Once the API is upstream, you will be able to register your own services using D-Bus. There will be example C code demonstrating the API, and documentation in doc/gatt-api.txt. > - My version of bluez is4.98-2ubuntu7 .

Unfortunately, you will need to use a more recent BlueZ in order to use the future API. You can build your own D-Bus library and BlueZ from sources (make sure to install in a separate place , e.g. /opt/bluez, instead of overwriting any files in /usr). Current status of the upstreaming process: - The internal C API for GATT service registration, as well as the attribute database format, was rewritten. Therefore we need to migrate existing internal profiles to this new API. - We sent patches for GATT Service and Characteristic registration. These initial patches do not export the services over the LE channel yet (they are only available using a local UNIX socket). This intermediary step is necessary in order to not break current supported profiles. - We will be able to export the services on the LE and BR/EDR channels once the internal profiles are migrated to the new C API. I'm currently working on this step. Summary: the latest BlueZ does not support external GATT services yet, but we hope to have basic support upstream (with an experimental API) very soon.
