  I am not sure what effect bt_io_set should have to improve the
security (bonding?), but the code simply has no effect in my
environment (with 2.6.39.1 kernel and latest bluez), therefore the
read_req, error_response will continue until link is disconnected.

bt_io_set(..., BT_IO_OPT_SEC_LEVEL, BT_IO_SEC_HIGH, ...) will trigger
SMP pairing (and block further writes until pairing is complete). I
believe you see the loop because your kernel does not have SMP
support, which has been added upstream only a few weeks ago (so should
come only on 3.0, I believe). Therefore SMP does never happen in your
case.

Forgot to mention: I still think we need a fix on BlueZ though, which
cannot assume SMP pairing will succeed. Therefore we should have a way
to abort the write attempt.
