I have tried to make a Bluetooth speaker with raspberry Pi three months ago. It was failed because of the old Bluetooth 2.0 USB device. It is too slow to get the smooth audio transferring.
Now I have a new Bluetooth 4.0 USB dongle.
I checked the information from the terminal window.
The procedure of installation is same as
the post I posted before.
The dongle I got is $2.99 each. Good price. After I tested it, I can say Good quality.

I chaecked my inventory. Found two bluetooth USB dongles. I think it is enough. After googling, I found this one.

Fitbit almost one year. I need a USB device to synchronize data it collect. The USB device should work with PC and its program, Fitbit connect.
Now Fitbit syncing support more devices.
Including iPhone 5s, iPhone 5c, iPhone 4s, iPod Touch 5, iPad Mini, etc.
Most important news for me is that it is supporting
Nexus 7 (2013) now.
It means I don’t have to turn on my PC and sit beside it to wait the data synchronizing. I can play my favorite games,Jewel Mania, Fragger, Candy Crush, or Angry Birds, the data syncing is done without further action.
