Sorry It is a third party library only

I didn't find it in the sdk 12.3 either. Are you sure they're not from a 3rd party library?

Actually these functions are present in sdk 12.3.I converted sdk 12.3 to sdk 14.2.While uploading bmp180 code alone in sdk14.2,I got answer.But while integrating to proximity code,when i include rtc_config() function,I got fatal error.Also I tried changing the location of rtc_config(),but again getting fatal error.

Please help me out!!

What are these functions bmp180_drv_begin(sensor_callback) and bmp180_drv_start_sensor(&sensor, &m_twi, 0). I can't find them in the sdk.

static void sensor_callback(bmp180_evt_data_t * event_data)
{//SEGGER_RTT_WriteString(0,"hello25\r\n");
	NRF_LOG_INFO("TWI master example init67\r\n");
    if(event_data->evt_type == BMP180_EVT_DATA_READY)
    {
        NRF_LOG_INFO("T = %d | P = %d\n", event_data->bmp180->temperature/100, event_data->bmp180->pressure);
    }
}

This is the sensor call back function

int main(void)
{
    bool erase_bonds;

    // Initialize.
    log_init();
	  lfclk_config();
	  twi_init();
	  timers_init();
    buttons_leds_init(&erase_bonds);
    ble_stack_init();
    adc_configure();
    gap_params_init();
    gatt_init();
    advertising_init();
    db_discovery_init();
    services_init();
    conn_params_init();
    peer_manager_init();
		uint32_t err_code = app_timer_init();
	 // Start execution.
  NRF_LOG_INFO("Proximity example started.");
	 advertising_start(erase_bonds);
 NRF_LOG_INFO("MPU BLE simple example.");
		NRF_LOG_INFO("TWI master example\r\n");
NRF_LOG_INFO("%x",BMP180_DEVICE_ADDR);
// Enter main loop.
 NRF_LOG_INFO("TWI master example112\r\n");
//rtc_config();
NRF_LOG_INFO("TWI master example11\r\n");
 bmp180_drv_begin(sensor_callback);
NRF_LOG_INFO("TWI master example12\r\n");
bmp180_drv_start_sensor(&sensor, &m_twi, 0);
	
		 
		for (;;)
    {
			
        if (NRF_LOG_PROCESS() == false)
        {
					
            power_manage();
        }
			}

I have fixed the previously mentioned error.But now,in main, i have the problem of calling these two functions.

bmp180_drv_begin(sensor_callback);

bmp180_drv_start_sensor(&sensor, &m_twi, 0);

It won't print the temperature and pressure value.I don't know how to solve this issue.Please help me out!!

Thanks in advance!
