Dear sir, 

Device name set code is below, and i'm able to change the device name but once reset or OF/ON conditions the existing name is coming, what to to??

static void setDeviceName(uint8_t *device_name)
{
ble_gap_conn_sec_mode_t sec_mode;
BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

/* Change device name */
uint32_t err_code = sd_ble_gap_device_name_set(&sec_mode,
(const uint8_t *)device_name,
strlen(device_name));
APP_ERROR_CHECK(err_code);

/* Store Current connection state od adv lib */
uint16_t m_adv_current_slave_link_conn_handle_saved = m_advertising.current_slave_link_conn_handle;

/* Re-initialize advertising module */
advertising_init();

/* Re-store Current connection state lib */
m_advertising.current_slave_link_conn_handle = m_adv_current_slave_link_conn_handle_saved;

printf("Name has been set %s \n",device_name);
nrf_gpio_pin_clear(GREEN_LED);
}

Thanks & Regards

Then I suggest you start by fixing the errors so that it builds without warnings. If it still does not work, then please let me know how you test in detail. Also you cannot ignore return values. How do you know that sd_ble_gap_device_name_set() is successfull?
