How can I tell what Bluetooth version (i.e. 2.1 + EDR or 4.0) my iMac has installed? I downloaded Bluetooth Explorer and poked around, but I see no information that screams “Bluetooth version” at me. Nor could I find any data online mapping model numbers to Bluetooth versions.
I ask because I’m trying to do some work w/ 4.0 LE profiles. My Mac is an “iMac11,2”.
System Profiler (apple > about this mac > more info > system report > hardware > bluetooth ) will tell you your “LMP version”
lookup that LMP version here http://www.bluetooth.org/Technical/AssignedNumbers/link_manager.htm
The key ones are:
LMP Version -> BT version
4 -> Bluetooth Core Specification 2.1 + EDR
6 -> Bluetooth Core Specification 4.0
