Luiz pointed out that an explicit suspend API in Bluez may take advantage of OBEX enhancements and thus help avoid timeouts in peers when not telling them that we suspend. The exact API still needs to be determined. Either way, a new PIM Manager API is needed for suspend/resume. See the proposal for SuspendSync()/ResumeSync()/"status = suspended" in bug #70950 comment #1. Is that okay?
