Explore-NFC, neard, neardal incompatibilities

Former Member

I have purchased two Explore-NFC boards and connected them to Raspberry Pi 2 B boards.  I downloaded SW282713, which contains three .deb files.  These all install nicely and allow explorenfc-basic to work just fine. 

QUESTION #1: However, the download SW282814 contains neard-explorenfc-0.8.  Within this is a file examples/basic.c.  It uses a structure, neardal_tag, which is incompatible with neardal_tag definition in neardal.h (from the only neardal available, neardal-0.14). Where is the version of neardal that you used to compile basic.c?  It is clearly not neardal-0.14!

I have also attempted to follow the README.md instructions.  Many of the apt-get commands do not work, for those versions are no longer available or the command is incomplete.  I was able to work around each of the inconsistencies in this readme.md file, and get to the point of compiling examples/basic.c by getting an older version from your web site. I can now create my own NFC card reading programs, but this leads to the following question:

QUESTION #2: I would like to use the neard and/or neardal libraries to develop an NFC peer-to-peer capability.  I cannot find any documentation on the API for either of these libraries.  (The only thing I can find is to read the actual C code for neard and neardal examples, which may be woefully incomplete.) Please provide me with documentation or links to documentation describing the API calls available for neard and neardal.

I am not a hobbyist. I am a commercial developer attempting to design a product that would incorporate an NXP NFC chip.

    Hello eddie24

    Welcome to the element14 Community, I will move this over to the Single-Board Computers area as it is a better fit.

     

    Thank you,

    I already have read "Beginning NFC" which I purchased directly from O'Reilly's web site.  (That "Wow eBook" site is saturated with hideous ads all over the site, including obscene ads.  I would advise anyone to scrupulously avoid it. NSFW!!)  I have written a fair amount of code using the Android PhoneGap-NFC library. However, I am now trying to use neard and neardal on a Raspberry Pi with the Element 14 NXP NFC board that nicely plugs directly onto the Pi.  All of the source code and examples are in C (not even C++).  Clearly, the API would be in the form of C function/subroutine/library calls.  I am looking for a "man page" style description of the C-language API calls that are made available by neard and neardal.  I have learned a few of the apparent calls simply by studying the example code.  But, the examples supplied only read tags; none of the examples write a tag or perform peer-to-peer functions.  Therefore, it's a bit difficult to discern the appropriate calls beyond reading a tag.  The link that you provided for the Web NFC API does not appear to resemble any sort of enumeration of C-language API or library calls. If you're saying that neard and neardal should have some sort of "standard" NFC calls, where might I be able to find such a list of such "standard" API calls in C?
