iphone - Why is Apple example BTLE-transfer ipad app's RSSI value so bad? -


i having trouble getting apple's core bluetooth btle-transfer app example working because rssi signal strength peripheral central below level allowed central app (-35db).

i have v1.0 apple btle-transfer core bluetooth example app running on 2 brand new ipad minis, , rssi low ( < -35 db) when side side.

oddly, 2 ipad minis w ios 6.1.2 drift above -35 few seconds (range -15 -35ish), below again; , 2 other ipad minis w ios 6.1.3 never above -35 (actual range -48 -36).

if change -35db limit downward connect, still doesn't work because: "connecting peripheral ''." ...so there no real connection.
