CONFIG_BT_CTLR_LLCP_PER_CONN_TX_CTRL_BUF_NUM

Number of tx control buffers to be reserved per connection

Type: int

Help

Set the number control buffers that is to be pre allocated per connection
This defines the minimum number of buffers available for any connection
Setting this to non zero will ensure a connection will always have access
to buffer(s) for control procedure TX

Direct dependencies

!BT_LL_SW_LLCP_LEGACY && BT_CONN && BT_LL_SW_SPLIT && BT_CTLR && BT_HCI && BT

(Includes any dependencies from ifs and menus.)
