Question

I m trying to read the accelerometer for a longer period of time (between one and two hours).

However, when the iPhone goes to sleep and locks, the reading of the accelerometer readout is paused.

My setInterval timer seems to be running fine though. I can also play sounds.

I see two solutions

a) Find a way to read the accelerometer while locked b) Find a way to prevent the lock

I m using Titanium with JavaScript.

Answer 1

In 0.9+ you can do the following:

Titanium.App.idleTimerDisabled = true;

Answer 2

See docs for [UIApplication sharedApplication].idleTimerDisabled = YES

Answer 3

Appcelerator will include this in version 0.9

Answer 4

If it s actually locking (and not just sleeping) that causes the lock: Settings -> General -> Auto-Lock -> Never
