Recv failed: Software caused connection abort
The connection will always stall after 10 rounds. The pinged device is Samsung Galaxy S phone. When the same is being pinged from another computer, also running Ubuntu, the connection stays stable until aborted.

Noticed exactly similar behavior reported here: https:/ /bbs.archlinux. org/viewtopic. php?id= 120488 - only common things are bluez and Broadcom bluetooth chip.
