For that purpose I've created .service file like this [ D - Bus Service ] Name = com . mycompany . servicename Exec = /home/ myuser / Workspace / service - start User = myuser Here I just changed the actual name of service and executable but this is not the point. I've double checked real names - it matches exactly. I've placed this file under name com.mycompany.servicename.service to /usr/share/dbus-1/services folder (I am

I'm trying to learn how to use D-Bus with C bindings. I've never used D-Bus before. I'm following this tutorial , which I assume is the official one (Freedesktop.org). I've read it until this paragraph that gives a first sample program , but unfortunately I don't see any indication on this page about how to compile it or which libraries to include.

I tried to add #include <dbus/dbus.h> at the beginning of the source file, and to compile with $ gcc -ldbus-1 -I/usr/include/dbus-1.0/ -I/usr/lib/i386

This is from the dbus-send man page : "...D-Bus supports more types

I'm written/registered an agent that sets it's mode to DisplayOnly; I expected that when a device connects the "RequestPasskey" callback would be called and that my agent would then be able to generate and return a new passcode, and that the remote end would be required to

With the last release of BlueZ (5.30) the highlight was the completion of the GATT D-Bus apis. My goal is to programmatically (in C), as a BLE client: scan for ble devices (which I can do with the hci layer) Connect to an advertising BLE device Get the UUIDs Execute Read and Write to handles The BlueZ community is strongly suggesting to use the GATT-Dbus api to accomplish this. After multiple searches and head scratching I was not successful to find a proper way or example that would perform this through GATT-DBUs api. It seems more complicate than just use directly the GATT layer.
