CONFIG_BT_BUF_CMD_TX_SIZE
¶
Maximum support HCI Command buffer length
Type: int
Help¶
Maximum data size for each HCI Command buffer. This value does not
include the HCI Command header.
This value is used by both the Host and the Controller for buffer
sizes that include HCI commands. It should be set according to the
expected HCI commands that can be sent from the configuration.
If the subset of possible HCI commands is unknown, this should be set
to the maximum of 255.
Defaults¶
255 if
BT_EXT_ADV
||BT_BREDR
65
