    I expect to take sequences of say, 50 temperature measurements expressed by a byte each with values ranging from 0 to 255.

    The micro will transmit them through bluetooth to a tablet running Android 4.4 at a pace not decided yet. Say, for now, every 30 seconds.

    I spent two days already, reading intensively about Android but still have questions:

    a - What application (tablet side) could I use to receive and (save?) them?

    b - What application is actually able to take the above data and plot the values against an X axis (time).

    c - Initially I thought that a .bin file would be involved but it seems that in Android they are different than in Windows and maybe they are not needed at all. The .bin files seem to have a more or less specific use.

    d - The apps I've read about up to now, they all seem able to graph functions but no data values.

    Could anyone suggest how to handle this, based on previous experience. BTW, I am not Java, nor C conversant.

    Gracias for any help.

    Already done. Search Google Play for Bluetooth Thermochron iButton.

    I decided to roll my own. The very basics are solved.

    Here you have it
