Hi all,
We are developing an implementation of HDP and MCAP for bluez. We are triying
to perform many connections between two devices but when we make the second
connection it is not created correctly.
We are using a defer connection (we passed a confirm callback to the
bt_io_listen function) and we think that we are missing something but we
can't find what. If we used the connection callback (not defer) all the
connections are done successfully.
We are listening with the following code:
static void confirm_cb(GIOChannel *chan, gpointer user_data)
{
...
node->chan = g_io_channel_ref(chan);
...
/* All is ok */
return;
drop:
/* Connection refused */
g_io_channel_shutdown(chan, TRUE, NULL);
}
....
chan = bt_io_listen(BT_IO_L2CAP, NULL, confirm_cb, NULL,
NULL, &gerr,
BT_IO_OPT_SOURCE_BDADDR, &src,
BT_IO_OPT_PSM, 0x1001,
BT_IO_OPT_SEC_LEVEL, BT_IO_SEC_MEDIUM,
BT_IO_OPT_INVALID);
...
Any ideas?
Regards and thank.
Jose.

You're rigth, we forgot the bt_io_accept call.

Im not really sure what is the problem but maybe it is the missing
bt_io_accept, but of course it can be that you just hide it in those

The listen part at least seems ok.
