ble_app_uart application - UART and BLE Transmission mode.

Question

Hi, I am using nRF52832 module (GAP peripheral, GATT server) with nRF5SDK, ble_app_uart_pca10040_s112 application. 
 
 In ble_app_uart application, how can I ensure that UART is set in Full duplex mode? 
 Also, I would like to know what transmission mode does BLE follows? 
 It would be helpful if you can share any references for both. 
 
 Thanks in advance!

PKANNAN said: I would like to mention that I am quite confused with my understanding on the above statement. What I would like to know is, does UART is set in Full duplex mode in ble_app_uart application, by default? 
 The UART hardware have full duplex capabilities. 
 When it comes to software, the initialization will by default setup the hardware to have full duplex communication. It is application responsibility to enable/disable flow control at the time of initialization and in some examples the HW flow control is enabled by default and in some it is disabled. 
 The library->driver->HAL->Hardware always have full duplex capabilities to send and receive data by default. I hope this helps.
