CONFIG_BT_BUF_ACL_RX_COUNT

Number of incoming ACL data buffers

Type: int

Help

Number or incoming ACL data buffers sent from the Controller to the
Host.
In a combined Host and Controller build the buffers are shared and
therefore Controller to Host flow control is not needed.
In a Host only build with Controller to Host flow control enabled
the Host will inform the Controller about the maximum number of
buffers by setting this value in the Host Buffer Size command.
When Controller to Host flow control is not enabled the Controller
can assume that the Host has infinite amount of buffers.
