the reader and the ESP using this method.
I am able to get a readable output using normal Serial.read(), so UART communication works, but that's not how you read MIFARE cards.
I don't know what the problem is.
What do you think ?
[EDIT]
I went through the documentation and here is what i suggest: If you have a USB to serial device use it to directly connect reader module to computer else connect it directly using mini USB port in module. the follow following steps:
Put device in UART/ USB CDC mode depending on how you connected device to computer. Exact method to do this is provided in operation section of documentation
Use picoterm / screen or other serial terminal (if you are using Linux) or just use Arduino serial monitor with correct baud rate to connect device.(115200 for USB and 38400 for UART)
Type in commands listed in COMMAND SET FOR CDC AND UART MODE section in documentation to check if module is working or not.
Place some cards over reader to check what response does module sends when card is detected.
Use this information to develop your own library for reader.
It will not work with regular PN532 libraries. Instead you'll need to use regular Serial read and write to communicate.

PN532 datasheet says host interface is selected by pulling up/down I0, I1 pins of device. For HSU both pins must be pulled down. This is implemented in hardware so you need to verify if the mode you want to use is set.
Looking into the link you posted for module, it says that it uses another micro-controller on board to extend communication capabilities, so maybe you need to use driver for that specific controller firmware? The link seems to have document explaining how to setup different communication system in Document section, please have a look there and check if it works.

Im having a problem with switching a Mifare Plus SE from SL1 to SL3, using acs acr122U with pn532
In SL1 the card is detected as a Mifare Classic (Same ATR) and to perform the switch i need to activate the comunication in 14443-4 and do the auth command with the SL3 switch key. I trying to activate the comunication in 14443-4, but im not finding how.
In other card which its already in SL3 (Also on SL1) the card is activated without problems in 14443-4 and i can send the mifare plus operations without problems.
Im using Smartcardio and transmitcontrolcommand to send the commands to the acr122U trying to use these commands from the PN532 :
-inAutoPoll (Which detects the card as 10 (mifare card, not 14443-4 card)
-InListPassiveTarget (Actives the card as mifare classic too)
-inATR (Which ends with a timeout)
I tryed to inRelease and reactivate again, is not working neither.
Thanks for your time
The problem you are facing is MFP in SL1 acts as a MFC, and does not advertise support for 14443-4 in its SAK. Most high-level libraries will simply not try to send RATS to switch to -4.
For MFP authentication command to work on 0x9001 (prerequisite for switching to SL3), you actually have to be in -4 mode, so you'll have to force sending RATS to get to -4, even if not advertised by card. Depending on your NFC library's API, this may not be possible.
For implementation in backend-agnostic code, I ended-up reimplementing -4 framing and using low-level communication APIs just for this case.
Once in SL3, -4 support is advertised, and switching happens transparently in most communication libraries.
I have an arduino Uno which collect data from sensor, i want to send this data to the cloud using wifi esp8266 who support SSL using the library WifiClientSecure, is there an alternative to send data from arduino to the esp card and esp8266 read this data and send it after that to the cloud, i'm able to work with mqtt but i want to know if there is a way to have a directly connection between the arduino uno and esp8266 without having a third part, any help will be gratefull.
According to my research, the ESP8266 AT Command API does not support SSL. This means you will need to use the Arduino (as an FTDI converter) to program the ESP8266 with custom firmware. This will enable you to use WiFiClientSecure and pubsubclient.
To use the Arduino as an FTDI:
load a sketch that does not use Serial, such as the "Blink" example
connect the Arduino's TX pin to the ESP8266 RX pin
connect the Arduino's RX pin to the ESP8266 TX pin
Now you need to setup Arduino IDE so it can program an ESP8266
In Arduino IDE -> File -> Preferences, paste this into the Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json (just copy the link as it is instead of clicking)
go to Tools -> Boards -> Boards Manager. Find "esp8266" in the list of boards and click "Install"
Set your board to "Generic ESP8266 Module" in Tools -> Boards
Arduino IDE is ready! But before you caan program an ESP8266 with it you need to connect a reset button and a program button to the ESP8266.
connect a push-button between GND and the ESP8266 GPIO_0 pin
connect a push-button between GND and the ESP8266 RESET pin
add a 10K-ohm pull-up resistor between 3.3V and ESP8266 pin (defaults the reset pin to HIGH)
When you are ready to upload a sketch to the ESP8266, use those buttons like this:
press both buttons
release RESET button
release GPIO_0 button
This puts the ESP8266 in program mode! You should now be able to click the "Upload" button in Arduino IDE. I would suggest using one of the provided ESP826a6 example sketches (like this one) to test everything out.
Here's an overview of the project:
. Arduino Uno sketch: read sensor data, send via Serial to ESP8266
. ESP8266 sketch: connect to WiFi network, receive sensor data from Serial, send via WiFiClientSecure to the cloud.
I will leave the actual code of these two programs up to you, but if you get stuck just leave a comment. Hope this helps!
I'm making an android NFC app using Mifare Classic tags. This app is working good.
However, not all Android device have a NXP NFC chip, some have a Broadcom NFC chip which does not support Mifare Classic tag.
So, for this kind of device I'm trying to use the NXP NTag213 or NTag216 tag which are supported by Broadcom NFC chip.
I used the "NXP TagInfo" app to try to read this kind of tag and in the techList the tag is known as [MifareUltralight-NfcA-Ndef-NdefFormatable].
I had a look on NXP datasheet and it stated that you can write data on NTag21X with Ndef format.
I can get an Ndef instance from my NTag but when I try to write my NdefMessage, everytime I get an IOException when I try to get the connexion by ndef.connect().
Do you have any idea why ?
i m new in windows , while reading WDM driver , i encountered about device object (PDO and FDO) .I m not able to visualize why we need 2 different device object as after loading the driver why we again create FDO in ADDDevice routine . we can use PDO there as it represents same device.
The PDO and the FDO have to be separate objects because they use different device drivers. For example, a PCI NIC device will have a PDO generated by the device driver for the PCI bus, and an FDO generated by the device driver for the NIC.
Occasionally the bus and the device do share the same driver, in which case you don't need an FDO. You can use a raw PDO, which combines a PDO and FDO in a single device object.
See Example WDM Device Stack in MSDN for a picture, and PDOs, part 1 for a short description.
