[Bluez-devel] does flush_to in l2cap setsockopt currently do anything?

[Albert Huang]

Hi all,

I was poking through the sources while trying to find an easy way to
set the ACL automatic flush timeout with an l2cap socket.

Does setsockopt(s, SOL_L2CAP, L2CAP_OPTIONS, ...) cause the underlying
ACL automatic flush timeout to change?  It doesn't look like flush_to
is being used in net/bluetooth/l2cap.c:setsockopt

Is there an easier way of doing it short of extracting the underlying
ACL connection handle and then sending an HCI
Write_Automatic_Flush_Timeout command packet to a separate HCI socket?

Regards,
Albert

it is doing nothing at the moment.

May you wanna look at the cmd_info() part of hcitool.c.
