Already spent a lot of time on this issue and it is really tricky.
Please give me some hint...
I have a remote control and need to find related services after boot in
order to set notifying on some characteristics. At this stage the remote
control is not connected and cannot be connected. This is not working
because after boot the services are not available via d-bus (empty).
Only if I then press a button, the services are cached and I can catch
this event and set notifying on the characteristics. However, this is
too late and I miss some buttons pressed.
When I connect the remote and then later (even far later) and even if
the remote is unpowered (no batteries) it is not a problem to find the
cached services (without service resolving) and then I am able to set
notifying on those characteristics.
Why does my BlueZ not cache the services of a paired and trusted device
over a reboot?
Thanks,
Martin
