Re: l2ping only works for 10 seconds with 2.6.27

Hi Nick,

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?

it is not fully intentional, but it result due the fact on how we had to implement the Simple Pairing support. Problem here is that l2ping can not create a remote reference count of the connection. So BlueZ will clean up the ACL link. And we do have to do that since otherwise we waste power with an unused link.

So if you do l2test -P 1 -n <bdaddr> first and then l2ping you will see that the ACL link stays up since the l2test hold a remote reference count.

Regards

Marcel
