nrf9160 lte_handler() functuion not working properly

[bhanu prakash]

Hi,

I have using  lte_handler(const struct lte_lc_evt *const evt)  function to get the connection details.

I'm facing a problem when i remove the antenna its still show LTE connected  and pushing data to AWS but in AWS we are not getting any data after that i tried to reset the device then its showing LTE not available may i know why lte_handler not giving LTE not available after remove the antenna

static void lte_handler(const struct lte_lc_evt *const evt)
{
    switch (evt->type)
    {
    case LTE_LC_EVT_NW_REG_STATUS:
        if ((evt->nw_reg_status != LTE_LC_NW_REG_REGISTERED_HOME) &&
            (evt->nw_reg_status != LTE_LC_NW_REG_REGISTERED_ROAMING))
        {
            printk("Network registration status: %d\n", evt->nw_reg_status);
            if (!lte_connected)
            {
                break;
            }

            lte_connected = false;
            /* Notify main function that LTE is disconnected */
            lte_cb(LTE_CONNECTION_DISCONNECTED);
            if (k_delayed_work_remaining_get(&lte_reconnect_work) > 0)
            {
                printk("LTE Reconnect work already scheduled\n");
            }
            else
            {
                scheduleLTEReconnect(lte_reconnection_delay_s[atomic_get(
                    &lte_reconnection_attempts)]);
            }
            break;
        }

        printk("Network registration status: %s\n",
               evt->nw_reg_status == LTE_LC_NW_REG_REGISTERED_HOME
                   ? "Connected - home network"
                   : "Connected - roaming");
        /* Notify main function that LTE is connected */
        lte_cb(LTE_CONNECTION_CONNECTED);

        k_sem_give(&lte_connected_sem);
        k_delayed_work_cancel(&lte_reconnect_work);
        atomic_set(&lte_reconnection_attempts, 0);
        lte_connected = true;
        break;

    case LTE_LC_EVT_PSM_UPDATE:
        printk("PSM parameter update: TAU: %d, Active time: %d\n",
               evt->psm_cfg.tau, evt->psm_cfg.active_time);
        break;

    case LTE_LC_EVT_RRC_UPDATE:
        printk("RRC mode: %s\n", evt->rrc_mode == LTE_LC_RRC_MODE_CONNECTED
                                     ? "Connected"
                                     : "Idle");
        break;

    case LTE_LC_EVT_CELL_UPDATE:
        printk("LTE cell changed: Cell ID: %d, Tracking area: %d\n",
               evt->cell.id, evt->cell.tac);
        last_cellID = evt->cell.id;
        last_tac    = evt->cell.tac;
        break;

    case LTE_LC_EVT_EDRX_UPDATE:
    default:
        break;
    }
}

 if ((err = lte_lc_connect_async(lte_handler)) != NBIOT_ERROR_OK)
    {
        printk("Modem could not be configured, error: %d\n", err);
        errorHandler_process(err);
    }
