Dear community,
I am attempting to create a service that extends the functionality of
Bluez Pairing. I want to rewrite some of the functionality for
different paring methods (capabilities).
I read [this blog which uses Qt][1] to generate the code to create the
base code for the agent.
I used `gdbus-codegen` to generate the C code (like this[2]), using
the XML given in the blog in [1].
Then, in my main function, I acquired a SYSTEM BUS name and exported
all objects, including an object manager. My setup now looks like
this:[3]
Finally, I created a `callback` function based on the GDBUS signal
based on `handle-request-confirmation` which looks like this:
g_signal_connect(agent, "handle-request-confirmation",
G_CALLBACK (on_request_confirmation), NULL);
> The above code is in main()
int on_request_confirmation(CustomOrgBluezAgent1 *agent,
GDBusMethodInvocation *invocation, gchar* path,
guint32 passkey, gpointer userdata) {
g_print("Hello WORLD!");
set_trusted(path);
return TRUE;
}
> This is the actual callback function
My problem is that I am not able to have my Agent1 interface register
as a default agent. I tried invoking the `AgentManager1` in
`org.bluez` with `RegisterAgent` and `RequestDefaultAgent`, but it
doesn't seem to use the newly created service and I assume it uses a
separate one within the `org.bluez` service.
I have a couple of questions:
- Is this the proper way to implement a custom Agent1?
- How do I make it the default agent?
- How can I check what Agent is currently the default? It doesn't
appear anywhere in `d-feet` (the GUI d-bus explorer). I noticed the
agent implemented in Ubuntu though obex, but this is in Session (when
the bluetooth settings app is opened, the service appears in the
Session Bus):[4]
