CONFIG_BT_CTLR_DF_MAX_ANT_SW_PATTERN_LEN

Maximum length of antenna switch pattern

Type: int

Help

Defines maximum length of antenna switch pattern that controller
is able to store. For nRF5x-based controllers, the hardware imposes
the value is within range 3 to 40, where last value is maximum.
For general use cases Bluetooth Core 5.1 spec. required the value
to be within range 2 up to 75.
