By using forum suggestion, we use

            // to make upgrade faster request host to reduce connection interval to minimum
            lel2cap_sendConnParamUpdateReq(6, 6, 0, 700);

   

in ws_upgrade_ota_handle_command()

   

however, we find there is big slow different OTA speed toward Samsung handset when device in slave role.

   

 

   

we try to mark this function,

   

    // We are done with initial settings, and need to stay connected.  It is a good
    // time to slow down the pace of master polls to save power.  Following request asks
    // host to setup polling every 100-500 msec, with link supervision timeout 7 seconds.
    //bleprofile_SendConnParamUpdateReq(80, 400, 0, 700);

   

in encryption_changed(HCI_EVT_HDR *evt)()

   

we find there is a speed improve for Samsung handset and in our sys. config, security engine is diabled.

   

We question that is it useful and used in BLE-link once security is diabled and also why to mark it,

   

    //bleprofile_SendConnParamUpdateReq(80, 400, 0, 700);

   

it can work with Samsung and any other side effect on other handset if we do it????

Actually not sure if we have a way to speed up OTA... I guess you just have to try it out on the major android handset brands.
