I am so sorry, I reply to the incorrect thread in last mail. :-(
Hi, experts,
I have a question about link level security as below:
When there are 2 Bluetooth keyboard both connected with the same 1 Laptop'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's link manager need to maintain the 2 keys for the 2 links in the
flying, right?
Thanks very much for your answer!
