Hi,
I have noticed with 2.6.27 that a bluez receiving side of l2ping will
detch the ACL connection (preventing further l2cap echos) after 10
seconds. HCI log below.
Is this by design, or was it unintentional?
I notice the OSX stack will detach after 60 seconds, so maybe it is by
design, after all the receiving side may not want to deal with these
unsolicited pings forever. In that case do you know the right place to
revert this behavior (l2ping is useful for testing).
