As I suspected, even though the Delete Stored Link Key command is
mandatory from Bluetooth version 1.1 onwards (this controller supports
2.0) this controller doesn't have it mentioned in its supported commands
response (counting from 0 it should be bit 7 of octet 6). Therefore, it
might be possible to just move sending of this problematic command to
after receiving the supported commands response and making it
conditional to having its respective bit set in the mask. I'll be
sending another patch proposal soon.
