Why I lose communication with BlueNRG-2 via SWD?

I am able to communicate with BlueNRG-2 either by ST-Link Utility or by Atollic GDB. 
Unfortunatelly, when I start regular work of DTM firmware, these tools lose communication.



What is the reason of that?
Is it caused by going the BlueNRG into sleep mode?


How can I solve this problem?

Having debuger is crucial for bug finding.
