CONFIG_BT_RX_STACK_SIZE

Size of the receiving thread stack

Type: int

Help

Size of the receiving thread stack. This is the context from which all event callbacks to the application occur. The default value is sufficient for basic operation, but if the application needs to do advanced things in its callbacks that require extra stack space, this value can be increased to accommodate for that.

Direct dependencies

(BT_HCI_HOST || BT_RECV_IS_RX_THREAD) && BT_HCI && BT

(Includes any dependencies from ifs and menus.)

Defaults

• 512 if BT_HCI_RAW

• 2048 if BT_MESH

• 2200 if BT_SETTINGS

• 1024
