* [bluez PATCH v2] avrcp: include all player settings in notif event @ 2020-07-08 4:19 Howard Chung 2020-08-04 8:26 ` Archie Pusaka 0 siblings, 1 reply; 7+ messages in thread From: Howard Chung @ 2020-07-08 4:19 UTC (permalink / raw) To: linux-bluetooth; +Cc: luiz.dentz, Howard Chung, Archie Pusaka According to AVRCP 1.6.2 spec section 6.7.2 table 6.39, all player application settings should be returned to the CT and let CT to determine which settings have changed. Currently bluez only returns the changed attribute instead. This patch also addresses a potential issue on which the number of application settings mismatches with the actual number returned.
