From: "Min Jun,Xi" To: linux-bluetooth@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-bluetooth-owner@vger.kernel.org List-ID: Hi All, I have one question about the "access address" of the link layer connection for BT-LE. In the volume 6 ("Low energy controller") of the current Bluetooth Specification V4.0, it is said that "The Access Address is a property of the physical channel. The Access Address is present at the start of every transmitted packet.". Also, in the Link Layer data format, there's one field to contain "Access Address". I know all of them are in the controller, but can I get the access address in Linux kernel? In the kernel's source code, I can only see the interface to operate on HCI layer and the upper layers. Can I use the HCI interface to get the "Access Address" property for one established BT-LE connection? I don't know how to do that. Can you help me? Thank you! -- best regards, Xi Minjun
