This can be used to interface to a BLE controller via HCI protocol (either to a local BLE link-layer or to an external device over HCI UART). if WIRELESS_BLUETOOTH_HOST endif # WIRELESS_BLUETOOTH_HOST 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. The minimum (and default) number is 1. config BLUETOOTH_MAXSCANDATA int "Max scan data size" default 64 range 1 255 ---help--- Scan results will be buffered in memory until the user requests the scan results. This parameter specifies the maximum size of the advertiser data that accompanies the scan result. This contributes to a static memory allocation that will be greater than CONFIG_BLUETOOTH_MAXSCANDATA * CONFIG_BLUETOOTH_MAXSCANRESULT config BLUETOOTH_MAXSCANRESULT int "Max scan results" default 8 range 1 255 ---help--- Scan results will be buffered in memory until the user requests the scan results. This parameter specifies the maximum number of results that can be buffered before scan results are lost. This contributes to a static memory allocation that will be greater than CONFIG_BLUETOOTH_MAXSCANDATA * CONFIG_BLUETOOTH_MAXSCANRESULT config BLUETOOTH_MAXDISCOVER int "Max GATT discovery results" default 8 range 1 255 ---help--- GATT discovery results will be buffered in memory until the user requests the results. This parameter specifies the maximum results that can be buffered before discovery results are lost. config BLUETOOTH_BUFFER_PREALLOC int "Number of pre-allocated buffer structures" default 20 ---help--- This specifies the total number of preallocated buffer structures. This is for performance optimization. If additional buffer structures are needed, they will be allocated dynamically at some loss of performance. config BLUETOOTH_BUFFER_IRQRESERVE int "Reserved pre-allocated primitive structures" default 0 ---help--- If buffer structures can be allocated from interrupt handlers, then this specifies the number of pre-allocated structures that are reserved for for use only by interrupt handlers. This may be set zero to reserve no buffers for interrupt handlers. In that case, the allocation will fail if tasking logic has allocated them all. Interrupt logic will first attempt to allocate from the general, pre-allocated buffer pool that will contain up to (size CONFIG_BLUETOOTH_BUFFER_PREALLOC - BLUETOOTH_BUFFER_IRQRESERVE) entries. If that fails, then it will try to take a buffer from the reserve (size CONFIG_BLUETOOTH_BUFFER_IRQRESERVE). Non-interrupt logic will also first attempt to allocate from the general, pre-allocated buffer pool. If that fails, it will dynamically allocate the buffer with an additional cost in performance. NOTE: The Bluetooth stack never allocates buffers from the interrupt level. This setting only needs to be non-zero if your low-level Bluetooth driver needs to do such allocations. menu "Kernel Thread Configuration" config BLUETOOTH_TXCMD_STACKSIZE int "Tx command thread stack size" default DEFAULT_TASK_STACKSIZE config BLUETOOTH_TXCMD_PRIORITY int "Tx command thread priority" default 100 range 1 255 config BLUETOOTH_TXCMD_NMSGS int "Tx command thread mqueue size" default 16 config BLUETOOTH_TXCONN_STACKSIZE int "Tx connection thread stack size" default DEFAULT_TASK_STACKSIZE config BLUETOOTH_TXCONN_PRIORITY int "Tx connection thread priority" default 100 range 1 255 config BLUETOOTH_TXCONN_NMSGS int "Tx connection thread mqueue size" default 16 endmenu # Kernel Thread Configuration config BLUETOOTH_SMP_SELFTEST bool "Bluetooth SMP self tests executed on init" default n ---help--- This option enables SMP self-tests executed on startup to verify security and crypto functions. endif # WIRELESS_BLUETOOTH
