Re: endless loop in client.c when read request is rejected

  I am not sure what effect bt_io_set should have to improve the

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.

Try compiling a recent development kernel. I recommend Gustavo
Padovan's tree (master branch):
git://git.kernel.org/pub/scm/linux/kernel/git/padovan/bluetooth-next-2.6.git
