[PATCH BlueZ 2/2] btdev: Set Local RPA when own_addr_type is 0x03

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This enables the emulator to properly emulate the generation of a Local
RPA so it always set the random_addr when Create Connection sets 0x03 as
own_addr_type 0x03:
