DEEP SLEEP mode & BLE

Hello,

I have a problem with deepSleep mode. I have Client and Server, that communicate together. When Server sends the new date, it has to sleep for 1 second.

if(data_send == TRUE){

	LED_Control(RED);

	data_send = FALSE;

	ConnectionStop();

	CyBle_EnterLPM(CYBLE_BLESS_DEEPSLEEP);

	CySysPmDeepSleep();

	//waiting for wake-up

	CyBle_ExitLPM();

	LED_Control(BLUE);

	ResetControlValue();

}//end if

Do I have to use CyBle_EnterLPM(CYBLE_BLESS_DEEPSLEEP) or only CySysPmDeepSleep()? I have a problem with wake-up. After wake-up BLE the communication between Client and Server  doesn't work....
