Hi,

there exists a HCI_Set_Event_Filter command in the specification for
this, but actually I never tried it and I don't know how many chips are
really supporting it.

In a word, I would like to know the correct methods to accelerate the connect procedure.

No need to, because the kernel keeps track of creating the ACL link and
it uses the clock offset from its inquiry cache if it is still valid.

I think you are talking about the page timeout. Look at the HCI command
to modify it or use "hciconfig pageto ..." for it.
