      Hi all

            Recently, i try to plant wiced6.4 ble firmeware use chip CYW43438A1,and used only low_energy mode not dual_mode,when i plant success and try to test it,CYW43438A1operates as a central and connects to a peripheralfind, it can not connected to CYW20706A1,when connected it auto disconnected rapidly,the disconnect reason is :0x16,also the MTU didn't get;

      but when I use mobile phone or  chip CYW20736 it connect ok and communicat well.

      the connect api set as :

      wiced_bt_gatt_le_connect (conn_param->bd_addr.mac_addr,

                                              ble_mac_type,

                                              BLE_CONN_MODE_HIGH_DUTY,

                                              TRUE);

      the other connect paprmeter set as:.security_requirement_mask = BTM_SEC_NONE,

              .conn_min_interval            = 24

              .conn_max_interval           =40

              .conn_latency                    = 0

              .conn_supervision_timeout     = 700,

       

      thanks!!!
