After AUX_CONNECT_RSP, mcu send LL_PHY_REQ with 1mbps phy. Advertising goes with 2mbps phy. Could you help how to select 2mbps phy? Image with sniffered ble packets is attached. Advertising parameters:

gap_adv_param_t adv_param = {0};
adv_param.adv_mode = GAP_ADV_MODE_EXTEND_CONN_UNDIRECT;
adv_param.adv_addr_type = GAP_ADDR_TYPE_PUBLIC;
adv_param.phy_mode = GAP_PHY_2MBPS;
adv_param.adv_chnl_map = GAP_ADV_CHAN_ALL;
adv_param.adv_filt_policy = GAP_ADV_ALLOW_SCAN_ANY_CON_ANY;
adv_param.adv_intv_min = 600;
adv_param.adv_intv_max = 600;
adv_param.disc_mode = GAP_ADV_DISC_MODE_GEN_DISC;
adv_param.adv_sid = 0x2;

Also I try to update phy after connect event:

    case GAP_EVT_SLAVE_CONNECT:
    {
        co_printf("Connected\r\n");

        connidx = p_event->param.slave_connect.conidx;

        gap_conn_phy_update(connidx, GAP_PHY_2MBPS, GAP_PHY_2MBPS);

        os_timer_start(&update_param_timer,4000,0);
        ble_fts_on_connected();
        tlakepro_service_on_connected();
        main_task_send_connected_event();
    }
    break;
