Bluetooth Problems on Yosemite (Solution: 'Turn Wifi Off' then on again)
If you can not connect/reconnect your bluetooth devices, try "Turn Wifi Off". It seems to 'wake up' the bluetooth and then my devices reconnect.
In my case, after sleep/wake of my MacBook, my bluetooth keyboard & speaker would NOT reconnect. When I 'Turn Wifi Off" my bluetooth starts working again and my bluetooth keyboard & speaker immediately reconnect. I also read on some non-Apple.com forum that sometimes 'Turn Wifi Off' on yosemite makes bluetooth start working again. Other times, 'Turn Wifi Off' followed by 'Turn Wifi' On makes bluetooth start working again.
In my case, whenever I can not get my bluetooth devices to connect/reconnect to my MacBook, I simply "Turn Wifi Off" and it immediately connects.
Please REPLY to the following post if 'Turn Wifi Off' fixes your bluetooth connect/reconnect problems!

Thank You.
P.S. I'm guessing that with the 'Handoff a.k.a. Continuity' enhancements to Yosemeti, which uses Bluetooth to dynamically enable iOS devices to coordinate workflows with MacBooks, that Handoff's dynamic explolitation of bluetooth behind the scenes, which introduces a somewhat new style of load/usage on Bluetooth, that it has messed up the way Bluetooth is managed in Yosemite. I'm guessing that Apple is aware of this and will fix it eventually. Until then, "Turn Wi-Fi Off" seems to do the trick for me when I want to 'wake up' my MacBook's bluetooth and get my external devices connected again.
