That one's clear enough from the earlier log snippet and source: Aug 29 00:54:47 RhoPC bluetoothd[4046739]: src/profile.c:ext_connect() Headset Voice gateway connected to FC:58:FA:7F:E5:18 Aug 29 00:54:47 RhoPC bluetoothd[4046739]: src/service.c:change_state() 0x562f6441d710: device FC:58:FA:7F:E5:18 profile Headset Voice gateway state changed: disconnected -> connecting (0) Aug 29 00:54:47 RhoPC bluetoothd[4046739]: src/service.c:change_state() 0x562f6441d710: device FC:58:FA:7F:E5:18 profile Headset Voice gateway state changed: connecting -> connected (0)
This ext_connect() seems to be called whenever a profile connection is completed, whether successfully or not, whether locally or remotely initiated. Above, we see the state changes it orchestrated -- it first transitions the HFP "service" to CONNECTING and then to CONNECTED pretty quickly: if (conn->service && service_set_connecting(conn->service) < 0) goto drop; ... if (conn->service) btd_service_connecting_complete(conn->service, err ? -err->code : -EIO); Each of these state changes gets propagated to a bunch of listeners -- one of which is policy.c. ========================= I think that first transition (to CONNECTING) should not have happened, because it takes away the ability of any listeners to judge whether a connection was locally or remotely initiated, and act accordingly. The HFP service should've simply gone from DISCONNECTED to CONNECTED -- that first IF block should be removed entirely. ========================= If a connection were indeed locally initiated, the service's state would've been set to CONNECTING way back, by btd_service_connect() probably since it looks to be the one that kicks off the connection. ext_connect() only has enough info to make that final jump to CONNECTED. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1941977 Title: PC streams music over low-quality HFP/SCO connection, instead of A2DP/AVDTP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1941977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
