I have an iphone 4s istalado with ios 5.0.1 and jailbreak the GPS BTstack 1.6.1-29985. The BTstack works perfectly when the iphone is not locked, the bluetoth Turns ON, connects to the external receiver and receives signal to perfection. The problem arises when the iPhone is locked, then stops receiving signal from the external receiver and app I use to record data routes do not get blocked while esubo iphone.

Try to start the ipod and play a song. For the time of playing the iphone holds the connection.

Negative this solution does not work. The problem is that the iphone blequearse bluetoth the connection is cut.

Could you try a different logger app? I've used Endomondo to record my mountain bike trips and that works even when device gets locked.

Hello I tried it with other apps like Endomondo and all feel the same. Leaving BTstack to open the application you want to use is disconnected, as with shareware. I bought my application I have btsatack and same thing happens to me if I had not bought it off when changing the application or by blocking the iphone.
