I recently bought an external bluetooth dongle to add BTLE support to my Macbook Pro 2011. I'm running Yosemite 10.10.2.
I've read different blogs and posts here, indicating how to enable the external dongle, but they don't seem to work. Following the answers to this AD question, I've tried downloading the Bluetooth Explorer found in the
HardwareIOTools_Xcode_6.3.dmg package. But when I navigate to Tools->HCI Controller Selector, and choose the Broadcomm dongle and click Activate, the built-in Apple BRCM device remains active, and doesn't activate my external dongle.
I've also tried to update the nvram settings and rebooting:
sudo nvram bluetoothHostControllerSwitchBehavior=always
but that too doesn't have any impact.
What am I missing or doing wrong?
