    Mark of bleprofile_SendConnParamUpdateReq, impact?

      There is a slow speed via OTA with BrCM 20737s chip with Samsung handsets even if we 


      add in Ws_upgrade_ota.c


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


      but it doesnt work and ota speed near 20min.




      However if we mark this line below in encryption_changed(HCI_EVT_HDR *evt)() in  hello_sensor.c


          // 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);




      it can work with only 2min ota. However, we disable a refered speed from slave to master...


      is it impact any issue for instance, master auto set a interval speed but slave can not support it to cause link-drop or other issue???
