If you use the Gallery app on your Android, you have some handy sharing features such as sending pictures over Bluetooth.
Well, I was trying to push some photos from my Nexus S to my Macbook Pro, and even though they were paired, it was failing. After a few minutes I would get the warning
"Bluetooth audio failed. There was an error connecting to your headset. Make sure it is turned on and in range. The audio portion of the program you were using may have to be restarted"
which was a surprise since I don't have a bluetooth headset.
I tried to re-pair the Nexus and OSX, but no change. After some tests I thought maybe I needed to change bluetooth sharing
and now it works great.
Here's a photo to send
press on the screen to get the menus
and Send via Bluetooth
choose where its going, and on your Mac accept
then on your Android it copies over
