Airport/Bluetooth upgrade from 11n/BT2.0 to 11ac/BLE4.0
The older macbook air (< 2012) uses 11n/bt2.0 but we can not use 'Handoff', 'Continuity' function of yosemite.
To support those we need BLE4.0, can we replace bt2.0 of my 2010-late air (BCM943224PCIEBT2) to ble4.0 of 2013/2014 (BCM94360CS2)
I think that we have to consider the location of the antenna port and the size of card board.
Is this a good question?
