CONFIG_BT_BUF_ACL_TX_COUNT

Number of outgoing ACL data buffers

Type: int

Help

Number of outgoing ACL data buffers sent from the Host to the
Controller. This determines the maximum amount of data packets the
Host can have queued in the Controller before waiting for the
to notify the Host that more packets can be queued with the Number of
Completed Packets event.
The buffers are shared between all of the connections and the Host
determines how to divide the buffers between the connections.
The Controller will return this value in the HCI LE Read Buffer Size
command response.
