Hi Simon,
Thank you.
Yes, this issue is due to the main loop I used is:
while(dbus_connection_read_write_dispatch(bus, -1));
After replace it with the glib main loop, or implement a main loop with poll, the reply could be sent asynchronously well. By the way bluez uses glib main loop, so it is fine.
Thanks all of you to help me fix it!
Best regards
Fei Zheng

I suspect it's because BlueZ has an ordinary epoll/poll/select-based
main loop rather than using POSIX signals for this. If you have a
problem to solve, POSIX signals (as in signal()/sigaction()) are
usually the wrong solution.
POSIX signal handlers interrupt whatever else is going on (e.g.
libdbus blocking in read_write_dispatch, with a lock held) and run
code - it's almost as though you had two threads. That's a very
precarious state to run it - even malloc() is quite likely to crash!
That's why it isn't safe to call library functions, and that's
probably also why your code is deadlocking.
More or less the only safe thing to do in a POSIX signal handler is to
call simple syscalls like write() or close() (the well-known "pipe to
self" trick), to which you respond in the main loop.

That isn't true. Using D-Bus asynchronously is correct, and indeed,
recommended - but you have to do your asynchronous operations in a
supported way (e.g. with a main loop, or using GLib's GDBus and its
worker thread[1]), not via POSIX signals.

Confusingly, BlueZ has its own wrapper around libdbus, which uses the
namespace "GDBus*", "G_DBUS_*", "g_dbus_*", but is not the same thing
as GDBus, an object-oriented reimplementation of D-Bus found in GLib.
GLib's GDBus is what I recommend using.
Regards,
S
[1] Internally, GLib's GDBus uses a main loop in a worker thread, which
is OK because, unlike libdbus, it has a well-defined threading
model. libdbus wasn't thread-safe until recently, and perhaps still
isn't.

Hi Simon,
Thank you for your response.
Glib and Qt are licensed under GPL, if I use them, the code should be open, right? That is why I choose the low-level API.
In my test code the posix signal handler is used to send the reply asynchronously, it also could be replaced by a posix thread etc. As Chengwei said, the reply in dbus cannot be sent asynchronously, then I try to block in the message handler and send it synchronously. Thank you.

Both are available under LGPL, so you need not opensource your code. This
applies to dynamic linking only though.

GLib and Qt are both licensed under the Lesser GPL, a weaker copyleft
license than the GPL, which means they can be used in proprietary software.

D-Bus is designed to be used asynchronously from a main loop (event
loop, etc.) - see <https://en.wikipedia.org/wiki/Event_loop> and
specifically the "File interface" section. I recommend this approach.
In my experience, using threads to emulate asynchronous I/O only works
if you are very, very careful, and if not, you just get:
"You had a problem and you solved it with threads. Now you have two
problems, in parallel, and they interfere with each other."
Worse, using POSIX signals to emulate asynchronous I/O tends to result in:
"You had a problem and you solved it with POSIX signals. Now you still
have a problem, but it can be interrupted at any time by another problem."

Yes. But I still confused by it. Bluez use gdbus, and gdbus is also implemented by the dbus low api. I have checked the gdbus code with bluez, but it seems same with the way I used.
In object.c line 519, object_path_ref() calls dbus_connection_register_object_path() to register generic_table to handle the message. In object.c line 454, generic_message() is the message handler, and in this function process_message() is called to process the message, in line 232, when the method handler function is marked asynchronously, and the rely is null, DBUS_HANDLER_RESULT_HANDLED is returned directly instead of sending reply to client. >From the code it seems using the way glib works is same with the test code I attached. Thanks.

As you know, asynchronous is invalid. There are general two ways to
work around.
1. make it synchronous, then the server will block and then send back
reply, this may cause a timeout error if the data isn't ready in time.
2. broadcast a signal if the data is ready and the client then send
request to server.

The magic is GDBus, see below.
static GDBusMethodTable adapter_methods[] = {
{ "GetProperties", "", "a{sv}",get_properties },
{ "SetProperty", "sv", "", set_property,
G_DBUS_METHOD_FLAG_ASYNC},

So as Simon already suggested, maybe GDBus is your choice.
