Hi, experts,<br><br>I have a question about link level security as below:<br>When there are 2 Bluetooth keyboard both connected with the same 1 Laptop&#39;s Bluetooth controller, and enabled link layer data encryption function, both use the same PIN do the authentication, will the encryption key be the same for both links in data stream? If they are different, then, host controller&#39;s baseband need to maintain the 2 keys for the 2 links in the flying, right?
<br><br>Thanks very much for your answer! <br>
