You might also investigate existing serial ports on the device, I have no experience with the galaxy tab, but a quick google came up with this page saying there's already a serial port, and you just need some tricky soldering skills to access it:<div>

<p>Hey,<br>
Yeah I've used Bluetooth before but this will be all integrated into a special case on the tablet (the FTDI is actually for hooking up an Xbee module, as all we're trying to do is use the tablet to talk to some remote Xbee sensors).</p>
<p>We will use Bluetooth if we have to, but apparently the tablet supports FTDI devices somewhat readily (with the instructions given on that site), I'm just missing... something. So I'd like to get that working if possible.</p>
<p>Additionally, this is a custom product that will be sold with the tablet, so other device support isn't a concern.</p>
<p>Really it's just that hosting is the right solution, and I had a tutorial, so not doing it would be annoying.</p><div><div></div><div class="h5">
