Configuring BLE UART Application

[matt_bo7]

I am new to the Nordic BLE tools, and I am trying to use the Nordic ble_app_uart sample project so that the I can send data over Bluetooth to a smartphone application.  I am using a Taiyo Yuden evaluation board to program the NRF51822 BLE module.  I used the following custom_board.h file with defined UART pins and the ble_app_uart project from the Nordic SDK, which allowed me to display data to the terminal application (TeraTerm) by using printf().  

#ifndef CUSTOMBSP_H
#define CUSTOMBSP_H

#include "nrf_gpio.h"

#define LEDS_NUMBER 1

#define LED_START 23
#define LED_1 23
#define LED_STOP 23

#define LEDS_ACTIVE_STATE 0

#define LEDS_LIST {LED_1}

#define LEDS_INV_MASK LEDS_MASK

#define BSP_LED_0 LED_1

#define RTS_PIN_NUMBER 0
#define TX_PIN_NUMBER 1
#define CTS_PIN_NUMBER 2
#define RX_PIN_NUMBER 3

#define BUTTONS_NUMBER 1

#define BUTTON_START 17
#define BUTTON_1 17
#define BUTTON_STOP 17
#define BUTTON_PULL NRF_GPIO_PIN_PULLUP

#define BUTTONS_ACTIVE_STATE 0

#define BUTTONS_LIST {BUTTON_1}

#define BSP_BUTTON_0 BUTTON_1

How could I alter this board file and/or the default ble_app_uart project so that I can send data over bluetooth instead of displaying data to TeraTerm?

You mean this one:

See the Nordic UART Service (NUS):

http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/ble_sdk_app_nus_eval.html?cp=4_0_0_4_1_2_24

Although the example uses the UART, and the BLE Service has "UART" in the name, note that the NUS actually just transports any arbitrary data  - it is in no way tied to the UART hardware peripheral.
