The current code didn't make use of information requests and so didn't receive information responses, too. I'd like to change that as it is recommended by the specfication to first interact with the remote peer by using information requests after a successful connection. I would like to ask the remote peer if it supports extended features, namely especially flow control, before I start request this technique. So far so good. So I send an information request via the l2cap_build_info_req() in the function l2cap_connect_rsp() whenever the connection response signals success. This works as expected and my Siemens S75 mobile phone responds with an information response immediately. Guess what, it send as a result the bytes =BB07 00 00 00=AB which indicates full extended features support. Wow. Now I'd like store this information in the corresponding socket so that I can continue the whole process with a configuration request. I would like to call l2cap_build_conf_req() within l2cap_information_rsp() like this: /* build configuration request */ l2cap_pi(sk)->conf_state |=3D L2CAP_CONF_REQ_SENT; l2cap_send_cmd(conn, l2cap_get_ident(conn), L2CAP_CONF_REQ, l2cap_build_conf_req(sk, req), req); But here is the problem located. From within an information response, I cannot reliably find the corresponding socket. All information pieces I get are the connection, the command header and the data. So there is no source or destination ID and the only function I could find which may return the socket for a connection is l2cap_get_chan_by_ident() like this: if (!(sk =3D l2cap_get_chan_by_ident(&conn->chan_list, cmd->ident))) { printk("---> no socket!\n"); return 0; } Unfortunately cmd->ident and the conn ident are not equal and so the socket cannot be found ... I have no clue what is wrong or what else I should do to get the socket from an incoming information_rsp() Martin ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
