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.
