その対策でBluetooth関係の設定ファイルを眺めてみた。
-DesireHD CyanogenMod6,7(/system/etc/bluetooth)
+Xperia x10 mini 2.1(/system/etc/bluez)
audio.conf
-# Do not require master role for incoming connections -Master=false +# Switch to master role for incoming connections (defaults to true) +#Master=truemain.conf
-DiscoverSchedulerInterval = 0 +DiscoverSchedulerInterval = 20 -# The link policy for connections. By default it's set to 15(0x000f) which is -# a bitwise OR of role switch(0x0001), hold mode(0x0002), sniff mode(0x0004) -# and park state(0x0008) are all enabled. However, some devices have -# connection stability issue or fail to setup SCO when the link is in park -# state, which requires park state bit cleared. -DefaultLinkPolicy = 7
現状、main.conf のみをDesireHD CyanogenMod7 に反映して、だいたい12時間くらい持つようになった。
main.conf
+DiscoverSchedulerInterval = 20
+DefaultLinkPolicy = 15
