write only one record on multiple records #181

Closed lezardrouge closed 9 years ago

lezardrouge commented 9 years ago

Hello, Is there a way to write only in a record without deleting the others already set ? For example my payload contains a record with text and another with some other data, let's say an url ; I want to rewrite only the text (exact same length) and do not touch the url. I would like to avoid to rewrite everything because I have 8ko of data and it takes too much time (and it's also dangerous to rewrite this data). Thank you

You should do a read function, append to an object, then write...

@lezardrouge the underlying APIs only write the whole NDEF message, so @JohnMcLear's read, append and write solution is the best way to do this.

Thank you both for your answers. @don when you talk about the underlying API, is it a limitation of Cordova or it would be the same problem with a native app ?

@lezardrouge you'd have the same problem with native Android too. You need to write the complete NDEF message, you can't update an existing message.
