The source code for Nordic's example apps is available - so you can use that as a starting point

You can send data from the nRF51 using the ble_nus_string_send function in the ble_app_uart example

uint32_t err_code;
uint8_t data[20];
sprintf((char *)data, "User-data %d", user_data);
            
//Send user data to nRF Toolbox app
err_code = ble_nus_string_send(&m_nus, data, sizeof(data));
APP_ERROR_CHECK(err_code);
