RE: RE: Rfcomm qualification

Marcel, Have you two worked out a solution for this one (see message below)? Should I use the last patch you sent to test? -Daryl. > -----Original Message----- > From: Marcel Holtmann [mailto:marcel@xxxxxxxxxxxxxxxxxxxx] > Sent: August 5, 2003 3:04 PM > To: Max Krasnyansky > Cc: Daryl Van Vorst; BlueZ Mailing List > Subject: Re: [Bluez-devel] RE: Rfcomm qualification > > > Hi Max, > > > >The attached patch sets the default values for session and dlc > > >credits to zero and put in RFCOMM_MAX_CREDITS only if we > receive a PN > > >with 1.1 flow control. > > > > > >What do you think? > > > > I don't like this: > > > > @@ -746,7 +746,7 @@ > > pn->ack_timer = 0; > > pn->max_retrans = 0; > > > > - if (d->credits) { > > + if (cr || d->credits) { > > > > > > This basically means that we'll always request CFC even if > the other > > side explicitly told us that they don't support it.

RE: RE: Rfcomm qualification

Hi Daryl, > Have you two worked out a solution for this one (see message below)? I am working on another way to solve this problem. The patch in 2.4.18-mh8 should work, but it is not the best solution. > Should I use the last patch you sent to test? Give it a try, because it should pass the test.

l2cap connection over an already established ACL link

Hi all, I'm studing Bluez in pan configuration. I would like to know if bluez allows to setup a connection (by socket "connect" function i.e. the L2CAP_sock_connect function) in PAND on an ACL link that I have already established manually by HCI functions. I looked in the BLUEZ code and I can't get if the L2CAP_sock_connect ignores hci_create_connection function when the ACL link is already established. Thanks Ilario ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
