Currently it is mandatory whenever Bluetooth support (CONFIG_BLUETOOTH) is enabled. if BLUETOOTH_LE config BLUETOOTH_HCI_CMD_COUNT int "Number of HCI command buffers" default 2 range 2 64 help Number of buffers available for HCI commands. config BLUETOOTH_MAX_CMD_LEN int "Maximum supported HCI command length" default 64 range 64 255 help Maximum length of each HCI command. config BLUETOOTH_HCI_EVT_COUNT int "Number of HCI event buffers" default 8 if BLUETOOTH_CONN default 4 range 2 64 help Number of buffers available for HCI events. This number should ideally be at least as large as the available outgoing buffers to make sure we've got enough buffers to handle bursts of Number of Completed Packets HCI events. config BLUETOOTH_MAX_EVT_LEN int "Maximum supported HCI event length" default 68 range 68 255 help Maximum size of each HCI event buffer. E.g. one big event for LE is the Command Complete for Read Local Supported Commands. It is a 3 byte Command Complete header + 65 byte return parameters = 68 bytes in total. config BLUETOOTH_PERIPHERAL bool "Peripheral Role support" default n select BLUETOOTH_CONN help Select this for LE Peripheral role support. config BLUETOOTH_CENTRAL bool "Central Role support" default n select BLUETOOTH_CONN help Select this for LE Central role support. config BLUETOOTH_CONN bool default n if BLUETOOTH_CONN config BLUETOOTH_ACL_IN_COUNT int "Number of incoming ACL data buffers" default 5 range 2 64 help Number of buffers available for incoming ACL data. config BLUETOOTH_L2CAP_IN_MTU int "Maximum supported L2CAP MTU for incoming data" default 65 if BLUETOOTH_SMP default 23 if !BLUETOOTH_SMP range 65 1300 if BLUETOOTH_SMP range 23 1300 if !BLUETOOTH_SMP help Maximum size of each incoming L2CAP PDU. config BLUETOOTH_ATT_MTU int "Attribute Protocol (ATT) channel MTU" default 50 if BLUETOOTH_SMP # BLUETOOTH_L2CAP_IN_MTU is big enough # for two complete ACL packets default 23 range 23 BLUETOOTH_L2CAP_IN_MTU help The MTU for the ATT channel. The minimum and default is 23, whereas the maximum is limited by CONFIG_BLUETOOTH_L2CAP_IN_MTU. config BLUETOOTH_SMP bool "Security Manager Protocol support" default n help This option enables support for the Security Manager Protocol (SMP), making it possible to pair devices over LE. if BLUETOOTH_SMP config BLUETOOTH_SIGNING bool "Data signing support" default n help This option enables data signing which is used for transferring authenticated data in an unencrypted connection. config BLUETOOTH_SMP_SC_ONLY bool "Secure Connections Only Mode" default n help This option enables support for Secure Connection Only Mode. In this mode device shall only use Security Mode 1 Level 4 with exception for services that only require Security Mode 1 Level 1 (no security). Security Mode 1 Level 4 stands for authenticated LE Secure Connections pairing with encryption. Enabling this option disables legacy pairing. endif # BLUETOOTH_SMP config BLUETOOTH_L2CAP_DYNAMIC_CHANNEL bool "L2CAP Dynamic Channel support" default n help This option enables support for LE Connection oriented Channels, allowing the creation of dynamic L2CAP Channels. config BLUETOOTH_GATT_DYNAMIC_DB bool "GATT dynamic database support" default n help This option enables GATT services to be added dynamically to database. config BLUETOOTH_GATT_CLIENT bool "GATT client support" default n help This option enables support for the GATT Client role. config BLUETOOTH_MAX_CONN int "Maximum number of simultaneous connections" default 1 range 1 16 help Maximum number of simultaneous Bluetooth connections supported. The minimum (and default) number is 1. config BLUETOOTH_MAX_PAIRED int "Maximum number of paired devices" default 1 range 1 32 help Maximum number of paired Bluetooth devices.
