The one thing I might suggest is providing a shorter Refresh Interval in the Advanced Options menu, eg as little as 20 or 40 msec if possible, then the servo responsiveness would be maximal.
My next task is learning how to write my own Android BT apps. BTW, can you tell me which tools you used?
this afternoon, we loaded Joystick Commander into a friend's Samsung Galaxy 3 cellphone running Android 4.1, and it worked perfectly in commanding my BT-Arduino1284 board and servos, so everything good. He was impressed, and not even an Arduino guy.

BTW, the Galaxy phone guy [non-techie] was totally amazed how he could suddenly use his Android phone to control the world, ;-),
Edit:I just tested V2.35 with the Pan/Tilt robotAt 25ms, movements are much smoother smileyI will upload this version to Google Play later todayThanks for your suggestion
...you cannot tell from the Android screen what is the state of the Led on the Arduino, in the sense that you don't know what was the last keypress made - on or off. I guess there is no option for feedback from the Arduino board back to the Android device, but it might help to put some marker on the Android screen to indicate the last key pressed. Like a little marker that comes on, separate from the on,off keys.
Holydays? Where the heck does one go on a holiday when he lives in a resort town like you do? LOL. Maybe the beach. Bon chance.
I happen to have this one on hand, so I plugged it into my Arduino1284 board [which just happens to have a convenient XBee socket], and the JoystickCommander worked right off without any muckaround, so it looks like the "default" mode of the BTBee is the same as for the other small BT modules cited earlier. Again, 2 wire control - Rx, Tx, 9600bps, code=1234 - and go. So, versatility increases.
And never tell anyone in public what your specific plans are, just general stuff like "Well, maybe we'll head south, or maybe east, have to see how it goes", LOL. Talk about intrusiveness, this article may be of interest! Do a google search on "WSJ How Kid Apps Are Data Magnets". I find the direct link gets highjacked. "Big Data" knows more about you than your own govt. C'est la vie. Neuromancer in action.
I've started reading a book on Android development. Install about 700-800 MB of dev tools (java sdk, eclipse, eclipse android plugin, android sdk, maybe some others), and learn how they work, and maybe 3 months later you'll have a nice 47KB .apk app
