* [PATCH BlueZ 0/2] AVRCP: Add support for Vol Up/Down operations on TG @ 2013-01-22 18:18 João Paulo Rechi Vita 2013-01-22 18:18 ` [PATCH BlueZ 1/2] avctp: Create ignore quirk João Paulo Rechi Vita 2013-01-22 18:18 ` [PATCH BlueZ 2/2] avctp: Receive and silent ignore Vol Up/Down operations João Paulo Rechi Vita 0 siblings, 2 replies; 7+ messages in thread From: João Paulo Rechi Vita @ 2013-01-22 18:18 UTC (permalink / raw) To: linux-bluetooth; +Cc: luiz.dentz, João Paulo Rechi Vita This series creates a new quirk called QUIRK_IGNORE to be able to accept and ignore certain keys. Then it uses this infrastructure to accept and ignore Volume Up/Down operations, instead of replying with "Not Implemented". Suport for Volume Up/Down is mandatory on TG side if we claim to support Category 2 (Monitor / Amplifier). It's also tested by PTS on test TC_TG_PTT_BV_02_I.

Motivation 16: Sending an AVRCP volume command to the MP may cause the MP to send again an AVRCP volume command to the RD device which could lead to an endless loop of AVRCP volume commands. Recommendation 17: If a device receives an AVRCP volume command, it shall not send back an AVRCP volume command. Motivation 17: This will also ensure that endless loop does not happen with existing devices which do not comply with the recommendation." So there is nothing against the RD accepting the Volume Up/Down it should just no send it back. -- Luiz Augusto von Dentz ^ permalink raw reply [flat|nested] 7+ messages in thread
