What error code are you getting?

Not sure I would do all of this in the timer handler. Try to only start adveertising. Then start to send data after the connection is established and notification has been enabled. Similar to what we do in most/all our examples. i.e. I look at one of the simper examples such as ble_app_uart.

how to do that ? which one command is used to connect to peer device , for disconnect

err_code = sd_ble_gap_disconnect(m_conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION); please have a look at below code , i am advertising after 20 minutes , after connect and i am getting fatal error

static void timer_sensor_event_handler(void)
{
    advertising_start();
    if(connected==true)
    {
nrf_gpio_pin_toggle(19);
ret_code_t err_code= ble_nus_data_send(&m_nus,"hello",25,m_conn_handle);
nrf_delay_ms(10000);
    err_code = sd_ble_gap_disconnect(m_conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);
}
}

Hi,

Not much you can do on the peripheral side. Just make sure you start advertising again after 20 minuttes. If this is a service that is natively supported by the peer (bonded smartphone) it would normally autoconnect. If it is not natively supported by the peer, your phone application will have to enable autoreconnect / background scanning.
