I've got a situation where I need to communicate wirelessly between a bluetooth-enabled Android device and a digital scale which can be accessed digitally via USB.
While normally I would be happy to just use one of the new bluetooth human scales, the scale needs to be officially certified and I haven't found any certified bluetooth-enable scales so far... and since it's certified hacking the scale itself is out of the question. So what I'm left with is a certified scale with a USB interface that I need to access via a bluetooth-enabled Android device.
From what I've understood, I could simply plug my USB into the Arduino and then have it do data i/o via the bluetooth mate.
So my question for those more experienced than I : are things so simple, or am I missing something? will there be a lot of Arduino coding to do or will this work out of the box? with these models can I count on a strong, reliable bluetooth connection? a bluetooth connection that had to be constantly re-established would completely ruin the interest of the project...
