Warning: setting this to 0 means that the application must ensure that queued TX buffers never need to be fragmented, i.e. that the controller's buffer size is large enough. If this is not ensured, and there are no dedicated fragment buffers, a deadlock may occur. In most cases the default value of 2 is a safe bet. config BT_L2CAP_TX_MTU int "Maximum supported L2CAP MTU for L2CAP TX buffers" default 672 if BT_BREDR default 65 if BT_SMP default 23 range 65 2000 if BT_SMP range 23 2000 help Maximum L2CAP MTU for L2CAP TX buffers. config BT_L2CAP_DYNAMIC_CHANNEL bool "L2CAP Dynamic Channel support" depends on BT_SMP help This option enables support for LE Connection oriented Channels, allowing the creation of dynamic L2CAP Channels. config BT_L2CAP_ECRED bool "L2CAP Enhanced Credit Based Flow Control support" depends on BT_L2CAP_DYNAMIC_CHANNEL help This option enables support for LE Connection oriented Channels with Enhanced Credit Based Flow Control support on dynamic L2CAP Channels. config BT_DEBUG_L2CAP bool "Bluetooth L2CAP debug" depends on BT_DEBUG help This option enables debug support for the Bluetooth L2ACP layer. endmenu
