Download Log after re-connecting
I have implemented the Free Fall Tutorial, with a change, I've added a button to download the log, separated from the stop logging button, and I don't understand why I can't download the log if I have reconnected with the board, Example:
I connect with the board, click start logging, then i click back on the phone, re-open the app, re-connect with the board, and then click the download button.
In this case, the download is empty.
I'm missing something, someone can help me?
Edit: I have another question: Can you limit the metaboard to connect it with only one mobile phone? So if I connect my mobile to the metaboard, configure it so other mobile phone can't connect with it in the future.
