If the path is the endpoint path instead, clear all streams associated with the endpoint. Commit: 1a2bba8fd9ba5b4eb04429f3ff0f27eef6bcdd02 https://github.com/bluez/bluez/commit/1a2bba8fd9ba5b4eb04429f3ff0f27eef6bcdd02 Author: Pauli Virtanen <pav@xxxxxx> Date: 2025-05-04 (Sun, 04 May 2025) Changed paths: M doc/org.bluez.MediaEndpoint.rst Log Message: ----------- org.bluez.MediaEndpoint: add client role Reconfigure Add a simple way for the sound server to reconfigure a BAP unicast endpoint, by calling org.bluez.MediaEndpoint.Reconfigure(). This shall destroy all streams of the endpoint, and restart the SelectProperties() configuration flow from the beginning. Since it may be necessary to reconfigure multiple endpoints at once to correctly make bidirectional CIS, add Defer argument to just mark eps for configuration. In future, org.bluez.MediaEndpoint.SetConfiguration() could be changed to handle unicast in the same way as broadcast: only create streams. This allows sound server to have full control over stream configuration itself, and not rely on bt_bap_select().

False for AC6(i) and other multi-stream configs. * No way for ASE in Config state be configured with different codec. * Assuming ASE enters idle state at end of stream life cycle. False for some devices like Sony headsets, which always cache codec config so RELEASING -> CONFIG always, never RELEASING -> IDLE, so ASE never go IDLE again. * Assuming Unicast Client upper layer always creates streams for all non-idle ASEs. False, as when switching between duplex & sink-only modes, only some streams shall be used regardless of whether Server is caching config or not. In practice, these currently prevent reconfiguring ASEs on devices which cache codec config, and multi-stream configs work only accidentally (and fail if server does Config codec itself, like some devices do). Minimally fixed design for Unicast Client streams: Streams correspond 1-to-1 to ASEs in non-IDLE state. Track explicitly which streams upper level is using: - bt_bap_stream_new() always makes new stream with client_active=true - bt_bap_stream_discard() releases stream and marks client_active=false Streams (ASEs) with no active client may be reused when upper level asks for a new stream. Streams with no active client may have their lpac changed. The need_reconfig state is a bit ugly, but not really avoidable. Streams with no active client shall be ignored when constructing bidirectional CIS pairs. Streams shall clear transport and detach io on RELEASING. (cf BAP v1.0.2 §5.6.6). Also unlink them since QoS is gone at that point. Streams shall have transport only for >= QOS state. (Server streams work differently, which makes sense since upper level cannot acquire them before they are pending.)

If the ASE was in CONFIG state before reconfiguration, this gets done in wrong order. Track explicitly that bap_state() is done after bt_bap_stream_config(), before proceeding to QoS.

TODO: this is not fully right, also new stream QoS should be delayed if CIG is active, so that it doesn't get assigned into a new CIG which controllers may not support Compare: https://github.com/bluez/bluez/compare/0d49b7b52e33%5E...df2813147498 To unsubscribe from these emails, change your notification settings at https://github.com/bluez/bluez/settings/notifications
