CONFIG_BT_DISCARDABLE_BUF_COUNT¶
Number of discardable event buffers
Type: int
Help¶
Number of buffers in a separate buffer pool for events which the HCI driver considers discardable. Examples of such events could be e.g. Advertising Reports. The benefit of having such a pool means that the if there is a heavy inflow of such events it will not cause the allocation for other critical events to block and may even eliminate deadlocks in some cases.
