Hi Marcel,

Thanks for your comments.
We are working to resolve them.

We already have HCI_UART_REGISTERED bit in "hu->flags". I think, we can use it to know if HCI is ready or not.
We will define two recv handlers. "->recv" and "->recv_for_prepare"

OR let us know if you want us to use single "->recv" and have code under "if (HCI_UART_REGISTERED)" and "else" in our handler.
