The speed download may be affected by the connection interval.  The way it works is that the sensor requests smallest connection interval in the lel2cap_sendConnParamUpdateReq(6, 6, 0, 700);.  The client/master needs to accept this request and set the parameters.  Please check both sides of your application.

are you saying that the issue of slow downloads come from your application? but there is no problem from the ota-fw-upgrade from the sdk? what is your current app environment?

it is tricky to verify your issues since it occur on your application. i suggest getting someone on-site to talk to you instead. can you drop me a pm and i would like to link you to our reps in taiwan.
