1. The problem now encountered, the phone into hibernation after the wake, the app software and CC2541 communication is not normal, but CC2541 still detect when the connection state. How to solve this problem? Will the activity be recreated after the phone wakes up?

Getcanonicalname ());Ten    if(NULL!=WakeLock) { OneLOG.I (TAG,"Call Acquirewakelock"); A Wakelock.acquire (); -    } -   } the  } -  -  //release the device power lock -  Private voidReleasewakelock () { +   if(NULL! = WakeLock &&Wakelock.isheld ()) { -LOG.I (TAG,"Call Releasewakelock"); + wakelock.release (); AWakeLock =NULL; at   } -}
