Hi all I am putting a JSR82 implementation on an Android device that uses BlueZ, accessing BlueZ via the dbus api. JSR82 has an API where you can set service class bits for a particular service you have registered. So the JSR82 implementation needs to be able to set the class of device in some way. I would like to add a dbus method to do this, and I'd like to know the opinion of BlueZ developers on this: 1. Is this a reasonable thing to do and submit a patch for ? 2. What would be a good approach, out of the following (or any other possibility I have missed) ? 2a. Add a dbus method to set service class bits for a registered service. This would set a new field in sdp_record_t. The existing function update_adapter_svclass_list in sdpd-service.c would read this new field in every service record when determining the service class bits to set. The setting gets cleared automatically when the service is removed. This seems like the cleanest solution. 2b. Add a dbus method to set service class bits, or all device class bits, globally for the dbus connection. There would have to be a list of dbus connections, each storing the connection's requested class. manager_update_svc would scan that list. The setting gets cleared automatically when the dbus connection is lost. 2c. Add a dbus method to set service class bits, or all device class bits, globally. This can just call the BlueZ internal method directly. The problems with this are (i) it doesn't work if multiple apps are trying to use it; (ii) the setting gets lost next time a service gets registered or removed, so the app needs to be aware of this and reapply its setting, and (iii) the setting remains if the app exits or crashes without removing it. I note that Bluecove-on-BlueZ does not implement this, therefore it fails the same conformance test that I am looking at.
