As an update to my post from last week - I have full Continuity working, handoff, sms, calls, airdrop, etc from my mid-2010 MBP to my iPhone6. I am the stock wifi card that came with the laptop. I am NO LONGER using the updated wifi card, nor have I even received the 802.11ac card yet. The only thing I'm using is a $9 BLE dongle and the Continuity config tool released. I was convinced I needed a hardware change to get this working as no HandOff was functioning without it, but today it started working and I have nothing plugged in except the BLE dongle. Seems like just a few reboots was all it needed. Now to decide what to do with this useless airport card I ordered!
