    Arrow Sending coordinates to a NFC tag from 6131 NFC?


    I was wondering, how can I send coordinates to a certain NFC tag through my Nokia 6131 NFC so I can read those coordinates later from it?

    I know how to send URL but no idea how to send coordinates.
    I've tried Google and read dozens of documents and examples but no luck so far.

    I need to send different coordinates to a few NFC tags so I can calculate their distances for later use by moving from one tag to another and reading those coordinates as I go.

    Thanks in advance for any help you can provide.

    You can do that using NDEF Messages.
    There is not (as far as I know) a standard NFC Forum RTD (Record Type Definition) for Coordinates.
    That leaves the chance of creating your own External RTD. The format of the data on the record must be specified by you (the way the coordinates are converted to bytes and vice-versa).

    Read more about this on NFC Forum specifications on NDEF messages.
