STM32 uart communication with Xbee s8

Hi all.
My product is based STM32F030 and uses Digi Xbee s8 for wireless communication.
The Xbee module is connected to microcontroller over UART2. I am using STM cube lib for my development. 
I am trying to establish communication between two Xbee devices. The problem is when i operate device in debug mode all the communication takes place very fast, But if i disable debug and try to communicate it takes a significant time. I have absolutely no clue what magic the debugger does but it works.
Can anybody help me with this?
