 This doesn't look like it's a buildroot issue at all, you may have more luck on
the linux-bluetooth list. Except, it seems like someone reported a similar
problem there [1] a few months ago with no replies...

 Is bluetoothd running as root? The problem seems to be that it is not able to
set the address of the bnep0 NIC. Or maybe the same address is already in use?
