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!!!

some questions about the issue:

1.  if the version before 6.4 is ok for the connection.

2.   you mean you are using a lower Wiced version , right ?

merge wiced6.4 ble firmeware use chip CYW43438A1

if appropriate , Could you please share the files you already merge ?

I will have a test based on 6.4 .

some replay:

1.  the version before 6.4 connection status is ok.

2.  I means I try to plant the wiced6.4 to current environment with ble firmeware for CYW43438A1.plant file from:WICED-Studio-                     6.4\43xxx_Wi-Fi\libraries\drivers\bluetooth .major used file is :43xxx_Wi-Fi\libraries\drivers\bluetooth\low_energy    firmeware and  BTE.

    and bluetooth_low_energy.FreeRTOS.LwIP.ARM_CM4.release.a. It seems run ok and can connect to mobile phone and cyw20736.so may     you can try to connect with CYW20706A1 and CYW20706A2. we set the BT_CHIP_XTAL_FREQUENCY := 37_4MHz

3. the merge file run on our tools with protocol,may be can not control dierectly.

thanks for your support!
