No payload flag lets you still examine/access header bytes. Create example showing this, but no unit tests.
Not tested but demonstrated in NdefWithoutPayload example.
I think the tests were broken (not up to date with refactored functions) when I forked the library, so I don't know whether these tests previously passed.
Work in progress.

const char * might be technically better, but String is preferred for Arduino libraries because it's easier for beginners

Agreed. I may have run into out of memory problems in my own applications with this library, especially on ATmega328P, and avoiding Strings was a way to mitigate this.

Can't remove the language code 'en', it's required for text records. Ideally it would default to en and allow users to override.

I don't remember why I did this. Possibly because it was confusing me and I wanted a more manual way of writing the data, which looks like it should have been to call the 2-argument version of this function with the second argument empty.
Restoring the default encoding here will probably require changes to a handful of calls in unit tests, i.e. from addTextRecord(text) to addTextRecord(text, "")

@eecharlie Thanks for the pull request. Since I've merged #21 there's conflicts with this. Unfortunately this pull request is huge and changes a ton of things. Generally multiple smaller pull requests are better. I'm going to leave the pull request open since I'd like to manually add NTAG support from your branch, but I don't want stuff where you change the function signatures. The static buffer stuff looks interesting. Debounce support is good. I need to look into the encoding fixes for indexes > 8-bit. I'm interested if you have cases that demonstrate the bugs. |

@eecharlie I'll see if I can extract some of the stuff from your branch. If i run into trouble I'll ask questions. |

Re: 8-bit vs 16-bit indexing, taking a quick look at my commits in which I did this, I may have written a unit test around this, see |

This is my first time submitting a pull request on Github!
I brought in an ntag class originally by LieBtrau that I thought did well as included in this library. I made updates to it to facilitate creating and writing NDEF messages to NXP 'ntag' nfc chips easily, with a direct I2C interface. I also fixed a number of bugs in the existing NDEF message & record classes that appear as soon as things get longer than 8-bit indexing can handle.
There is an added dependence on a Bounce2 button debounce library that I don't love, and some commented out I2C diagnostic code, but otherwise I think this is in good shape and well tested.
