Is there any sample code for sending a simple APDU command with the ExplorerNFC board?

Hi,

I'm using Raspberry Pi 2 Model B

1. I just downloaded the sample (main.c)

https://github.com/JohnMcLear/NXP-Raspberry-Pi-Card-Polling-Demo

2. Replace the NXP Reader Library (NxpRdLib_PublicRelease) by the latest version (from neard-explorenfc-0.8)

3. Update the CMakeLists.txt

cmake_minimum_required (VERSION 2.8)

project (card_polling)

#file(GLOB_RECURSE SOURCE_TMP "*.c" )

#list(APPEND SRC ${SOURCE_TMP})

set(NXP_RD_LIB "nxprdlib")

include_directories (

  "/usr/include"

  "/usr/include/glib-2.0"

  "/usr/lib/arm-linux-gnueabihf/glib-2.0/include"

  "${PROJECT_SOURCE_DIR}/wiringPi"

  "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}"

  "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}/intfs"

    "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}/types"

    "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}/comps/phpalSli15693/src/Sw"

)

link_libraries(wiringPi glib-2.0)

set(EXT_LIBS  pthread  m)

add_definitions(-g -O0 -std=c99)

list(APPEND SOURCE "${PROJECT_SOURCE_DIR}/main.c")

source_group(src "${PROJECT_SOURCE_DIR}/main.c")

file(GLOB_RECURSE SOURCE_TMP "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}/*.c" )

list(APPEND SOURCE ${SOURCE_TMP})

#source_group(wiringPi FILES ${SOURCE_TMP})

#list(REMOVE_ITEM SOURCE "${PROJECT_SOURCE_DIR}/${NXP_RD_LIB}/ex/NxpRdLib.c")

add_executable(${PROJECT_NAME} ${SOURCE})

target_link_libraries(${PROJECT_NAME} ${EXT_LIBS})

4. I can now send select AID commands and customized commands

From the sample main.c, after UID is obtained, I add the followings

Thank you for your post Eric,

I have downloaded the latest library "NFCReaderLibraryforPNEV512B-3.010_R3", however, the phpalSli15693 folder was not located. Also, I ran the sample code as is, however, the status return code at the line below indicates PH_ERR_INTERFACE_ERROR  Communication error.

Could you give some guidance on this as to ways I could troubleshoot further to determine what the cause of the error may be or any hints as to what could be causing this.

.

Error here, status code 0x20B:

/* Reset the RF field */

PH_CHECK_SUCCESS_FCT(status, phhalHw_FieldReset(halReader));

Hi,

I wrote some instructions including some example code here.

https://github.com/michaelneurohr/NfcReaderLibrary/tree/raspberrypi

Checkout the two files read-HCE-Android-README.md and read-HCE-Android.c

@Michael

Compiling read-HCE-Android.c works fine, but running it I get an error immediately.

$ sudo ./read-hce

Start Example: Read NDEF from Type 4 Tag

Line: 153   Error - (0x0789) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h

Thanks,

Wolfgang

Hi Wolfgang,

did you kill the explore-nfc daemon running in the background in case you installed the EXPLORE-NFC software before? The daemon might have the EXPLORE-NFC allocated in your case.

Michael

Hi Michael,

error message is the same, no matter if the daemon is running or not

Michael,

looks like your missing this in your code:

$ diff ../../NfcReaderLibrary/read-HCE-Android.c read-hce.c

150c150

<     phbalReg_RpiSpi_Init(&balReader, sizeof(phbalReg_RpiSpi_DataParams_t));

---

>     status = phbalReg_RpiSpi_Init(&balReader, sizeof(phbalReg_RpiSpi_DataParams_t));

Yes, you are probably right. Depending on the initial value of status, the code works or not. Thanks for the note. I'll correct that.

Michael
