CONFIG_BT_BUF_EVT_DISCARDABLE_SIZE

Maximum supported discardable HCI Event buffer length

Type: int

Help

Maximum support discardable HCI event size of buffers in the separate
discardable event buffer pool. This value does not include the
HCI Event header.
The minimum size is set based on the Advertising Report. Setting
the buffer size different than BT_BUF_EVT_RX_SIZE can save memory.
