Merge ble_app_interactive with ble_app_uart example available in SDK 15.2.0

Question

Hi I am working on nRF 52832 and nrf 52840 dongle. I want UART service to be used in my application and application should allow me to scan peripheral devices with user command via Command Line Interface(Putty). I am trying to merge ble_app_uart and Ble_app_interactive example codes with some modification. 
 Please suggest me the best way to do it...

sorry I might have looked at the wrong application. My suggestion would be to start with the ble_app_interactive and simply add the ble_nus service client into that solution. you can follow the way the ble_bas_c client is included in the solution. basically add all of your files needs (libs, drivers) then your include paths. next step would be to start from the top and work your way down. BLE_NUS_C_DEF(m_ble_nus_c); 
 static uint16_t m_ble_nus_max_data_len = BLE_GATT_ATT_MTU_DEFAULT - OPCODE_LENGTH - HANDLE_LENGTH; /**< Maximum length of data (in bytes) that can be transmitted to the peer by the Nordic UART service module. */ 
 static ble_uuid_t const m_nus_uuid 
 static void ble_nus_chars_received_uart_print(uint8_t * p_data, uint16_t data_len) 
 static void ble_nus_c_evt_handler(ble_nus_c_t * p_ble_nus_c, ble_nus_c_evt_t const * p_ble_nus_evt) 
 static void nus_c_init(void) 
 the above are only a snippet of the function or variable you need to fully copy into your code. The above was taken from ble_app_uart_c. 
 Add all files, includes then work your way down initializing the service and the service handlers.
